[gl4java-usergroup] texture compression

[Alban C. <aco...@wa...>]

Has anyone sucessfully used ARB texture compression with gl4java ?

I'm running a geforce 2 MX and my board reports it is not available when
using gl4java, while Nvidia developer site has papers on implementing
ARB texture compression on geforces.

Calling GLContext.gljTestGLProc("GL_ARB_texture_compression", false)
returns always false.

Same for :

GL_COMPRESSED_RGB_ARB

GL_COMPRESSED_RGBA_ARB

GL_COMPRESSED_ALPHA_ARB

GL_COMPRESSED_LUMINANCE_ARB

GL_COMPRESSED _LUMINANCE_ALPHA

 

Anyone have an idea ?

Hi Kenneth,

Thanks for the tip. Unfortunately, it doesn't work ! :)

If I test for extension availability with glVertexArrayRangeNV, I get :
GLINFO: glVertexArrayRangeNV (1): loaded !

If I test for extension availability with CompressedTexImage2DARB, I get
:
GLINFO: CompressedTexImage2DARB (3): not implemented !

This page http://www.3dnature.com/glbench.html reports
ARB_texture_compression is available with any kind of Geforce 2 though.

Is there any possibility the extension could not have been mapped with
gl4java ?

Regards,

Alban
