为什么会显得不稳定？我从 Apodaca 的那本《Advanced Renderman》里完全没看出这种感觉。看起来是个很酷的地方，只是后来在 Lucas 和 Jobs 之间做了一些人员调整。我一直纳闷为什么 Pat Hanrahan 在皮克斯没那么出名……后来我搜了一下他。才发现原来他……
Why did it seem unstable? I didn't get that impression from Apodaca's book: Advanced Renderman. Seemed like a really cool place with a bit of shuffling between Lucas and Jobs later. I always wondered why Pat Hanrahan wasn't more prominent in Pixar... then I looked him up. I haven't realized he…

Yes, classic book where from 90's like "The Renderman Companion" or "Advanced RenderMan", and then there is toolings books, for each tool. I used to own many Maya books and 3DS Max books.

是的，像 90 年代的经典书籍《The Renderman Companion》或《Advanced RenderMan》，然后还有工具书，每个工具一本。我以前收藏过好多 Maya 和 3DS Max 的书。

……在《虫虫危机》中，对 BMRT 的调用被用于蝗虫老巢里的玻璃瓶。所有其他的反射和折射都是用“标配”的环境贴图搞定的。来源：Apodaca, Gritz, 《Advanced Renderman》——MK 2000。

……在90年代及之后，很少有人写着色器（shader，大部分是用于视效 VFX，用 RenderMan SL 写的）。所以除开《Texturing and Modeling -- A Procedural Approach》、以及《The RenderMan Companion》和《Advanced RenderMan》之外，根本没什么参考资料。后来的《GPU Gems》系列填补了一些空白。RenderMan Repository 网站当时存有着色器源码，所有的 pattern 都是隐式的（也就是我们今天说的 2D SDF）……
