I was trying out these 27.00 drivers that seem to have fallen off the back of one of Nvidia’s lorry’s. The rumours about new extensions are true… heres the ones that look new to me, from the extension string.
GL_NV_occlusion_query
GL_NV_vertex_array_range2
GL_NV_vertex_program1_1
Can’t wait for the new specs for these to be published…
Isn’t NV_vertex_array_range2 quite old?
I dont know… it’s not in my current spec…
perhaps I should get a new one…
I don’t think GL_NV_vertex_array_range2 is new, i’m already using it in my program, and i think you can find the specs in the opengl extension registry. If i remember well, it’s a little modification of the “normal” VAR extension which doesn’t cause an internal flush in some situations.
The GL_NV_occlusion_query sounds interesting. Is/will it be like the HP occlusion test ? I’ve always been willing to use it in my programs, but it’s only present on very few cards, limiting its interest.
Y.
HP occlusion test is listed also…

That new vertex program extenstion sounds pretty interesting to me. That and the GL_NV_occlusion_query extension sounds cool. Hmmm, i smell a geforce 4.

Nutty: maybe you’ll get even a bigger list by activating NV25Emulate??

I tried that but the new drivers don’t show anything new. Some time ago I saw NV_fragment_program in one of the drivers ( and NV_texture_shaders3 ), so I know what I’m looking forward to ( very soon I hope ).
Anyone(NVIDIA) knows if EXT_multi_draw_arrays works with VAR?
-Lev
I just looked through the nvoglnt.dll 27.10 and found NV_point_sprite and NV_texture_shader3 in addition to what Nutty listed, nothing with NV_fragment_… though

You can find NV_fragment_program in drivers 21.81, 21.85 and 21.88 ( possibly others ). Introducing NV_point_sprite seems a bit strange, I thought ATI was working on such an extension ( I hope they can agree on this one extension ).
hm yeah… nvidia and ati:
how about developing some extensions TOGETHER?! would be much more simple for everyone…
i dont think there can be much difference for ati pointsprites and nvidia pointsprites so why 2 exts?
hm fragment-program… sounds like real textureshaders for me (lookups not prebuild in hardware but simple after doing some userdefined program (like ps1.4 + )
if this is gf4 then i’ll go for one possibly (if its not too expensive…)
I remember NVIDIA talking about the occlusion query when the GF3 came. (they said you would be able to query whether a triangle you specify would be occluded or not).
However I’ve never seen it coming. It’s probably that extension. 
Lots of new exciting extensions! But let OpenGL 2.0 clean this mess!

Yeah, nobody has something to win on fragmenting OpenGL. GL_NV_vertex_program1_1 comes as a dissapointment for me, I was hoping nVidia would join up with ATi and Matrox on GL_EXT_vertex_shader, not going further in their own direction. This means I’m not sure I’ll be able to support nVidia cards in my demo/game/whatever I’m working on.
That will only happen in OGL 2.0… until there they are more interested in tring to make other companies suffer.
Have you seen this? http://www.pcrave.com/news/news.htm
among others:
GL_NV_draw_mesh void glDrawMeshNV (GLenum mode, GLsizei count, GLenum type, GLsizei stride, const GLvoid *indicesTexCoord, const GLvoid *indicesNormal, const GLvoid *indicesVertex);
Did they implement multi-index-array?
(despite Matt’s strong-scepticism he expressed few threads ago )
If it is, then it is quite poor in comparison to gl2.0’s solution, i think.
