Hello, I'm trying to debug why fbo-copyteximage-simple is failing, and I'm... failing. It's an extremely simple test. I'm pretty sure that the copyteximage part of it has nothing to do with the failure, at least it behaves identically when I just return tex instead of copiex_tex. Without any modifications, the test just renders one big red square. I think there's something

...olor3f(0, 0, 1); glVertex3f(128, 0.75*128 + 128, 0); glEnd(); Then all is well. However if I do: float verts[3][6] = { { -0.6*128 + 128, -0.75*128 + 128, 0.5, 1, 0, 0 }, { 0.6*128 + 128, -0.75*128 + 128, 0, 0, 1, 0 }, { 128, 0.75*128 + 128, 0, 0, 0, 1 }, }; glVertexPointer(3, GL_FLOAT, 24, verts); glColorPointer(3, GL_FLOAT, 24, &verts[0][3]); glEnableClientState(GL_VERTEX_ARRAY); glEnableClientState(GL_COLOR_ARRAY); glDrawArrays(GL_TRIANGLES, 0, 3); glDisableClientState(GL_VERTEX_ARRAY); glDisableClientState(GL_COLOR_ARRAY); Then I see the failure. Looking at...

Hi, for example, if I have glVertex3f(0.75, 0.75, 1.0) how the video card processes these three floats? Does the card work with floats? Does (mesa? gallium? driver?) process these three input floats before it is sent to the card? Where is the code for it? If you say the floats are memory mapped as in exec->vtx.buffer_map = (GLfloat *)ctx->Driver.MapBufferRange(...) I would say from what I

The vbo module converts this to the equivalent of glGenBuffers(1, &buf) glBindBuffer(GL_ARRAY_BUFFER, buf) glBufferData(GL_ARRAY_BUFFER, ...) foo = glMapBuffer(buf) write vertex values to foo glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 0, 0); draw Hope that helps, -ilia

This patch series adds the needed support for this extension to the various parts of mesa to finally enable it for nvc0. Dave Airlie (1): glsl: lower cull_distance into cull_distance_mesa Tobias Klausmann (10): glapi: add GL_ARB_cull_distance mesa/main: add support for GL_ARB_cull_distance mesa/prog: Add varyings for arb_cull_distance mesa/st: add support for GL_ARB_cull_distance
