jogl on Solaris Sparc XVR.2500

Hi,

some of the examples and the NASA World Wind application does not run on my Sun Ultra 45 with a XVR-2500.

Can someone test jogl or Nase World Wind on another Sparc Plattform?

Regards

NASA World Wind requires compressed texture (DXTn) support which I would bet is what isn’t working on the XVR-2500.

Unfortunately I don’t even have one of these in house (an XVR-600 is the best I have). The base functionality of JOGL should work, but you’re going to be limited by what the graphics hardware supports.

But the XVR-2500 supports compressed texture GL_ARB_texture_compression.

What compressed texture formats does it support? What’s the output of demos.printext.PrintExt from the jogl-demos workspace?

The output is :

Neither GL_EXT_texture_compression_s3tc nor GL_NV_texture_compression_vtc are supported which indicates to me (and the JOGL implementation) that DXTn texture compression isn’t supported. If you can show otherwise then we can figure out how to add a code path to JOGL’s TextureIO implementation to handle this.

Hm, then I think I know why Nasa World Wind does not show the globe.

The XVR-2500 is a Wildcat Realizm 500 and this card should support the S3tc compression.

I wrote an email to the solaris developers if it is possible to enable S3tc compression in the OpenGL API for Sparc.

Thanks for your help.
