This was for a college assignment in my undergrad graphics course. The goal was to write a raytracer in C that could render a simple scene with some objects. The code dates from April 2013. It uses legacy OpenGL to draw the rendered scene to a viewport.
This was developed on OSX and Linux, and can only be run on those OSes (because of the OpenGL headers).
makeWhen you have built the program, run it with the parameters (see below).
./raytrace eyeX eyeY eyeZ atX atY atZ recDepthYou should be able to see a scene with a checkerboard floor, snowman, with a light illuminating the scene.
| Parameter | Description |
|---|---|
eyeX |
The X position of the camera. |
eyeY |
The Y position of the camera. |
eyeZ |
The Z position of the camera. |
atX |
The X coordinate specifying the direction the camera is looking at. |
atY |
The Y coordinate specifying the direction the camera is looking at. |
atZ |
The Z coordinate specifying the direction the camera is looking at. |
recDepth |
The recursion depth for reflective objects in the scene. |
Reflection with a high number of recursion levels tends to have black dots appear at reflections. I wasn’t exactly sure why this was happening. I tried adding blocks to prevent burned out whites, but this did nothing. This doesn’t occur if the max recursion level is 0.
