2 Where is Vega Prime Installed

 
 

The Environment variable MPI_LOCATE_VEGA_PRIME should point to the root directory were Vega Prime has been installed

 

On Windows the default is normally

 C:\Program Files\MultiGen-Paradigm

 

On Linux the default is normally

  /usr/local/MultiGen-Paradigm

 

On Irix the default is normally

 /usr/local/MultiGen-Paradigm

 

Binary files such as ( .dll, .exe,  ) are installed to

$(MPI_LOCATE_VEGA_PRIME)\bin

 

Lib files such as ( .lib, .so, .a ) are installed to

 

$(MPI_LOCATE_VEGA_PRIME)\lib

 

Include files are installed to

$(MPI_LOCATE_VEGA_PRIME)\include

 

$(MPI_LOCATE_VEGA_PRIME)\include\VegaPrime

 

$(MPI_LOCATE_VEGA_PRIME)\include\vsg

 

Documents, User Guides, Help files etc are installed to

$(MPI_LOCATE_VEGA_PRIME)\docs\.....

 

Resources, models, textures, Samples, Example code files are installed to

$(MPI_LOCATE_VEGA_PRIME)\resources\.....

3 What Environment Variables does Vega Prime Use

Vega Prime uses the following environment variables


 

MPI_LOCATE_VEGA_PRIME  the root location of where Vega Prime has been installed

MPI_INSTALL_RESOURCE_DEFAULT the root location where Vega will look for the Resources directory

MPI_INSTALL_DEFAULT same as MPI_LOCATE_VEGA_PRIME but default for all MPI products, you should useMPI_LOCATE_VEGA_PRIME

4   Can I use Vega with Vega Prime on the Same Machine

 

Yes you can install and use Vega and Vega Prime on the same machine, these products are independent of each other

5   How do I port My Vega Code to Vega Primer

Unfortunately there is no easy answer on how to Port you Vega applications to Vega Prime  

Vega Prime in one sense is very similar to Vega and you will see very similar names and terminology

There is logical mappings of Vega types to Vega Prime Classes

vgWindow - vpWindow

vgChannel - vpChannel

vgObject - vpObject

etc.

But the main issue is the while Vega was written in C++ it only provided a C interface and Vega Prime is provided only with C++ interface and function call  are different, there are many more in Vega Prime and some mapping and naming conversion are different etc.

So many things you have written at the top level of Vega should port relatively straight forward to Vega Prime, as long as you look at the docs, headers and samples etc.

6 Are there any Tools to Help Port Vega to Vega Prime

Basically no there are no tools to help you port from Vega to Vega Prime.

While they both share many concepts and class names, the differences between Vega's C based API and Vega Prime's C++ interface are too great to be able to provide porting tools or scripts


The one tool that is provide is with the vpPathing Module and that has a command line tool to will read the old Vega Navigator and Path files and create simple Vega Prime equivalents

7   Can I use Visual Studio 7.x with Vega prime 1.XX

Overall the answer is no you cannot use Vega Prime 1.2x with MicroSofts Visual studio 7.1 or above. Vega Prime 1.xx was built with Visual Studio 6.0 and you STL PORT. This causes lots of problems when trying to compile with 7.1.

Having said no, some people have managed to compile and run Vega Prime 1.22 with Visual Studio 7.1,  so it may work it all depend on what bits and pieces of Vega Prime you using, if your using a lot of the STL interface as opposed to the older deprecated get methods it probably will not compile

8  What is Lynx Prime

LynX Prime is the graphical user interface for defining, editing, and previewing Vega Prime applications, LynX Prime builds on the functionality originally found in the original Vega Lynx

LynX Prime is XML based application providing an extensible point and click graphical user interface that increases productivity by enabling changes to changes to:

application functionality, visual channels, multi-CPU allocation, eye-points, observers, special effects, time of day, system configuration, models, databases, and more at the point of application deployment.

Access to 'Active Preview' also allows many settings to be modified, and previewed instantly, without re-starting of the application. LynX supports end-user reconfigurability of delivered systems for non-programmers.
 

9 What is an ACF File

LynX Prime is an editor for Application Configuration Files (ACF's) which use XML to store the configuration data.

An ACF contains all the information that a Vega Prime application needs at application initialisation time as well as information to be used during runtime.

A single Vega Prime executable is capable of producing a variety of simulations by interpreting different ACF's. As with any editor, you may create, view, modify, and save these files.

From LynX Prime you can launch an application that uses an ACF to preview the results before saving the configuration for later use.
 

10  Can I use my Vega ADF's in Vega Prime

Unfortunately the short answer is no you cannot use old Vega ADF files in Lynx Prime

The long answer is no you cannot use old Vega ADF files in Lynx Prime ;), there is simply just to much difference between Vega and Vega prime to make this possible.
 

11   Can I have Vega Prime 1.2x and Vega Prime 2.0 on the Same machine

Out the Box no you cannot have Vega Prime 1.2x and 2.x installed on the same machine, The Vega Prime install will not allow you to install if it detects a previous version installed.

You could probably have the 2 versions installed with a bit of work and messing around.

You would have to do something along the lines of:
 

• Copy the Vega 1.2x directories to new directory,
• Uninstall Vega Prime 1.2x
• Install Vega Prime 2.x

Then you will need to change the Environment variables to point to which version you are using
 

• MPI_LOCATE_VEGA_PRIME
• MPI_INSTALL_RESOURCE_DEFAULT

12 Does Vega Prime have Navigators and Paths        

As of Vega Prime 1.2 yes Vega Prime has a Pathing module, with the equivalent of Navigator and Paths etc.

The Navigator and Pathing has been completely re-designed and re-written and is extremely more functional and powerfully  and use a less resources than the old Vega pathing

The new vpPathing module is part of the base product and is fully coordinate system aware including round earth
 

13 Where is the path Tool in Vega prime 1.x

The Vega Prime Path tool was released with Vega Prime 1.21, it is currently only available on Windows version for Vega Prime 

The path tool like Pathing Module has been completely re-written and re- designed, the Path tool can be access from the Tools menu in Lynx Prime

Currently there is no path tool for Linux or Irix, so you have to create Navigator etc through code for those platforms
 

14 Where is the Object Editor

Unfortunately currently there is not Object Editor in Vega Prime 1.x or 2.x


If you need to change the properties of a 3d database then you will need to used a modeling package such as Creator or Geo Pro

Go Shout at MPI if you need a Object editor, if the get enough shouts they may consider an Object editor for Vega Prime at some point

15   What is MetaFlight

MetaFlight is a formal database description specification.  MetaFlight describes the structure, organization, file naming and coordinate systems of all the dataset's that comprise a single more complex database.

MetaFlight provides the bridge between database generation tools and runtime applications. MetaFlight simplifies data integration and optimizes real-time-paging efficiency by communicating the metadata that enables runtime applications to take advantage of the database structure. MetaFlight aims to provide:

 

• High-level description of visual databases
• Provides a concise and consistent publishing format
• Extends OpenFlight data-model to include higher-order objects
• "Database" objects identify version and ownership information
• "Dataset" objects partition database into thematic layers
• "GridStack" objects describe database tiles as a multi-layer system of grid cells
• "Filename Pattern" objects can describe dataset's containing thousands of files
• "Coverage" objects define geo-location of dataset's
• "Coordinate System" objects describe complete coordinate information about all files in a dataset
• XML-compliant

16 What applications Support MetaFlight

 

MultiGen Paradigms's Creator Terrain Studio (CTS) is the main producer of MetaFlight, along with several tools that support MetaFlight Directly

VegaPrime is the main consumer of MetaFlight files, along with Vega Prime Module LADBM ( Large Area Database Management)the

The Blueberry 3d Module for Vega Prime also supports MetaFlight.

17 Are there Any Other Products that Support MetaFlight

At the time of writing this FAQ only MPI products and Vega Prime Modules offer support for MetaFlight.

18   Does Vega Prime Support Shaders

Yes as of Vega Prime 1.2x Shaders have been directly supported by Vega Prime.

At present Vega Prime 1.2x and 2.0 on supports only Nvidia's CG shader language directly.

Support for GLSL shaders should be forth coming in a Minor release.

19  Where are the Shader Examples/Samples

Samples are typically installed to $(MPI_LOCATE_VEGA_PRIME)\resources\<Product Name>\...

In Vega Prime 1.2x the shader examples can be found in $(MPI_LOCATE_VEGA_PRIME)\resources\vsg

In Vega Prime 2.0 the samples are nolonger shipped with the product. MPI now only provides shader examples via their support department and you need to contact them directly
 

20 Where have the Samples gone in Vega Prime 2.0

You may have noticed that some of the samples there were provided with Vega Prime 1.2x distribution are not in the Vega Prime 2.0 distribution.

MPI have removed several examples programs from the Distribution and made them only available through the MPI support department. This means that you have to have a maintenance contract to get access to the samples. Plus you have to figure out if there is an example that may do what your asking.

