The enumext.spec in the registry says:

but I don't see that file in the registry anywhere.

At some point (around 3.2 maybe?), the .spec files stopped having version numbers and 'last updated' dates (they used to be in a passthru: in enumext.spec). Any chance of getting those back in some...

How does the ARB_compatibility extension work?

If the extension is supported, a 3.1 context has all the deprecated stuff still there anyway? Or does an application need to explicitly request...

Using 177.89 drivers in gl3 mode, glBindRenderbuffer seems to only accept renderbuffer names which have been returned from glGenFramebuffers instead of those returned from glGenRenderbuffers.

for...

Do newer drivers have any GL3 support?
I'm trying the 178.13 released yesterday, but not getting WGL_ARB_create_context in the WGL extension string or any other sign of it working, even with it...

Trying to narrow down a list of extensions which are still relevant when using a gl3 forward compatible context.

So far my list is
ARB_draw_instanced ARB_geometry_shader4 ...

ok, http://www.3bb.cc/tmp/vao-exit-crash.zip is a binary of previous program chopped down to just the exiting with vao bound bit:


#include <stdio.h>
#include <GL/glfw.h>
#include "glext.h"
...

Found 2 possible bugs with the 3.0 VAOs in the 177.89 drivers:

Main one is that calling glDisableVertexAttribArray(1); with no VAO bound breaks any existing VAOs that had attrib 1 active with a...

in 4.2 WHOLE FRAMEBUFFER OPERATIONS, page 262(page 278 of the pdf)

ClearBuffer{if ui}v( enum buffer, const T *value );

lacks a return type.

Now that we have some beta drivers to play with, any ETA on current .spec files? The ones at http://www.opengl.org/registry/ just add enums, no new functions as far as I could tell.

(or even full...

The new .spec/.h files also seem a bit short on new functions...

try random #s up to 65535 instead of 255?

Is there any canonical set of machine readable info on function signatures, enum values, etc. for OpenGL and extensions?

Closest I've found so far is the *.spec files from oss.sgi.com , but...

in the vertex program, use
state.texgen[n].eye.{strq}, state.texgen[n].object.{strq}, and the equations in the GL docs under "Generating Texture Coordinates"(2.11.4)

untested code off the top of...

My point was that you get the same results whether the geometry came from a reflection or from independent geometry, and if it's correct for independent geometry, its correct for the reflection case...

Yeah, that was what I meant about the GL_ARRAY_BUFFER stuff, but like I said before, it should work either way...

Tried running your original code, and with GL_RGB32F_ARB in the ReadBuffer call, I...

I think you must be getting the angles wrong in your diagrams...either method should give you correct results.

Think of it this way:
You have a scene. It is lit correctly.

Now put a wall with...

I meant just do the BufferData() using the VBO instead of the PBO, not dropping PBO completely. Looks like the PBO examples do it the same way you did though, so that should work...
Only other...

Possibly try GL_ARRAY_BUFFER instead of GL_PIXEL_PACK_BUFFER_EXT?
Also, you might want GL_STREAM_COPY instead of GL_STATIC_DRAW, but that shouldn't make it crash.

If I read correctly, you aren't actually doing a texture atlas, so you don't need any complicated math in the shader. Seems like setting GL_CLAMP_TO_EDGE and then using a shader to chop off just the...

try changing fragment program to:
MOV result.color.rgb,fragment.texcoord[1];
MOV result.color.a,{1,1,1,1};
(or set result.texcoord[1].w in the VP)

do 76.41 drivers have working stencil renderbuffers yet? or mipmap generation on cubemaps?

try the arb FP extension: GL_RGBA32F_ARB, GL_RGBA16F_ARB, etc. Those are what I've been using, and they work for me...hmm, looks like those are actually the same value as the ATI extension (and apple...

Also, unless you have a very unusual monitor, you can't actually display 40,000x1000 pixels at once, so you might consider streaming the data. It would mainly help with the loading part, but breaking...

simple example : (with no error checking, etc. in particular, should check # of valid attachments and draw buffers, currently 4 on my 6800GT, dunno about older cards. Also, verify the framebuffer is...
