Hey, all,
Is there any way to use a colour projector as essentially a torch? I want to be able to project a colour image onto a wall, and be able to move it’s location my moving the projection point of origin or angle.
At the moment when I try this, the projected image just snaps to the UV’s of the target object.
There must be a way to overcome this?
Cheers,
SB
sounds like you want decals, not a projector, as you need additional geometry to cover for “large stretched” areas where the projector would fail (also the projectors are very costly, each hit object is redrawn)
Naturally if you want to light all in the beam basically, projectors are the only way to go aside of pixel light with cookie (OpenGL ES 2.0 hardware will be a must anyway, just due to the load you are likely going to push onto them, even if you run it in ES 1.1)
