I think the collection of meshes that used to be at Williams is now here:

Re: Float versus double
I should say I haven't really run into any issues yet, I was just starting to feel like things were a bit messy, and I had a lot of redundant functions for different types in, for example, my vector class. I really wanted to make most of my code more type-agnostic. After some more searching, I see t...

Re: Float versus double
I think I'll make this into one or more switches. Thanks for both your replies. I've experienced precision issues in the past with objects far from the origin, or very strange in scale. It will be good to have a way to test the difference in quality and speed. I think this is an interesting question...

Float versus double
I have a mix of float and double types in the c++ code for my path tracing renderer, and I was just considering making things more consistent. I hear from a Google search that pbrt uses a compile switch. Double seems convenient for large scenes and for avoiding precision issues in arithmetic. But po...

Re: Request: Old Ashdown radiosity scenes
Thanks for the reply.
I found a zip of the floppy, but it only has room.wld on it. Maybe he had some scenes he didn't publicize for one reason or another.

Request: Old Ashdown radiosity scenes
Hey everyone- I'm working on resurrecting a hemicube radiosity renderer I wrote a long time ago. My reference at that time was "Radiosity, A Programmer's Perspective" by Ian Ashdown. He included a scene room.wld with the book (render attached). But the book also mentions others, like a cornell box c...