The removal of samples from the distribution is a little disturbing especially when your paying several thousands of dollars for the product in the first place.

21   Do I Need a new License for Vega Prime 2.x

If you are upgrading from a previous version of Vega Prime then yes you will need a obtain a new license for Vega Prime 2.0 from MPI.

MPI has updated the license mechanism for Vega Prime to use the FLEXlmCRO license mechanism and thus your old 1.2 license will no work with the new license manager

22   Can I have Vega Prime 1.2x and 2.0 license Mangers Installed

Yes you can have both the Vega Prime 1.2x License manager installed and the new Vega Prime 2.0 manager. They are different programs and resources.

Note, you have to work a little to have Vega Prime 1.2x and Vega Prime 2.0 installed on the same machine, See FAQ 11

 

23  How do I get a New License for Vega Prime 2.0

You must contact MPI directly to obtain a license for Vega Prime. U can use the following procedure to request a permanent license from MPI:

• On Windows, choose Start >Programs > MultiGen-Paradigm > MPI License Tools > License Tool.
   
• In the Select Operation panel, select Get Host Information.
   
• Click Next to display the Get Host Information panel.  The panel will displays the Host ID information that is used for your license request.
   
• You can copy all of the Host ID information in this panel, or click Save As to save the information in a text file. Send this information in an email to

  MultiGen-Paradigm at: unlock@multigen-paradigm.com : with :
   

• The Host ID information
   
• The license type: node-locked or floating
   
• Your Customer ID number (found on your Vega Prime CD sleeve)

24 Must I have Admin Writes to install Vega Prime

To install Vega Prime you will need to have Administrator rights when installing Vega Prime. The License manager need to access resources that requires administrator rights.

Once Vega Prime has been installed you can develop and run with normal User rights.

Note to get the best performance you should run you application on Windows with Vega

25 Will my Vega Prime 1.2x Code work in Vega Prime 2.0

For the most part your Vega Prime 1.2x should compile OK with Vega Prime 2.0.

Make sure you follow the installation instructions and note that on windows you have to use Visual Studio 7.1 or later, you cannot use Visual studio 6.x with Vega Prime 2.0

See the MultiGen-Paradigm's FlightIG page as part of the Visual Simulation services
 

33 What are VSB files

 

VSB (Vega Scene-Graph Binary), is an optimized extensible format for loading data into the runtime. Basically vsb files contain a complete binary image of the graph from an arbitrary "root" node.

VSB files typically load 10x to 100x times faster than the native modeling formats such as .obj, .3ds, .flt etc..

VSB (like the Vega Scene Graph) can be easily extended to include derived nodes and structures, and provides the means for incorporating custom encryption schemes to protect intellectual property. VSB files can also be streamed via sockets (TCP or UDP), read in from memory or from disk.
 

34   How Can I Generate VSB Files

VSB files can be created in a variety of ways including: 
 

• Through the VSB Generation Utility to_vsb
• Using Creator Terrain Studio
• Through the API of the Vega Scene Graph

35  Can I use FST Files with Vega Prime

Uhmm well NO.

FST files are the native binary format of Vega and thus are not compatible with Vega Prime.

You will need to Generate equivalent binary format for Vega Prime, VSB files from your original source models

36   Can I use PFB file With Vega Prime

Nope, you cannot

PFB files are the native binary format of SGI's OpenGl Performer and thus are not compatible with Vega Prime.

You will need to Generate equivalent binary format for Vega Prime, VSB files from your original source models.

Another approach if you have the Performer Libraries available would be to write a loader, OSG uses this method to load PFB files.

37 Should I keep my original files after converting to "VSB"

Absolutely yes you MUST MUST MUST keep your original model sources files that you used to create your "VSB"  files with

Due to the binary nature of the "VSB", they  can easily be come none compatible with newer versions of Vega Prime and thus requiring for the "VSB" files to be re-generated

38 Are "VBS" files forwards compatible

 

Not really, the VSB files maybe compatiable among minor revisions of Vega Prime.

But due to the binary nature of the "VSB", they  can easily be come none compatible with newer versions of Vega Prime and thus requiring for the "VSB" files to be re-generated 

So keep your orignal source files safe.....

