In order to get peak performanse from my gfx card, I’ve placed each object of my scene into separate display list. Since objects had to be hierarchicaly connected I have used different display lists to represent object relationships.
Each of these lists has following form:
glPushMatrix();
glMultMatrix(motion_matrix);
glCallList(drawObject);
glCallList(callSubObject1);
glCallList(callSubObject2);
…
glPopMatrix();
To create motion I have been changing these matrices/display lists for each frame.
Is it possible that frequent changing of display lists leads to gfx card memory fragmentation, thus slowing down the process more than if I had done this ‘by hand’?
What performanse increase can I expect from VectorPointers and VectorArrays? Is it worth implementing? (I have single WindowsXP machine w/ ATI Radeon 9000ProII 128Mb)
Thanks in advance,
Vlada
