CSL781 Assignment 2

Due: Mar 14, 11pm. To be turned in on Moodle.

OpenGL Graphics

In this assignment, you will replace the raytracer of assignment 1 with OpenGL Pipeline. The scene will largely be the same as before, with the following changes:
  1. The area light source is removed. Shadows, object reflection and ray refraction are not required.
  2. Floor is not reflective, but it is tiled (you may find any texture image from the web for the tile).
  3. Table top has a wood texture (you may find any wood texture image from the web).
  4. Glass should remain translucent.
You should convert all geometry to triangles offline by yourself, and save them in a single file. Use the following format:

<Object_count: %d>
*** for i in (0..Object_Count]
<Matrix_i: %f %f %f %f %f %f %f %f %f %f %f %f >
<Object_i Vertex_Count: %d>
*** for j in (0..Objec_i_Vertex_Count]
<Object_i_Vertex_j X Y Z: %f %f %f>
<Object_i_Triangle_Count: %d>
*** for j in (0..Object_i_Triangle_Count]
<Object_i_Triangle_j %d %d %d>
Devise a generic reader for your scene. Separate from the primitive file, you may also read the object's illumination parameters from another file.

The interface will adapt as well:

  1. No area light movement.
  2. The movement of camera will be by mouse. Left-Right motion moves on lattitude, Up-Down on Longitude, and Diagonal motion combines the two.
  3. The radius of the sphere on which the camera moves can be reduce with up arrow and increased with down arrow -- simulating forward and backward motion, respectively.
