transform & lighting

Recommended Posts

I was wondering how to make sure my 3D applications use hardware TL. I''ve read the technical papers at the nvidia site and what I understand from them is that the gpu has taken over these two tasks from the cpu. What I was wondering now is that if I use OpenGL or Direct3D to do my transform and ligting calculations, will they automatically use hardware TL or not? I think it does, since they said old games automatically go faster but I''ve also heard of games ''fully using the hardware TL capabilities of a card'' or is that just vendor-talk? tnx in advance. jigr

I´m not sure older games automatically use T&L.

In DX 8.0, to use T&L you have to create the device with the flag called something like HARDWARE_VERTEX_PROCESSING...

Not sure about Lighting, BTW it is not used in games...

What the hells!

If you use OpenGL, and the card do T&L hardware, you''ll use it.
Nothing special to do.

OpenGL is well designed from the beginning.
