Assignment №4: Monte-Carlo light evaluation.

0. Download hdr cubemap from HW4 into ./Assets directory.
1. Open scene Scenes/5_Cubemap. You should see three reflective spheres above a grass field.
2. Edit shader Shaders/cubemap.shader and implement Monte-Carlo evaluation shader for a given BRDF (GetSpecularProbability) by normal.
3. Reproduce
4. Send me a screenshot of your results at [email protected].
5. The e-mail should have the following topic: HSE.CG.<your_name>.<your_last_name>.HW4

Bonus points: You can get an extra 10% bonus if you use some kind of importance sampling.

Note: You don't have to make it fully realtime. Just make it somewhat interactive and keep the minimum noize from Monte-Carlo integration.
