Introduction

General description

• Continue to develop the ray tracing program you started in the last assignments. Your scene will again consist of 2 or more opjects, with each given by its
  • type: sphere, plane, polygon, quadric
  • defining spatial data:
  • sphere: center (x, y, z), radius
  • plane: point, normal vector
  • polygon: list of vertices in 3-space
  • quadric: list of coefficients? or type and relevant information
    e.g. cylinder, point and vector (or two points) to define the axis, radius
  • color (R, G, B)
  • texture, none or which map (one available map is enough fo this project)
  • bump, none or which function, try one on a plane, one on a sphere
  • coefficients: k_a, k_d, k_s, k_t (ambient, diffuse, specular, transmitting).

• At least one of your spheres must be reflective to show the reflection of you planar textures and bumps.

• At least one of your spheres must have a bump map.

• At least one of your planes must have a texture map.

• At least one of your planes must have a bump map.

Due

Grading

For the performance parts of this program:

• polygons - 30 points; (planes but not polygons - 20)
• bump map on plane - 15 points
• bumpmap on sphere - 15 points
• texture map on plane - 15 points
• Quality of your image(s) - 10

Turn in:

• your source code. Your code should be well organized and commented.
• a makefile, if necessary.
• a README file containing:
  • your name, the date, and the assignment number
  • a list of the files in the folder with comment for each explaining its purpose
  • instructions on how to run your program
  • a description of any bug that you have not been able to fix. A documented bug will not cost you as much as an undocumented one.
  • You may include data files for up to three scenes.
  • Please do NOT email ppm files or executable code. I will generate them from your source code.
