Bare Bones Ray Tracing
Due: September 20, 11:55pm
For your first programming assignment you will implement a bare bones ray-tracer with the following capabilities:
- Ray-object intersection support for:
- Planes
- Spheres
- Triangles
-
Orthographic projection
-
Perspective projection with a movable camera
-
Multi-jittered sampling for the primary rays
- Simple shading using the Blinn-Phong or Phong reflectance model. Just do diffuse (Lambertain) shading without any specular component. Use a directional light with no position
Hand-in
You will hand in your code and 5 images:
-
One orthographic rendering of a scene with spheres and triangles
-
One perspective rendering of the same scene
-
An additional perspective rendering of the same scene from a different viewpoint
-
Two images illustrating the effects of using jittering. The first image should use a single ray for each pixel, while the second should use multi-jittering. Try to set up a scene so that the difference is apparent.
Hand-in will be done on Compass and detailed instructions will be forthcoming

Technical Details
-
You can use any programming /platform you wish
-
You can use any math library/package you wish to support the vector/matrix operations you need to perform
-
If you wish to use the framework code from Ray-Tracing from the Ground Up, you may.
Keep in mind that if you use code from other sources, you must document the use of that code
