RadeOn 8500, ARB vertex & fragment programs

[Rodéric]

Do anyone know if and when a driver set for the ATI RadeOn 8500 will include :
-ARB vertex program ?
-ARB fragment program ?


Cause I need them ^^
(don't want to support none ARB extensions, atm)

The ARB_fragment_program extension is based on the GL_ATI_fragment_shader extension, so your question is pretty much moot.
ATI set the standard for it(they are the only vendor with PS1.4 at the moment) and OpenGL simply adopted it with a few tweaks. Read the OpenGL meeting notes of last month to see what I'm talking about.

In other words:

ARB_fragment_program = GL_ATI_fragment_shader

As to GL_ARB_vertex_program, the extension is already included in the drivers, perhaps you need to do your homework before you ask questions next time.


Here, I had bookmarked the link of last month's meeting notes:

Have a nice time reading

Ahem, there's no connection between GL_ARB_fragment_program and GL_ATI_fragment_shader. The ARB_fragment_program is R9700 / NV30 style fragment shading, the ATI_fragment_shader is the old R8500 shader extension. (Which btw now has been "deprecated" and replaced by GL_ATI_text_fragment_shader to better fit the ARB_vertex_program framework)

ROTFL, it seems someone has to do his homeworks too.

hmrm...
That doesn't answer my questions, Humus (I believe) already told in another thread that the next ATI drivers will include ARB vertex program, but when, and what about ARB fragment program ?

I've an ATI RadeOn 8500 + Catalyst 2.3 drivers on Windows 2000, and neither extensions are returned by glGetString( GL_EXTENSIONS ).


And because someone's answer upset me, here's what I got :

Now if you see ARB_fragment_program or ARB_vertex_program, I must be blind

Ingenu, the latest unofficial beta 6193 support the GL_ARB_vertex_program for the 8500. The GL_ARB_fragment_program will never be supported on the 8500 as it simply doesn't have that kind of functionality. On the 8500 you will however get the GL_ATI_text_fragment_shader which works somewhat similar (uses a text parsing interface), but with the old GL_ATI_fragment_shader functionality. It's not supported yet however, and I have no idea how soon it'll be supported either.

Thank you Humus.
I'll download those unofficial drivers.
