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

...ing the 3D fencing mechanism. It seems we might be better off always putting vertex buffers in VRAM, since the blob does so and while writing to them might be a bit slower, the required synchronization may be even worse. I attached a renouveau test for GL_NV_vertex_array_range and one for all the glBufferData flags. The quality of the code is quite low but it should do the job. -------------- next part -------------- A non-text attachment was scrubbed...
