We are using point sprites to render icons in our 3D scene, because it’s much easier and more efficient than traditional billboards. Unfortunately I’ve just realized that there’s an implementation dependent maximum size for points. In our case it seems to be 64x64 on the GF6600. Now, this is probably big enough for particles, but it’s a severe limitation, when using point sprites to render hi-resolution icons. I’m wondering if there’s any reason for such a limitation?
Is this something that can be changed in the driver or is this a HW limitation? Do we have any chance of seeing larger points on this HW any time soon? (BTW: we are using non-antialiased points)
PS: I’m not sure if posts like this should go in the advanced forum, but I don’t know where else? Maybe we should have a forum dedicated to driver/hardware/support questions?
