Cheap Reflections

[kalango]

Hello community, here is a simple project that i worked for about 2 hours. Its a cheap reflection fx, its composed of a camera render map and a sphere mapping material. You also might want to adjust the projector camera FOV so it can fit your needs better.
It was tested on a PC only, but it should work on any architecture that supports rendermaps.

Feel free to change it, improve it, etc...

PS: some artifacts are spotted if the model is a bit convex like the monkey model included, the camera sees the model polygons and plot them as black artifacts.... Adjusting the camera near plane should do the job.

PPS: If you change "MDL_Sphere" for "MDL_Monkey" in the main AI you will be able to test the example wih the monkey head model.

very nice effect great share thx.

looks nice.
but rendermaps are not cheap! sphere maps are.

Thanks!
The "cheapness" is more related to the simplicity of the effect. Also if you see the cubemap technique as rendermap projections into one model, the effect i proposed is definitly way more optimized. Even dual parabloid techniques are heavier than this.

Thaks anyway.
