Two articles were recently put online, and they have a lot in common, so I suggest you read them both.
First up, “Science for CG” was originally a series of posts made on the cgtalk forums, and were recompiled for ease of reading by someone over at subdivisionmodeling.com. The result is a roughhousing of a lighting and optics physics textbook and a tips n’ tricks tutorial with glossy pictures. The explanation of BDRF with cubes is very cool.
Second, the shader artists who worked on the recently released Cloud With A Chance of Meatballs talk about how they’re expertise in the area of CG shading (like in the first article) combined with previous experience in photography made for a good match when it came to working in CG film.
Next post, I’ll be in Europe rubbing elbows with Blender geeks!
