This assigment involves making a ray tracer capable of ray tracing spheres
and triangles with basic shading from a given camera position.
Percentages indicate percentage value for this assigment.
Render at least one image demonstrating all the effects below.
Send source files (all .cpp, .h and makefile - not object files) as well
before the deadline.
Task 1: Camera transformation: 15 %
Implement tracing of primary rays given a camera with a location, view
direction, field of view, up vector, as well as an image of a given resolution.
Task 2: Sphere intersection: 15 %
Implement a sphere object with intersections and normal computations. The
sphere should be implemented such that the center and radius are parameters
that can be changed.
Task 3: Triangle intersection: 20 %
Implement a triangle intersection routine that computes the intersection of
a ray and a triangle (specified as three vertices).
Task 4: Barycentric interpolation: 15 %
Implement barycentric interpolation of normals for a triangle with three nor-
mals (one per vertex).
Task 5: Implement a material with diffuse shading and specular
highlights: 15 %
Implement diffuse and specular shading.
Task 6: Implement specular reflection for the material: 10 %
Add mirror reflection to the shader.
Task 7: Implement shadow rays to get cast shadows: 10 %
Implement shadow rays to compute shadow regions in the model.