39   How do I use TO_VSB

to_vsb can be invoked as a commnad line tool or with a GUI. (For GUI instructions see the documentation with Vega Prime).
 

to_vsb [ <INPUT file or directory> [<OUTPUT file>]] | [-it] [-ct] [-cm] [-f] [-c] [-clp] [-cn] [-og] [-pq] [-p <SEARCH PATH>] [-o <OUTPUT FILE>] [-do <DEBUG OUTPUT FILE>] [-n <NOTIFY_LEVEL>] [-noconsole]

 

-it  : inline textures

 

-ct  : compress textures

 

-cm  : disable compatibility mode

 

-f  : disable perform flatten traversal

 

-c  : disable perform clean traversal

 

-clp  : disable combine light points

 

-cn  : disable compute normals

 

-og  : disable optimize geometry

 

-p  : use specified search path

 

-o  : generate specified output file

 

-do : use specified output file for debug output

 

-n  : use specified notification level, i.e. LEVEL_DEBUG

 

-noconsole   : suppress console debug output

 

40 What are DDS Textures

The Direct Draw Surface (DDS) format is an optimized, compressed format that contains the binary representation of an image, as it is used by the hardware.  

Any image format supported by Vega Prime can be converted to DDS as an interim step for increased performance.  

The graphics hard ware handles DDS textures directly, which mean no decompression is needed by the texture loader. This means that when using DDS  textures loading is faster,  throughput is increased, while on disk storage requirements are decreased,  more textures or higher quality texture can be used etc.

41   Should I use DDS Textures

Generally I would say yes you should use DDS textures if possible and you hardware supports the format.( Most cards today do 2004+)

By using DDS format textures you gain from faster loading and less memory consumption.

42  How do I Convert Texture to the DDS Format

Vega Prime provides a utility program to_dds to convert textures to the DDS format. The program can be invoked as a command line tool or with a GUI (For GUI instructions see the documentation with Vega Prime).

to_dds [<INPUT file or directory>] | [-m] [-a] [-i] [-o <OUTPUT FILE>] [-p <SEARCH PATH>] [-do <DEBUG OUTPUT FILE>] [-n <NOTIFY_LEVEL>]

-m  : generate and compress mipmaps

-a  : override RGBA as RGB (e.g. 5551 -> Compressed RGB)

-o  : generate specified output file

-p  : use specified search path

-do : use specified output file for debug output

-n  : use specified notification level, i.e. LEVEL_DEBUG

-i  : invert (flip) the image when saving it to disk

43  Why do my DDS Textures look Inverted

 

What you are seeing is not a bug but is correct for  DDS (Direct Draw Surface) textures and depends on how you generated them.

As DDS was designed by Microsoft and thus originally intended for Direct X, which has its origin in the upper left corner, while OpenGL  has its origin in the lower left corner.

Basically you need to tell your DDS generation tool to invert the image,many tools can do this some don't

You can use the Vega Prime utility program to_dds to do the inversion for you using the '-i' command line switch

44  Are the other DDS tools Available

 

There are many DDS utilities and tools available these days, a quick Google search should find you many of this quite quickly

Nvidia provide several DDS tools including source code( See their developer site)

Nvidia's DDS tools can be found here http://developer.nvidia.com/object/nv_texture_tools.html

45  Can I use MFC with Vega Prime:

 

Yes you can use MFC with Vega Prime.

A sample was shipped with Vega Prime 1.x in (MPI_LOCATE_VEGA_PRIME)\resources\samples\vegaprime\vp\vp_mfc

But in Vega Prime 2.0 the sample is no longer shipped with the products and you will have to contact MPI support and ask for the specific sample
 

46 Can I use QT with Vega Prime

Yes you can use QT with Vega Prime, unfortunately MPI does not ship a code sample that shows how to use QT GUI frame work.

I don't believe  MPI support currently that has a sample Vega Prime available, they may have a VSG based sample, again that used to ship with Vega Prime 1.x

47  Can I use Vega Primer In ActiveX Container

 

Yes, yep I did say YES.

Unlike old Vega Classic, Vega Prime can be used with-in a container such as an Active X control or .Net Form etc.

A little care is needed to ensure that Vega Prime is shutdown correctly.

Unfortunately no sample is shipped with Vega Prime. It is possible that MPI Support may have a sample, and they might not.
 

48  Is there a COM or .Net Interface for Vega Prime

No, Vega Prime does not have a COM or .NET interface, it would be Windows only.

Although there is no reason why you could not write you own wrappers for COM, .NET or other similar technology

49  Does Vega Prime have a TCL/TK Interface

Nope, unfortunately currenlty Vega Prime does not have a publically availble TCL/TK like Vega Classic had

50 Does Vega PrimeSupport Sound

As of the release of Vega Prime 2.0, Vega Prime now(finally) supports 3d spatial sound in the new vgAudio module.

Note unlike Vega Classic were MPI wrote all the Audio code, the vgAudio is basically a wrapper around the Open source project OpenAL
