Agreed, DSA is the best thing that happen since ... GLSL!Originally Posted by Jan
It's amazing to see how small is the subset of the API can become when you use all those great extensions DSA and bindable buffer.
I think, it would be so great to have a simplified API but those days what I really waiting for is:
1 - bindable buffer ♥
1 - DSA ♥
3 - a debugging profile
Second that list.
On the debug profile, I would like to see something similar to d3d10's infoqueue. Basically it's just a context wide info log the driver can dump messages, performance tips, warnings and errors into. This comes in awfully handy.
Out of curiosity, which vendors support DSA? For me, this is the single biggest reason to move to GL3 (everything else is the same old mess as GL2.1).
Afaik, currently only NVidia on GF8x and above.
DSA is not part of GL3. It is written to take into account the fixed function pipeline stuff like glMatrixMode

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
Just to touch on some of the items mentioned above -
conditional rendering - this is in GL 3.0 already. Shipped.
buffers for uniforms - you will see something in GL 3.1 in this area.
"mixed FBO formats", there are some things that are relaxed under GL3 and GL3 capable hardware - it would help if you could elaborate on the usage you have in mind (see http://www.opengl.org/registry/specs...r_object.txt).
Geometry shader - not in the core spec in 3.0, only a shipping extension on NV at the moment. An ARB-neutral version of the GS extension has been posted here: http://www.opengl.org/registry/specs...ry_shader4.txt
I'd like to see a lot of the DSA concepts in GL as well. It's a topic that has a reasonable level of interest in the working group.
Custom resolve for multisampling, thanks for pointing that out.
(edited per correction regarding GS on AMD HW)
No, AMD has no support for geom shaders in 9.1 driver.
I appreciate the correction, will ask them about that.No, AMD has no support for geom shaders in 9.1 driver.
I gather it won't be in core GL3.1, either? Any chance we'll see an implementation outside nvidia any time soon?DSA is not part of GL3. It is written to take into account the fixed function pipeline stuff like glMatrixMode
If enough people make a big enough stink about it you bet your boots we'll see it ;-)
