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

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,
