CRay Blog

Hi all.

I have worked on C-Ray a bit more in the past weeks, and I made it compatible with Windows 7. So it should be able to run on any Windows 7/10 machine now. Another thing is that I have completely replaced the underlying OpenGL code with d3d11 code. I find d3d11 a lot stricter and harder to make mistakes with than OpenGL, so I will go with that in the future.

I have cleaned up code a bit and open sourced it on github, you can find a link to it on the project page. The only caveat is that "Buddah" model is not on the repository because github apparently has a problem with big files. Anyhow, the code is completely public now!

Finally, the technical bit. I haven't done much in terms of the path tracer itself, but I have added a simple thin lens model which gives decent depth of field. By default, C-Ray automatically adjusts focal distance based on the center pixel's depth, but you can change that in control panel. Anyways, here is the new list of requirements:

OS: Windo

Demo!

Hi guys, it’s an honor to have CRay be featured on the handmade network. The project is accepted earlier than I anticipated, so I scrambled to make a (hopefully) good-enough demo for people to play around with. Here it is:

CRay Demo

Now I will provide a short tutorial on the basic controls and what you should expect to see. Keep in mind that it is very likely for there to be a bug in CRay that is only triggered on certain machines (it’s OpenGL, after all). So if you see any unexpected error messages pop up, please report them to CRay’s forum as it will help me to identify these bugs and make CRay more robust.

Requirements

Windows 10 (will work on compatibility later) At least OpenGL 4.4 At least 2GB of memory (as for now, will be improved on this later)

Tutorial

Upon startup, you should be greeted with a monkey, like this:
