Project Proposal: A Toon Shader

·      Title: Create Toon Shader to Achieve non Photo-Realistic Rendering.

·      Student: Robert Marinaro

·      Class: Computer Graphics II: 4003-571

·      Professor: Reynold Bailey

·      Project Website http://rjm5199.blogspot.com/

·      Project Objective:

o    This Project’s goal is to create a Toon Shader for non-photo realistic rendering using prman shading language and OpenGL.  This area of the pipeline that the project will focus on the processing of the scene.

·      Project Objectives

o    Learn prman

o    Write shader for NPR
 

·      System and Software

o    Hardware: PC running Windows Vista with a NVIDIA 8800

o    Software: prman, OpenGL, GLUT

·      A breakdown of project components, e.g.:

o    The end result will be a simple scene in OpenGl rendered in the Toon Shader.

·      Project Responsibilities:

o    Learn prman

o    Write Toon Shader

o    Build 3D scene         
         

·      Project Timeline:

o    Week 5: Learn prman

o    Week 6: Write algorithm for NPR

o    Week 6-8: Code Algorithm complete

o    Week 9-10: Wrap up Project

·      Final Presentation:

o      Show scene without NPR

o      Show Slides showing various step taken to implement shader and algorithm.

o      Show Scene with NPR

Checkpoint 2: The Camera

This is a scene I displayed by tracing rays, using the coordinates received from checkpoint 1. 

Checkpoint 1

I used OpenGl for the initial checkpoint. The scene is divided into several objects. 

This scene has three visible objects:

• Two spheres
• The floor

In addition, there are two objects which are not directly visible:

• A point light source
• A camera

Here are the the parameters of the following scene. 

Camera:

Position: x= 0.0, y= 0.0,  z = 10

Look At: x=0.0, y= -1.0, z = 1.0

Up: x= 0.0, y = 1.0 , z = 0.0

Near Clip: 1.0

Far Clip:  500

Aspect Ratio:  4/3

Light:

Position: x =  5.0, y = 10.0, z = 2.0

Diffuse = 1, 1, 1

Ambient = 0, 0, 0.1

Green Sphere: 

Position: x = -2.5, y = -2.5,  z = -2.5

Radius: 2.0

 

Yellow Sphere:

Position: x = 0.0, y = -0.5,  z = -0.5 

Radius: 2

Plane:

Upper Left Coordinate: x = -8.0, y = -4.5. z = -20.0

Upper Right Coordinate: x = 5.0, y=-4.5. z= -20.0

Lower Left Coordinate : x = -8.0, y=-4.5. z= 15.0

Lower Right Coordinate: x= 5.0, y=-4.5. z= 15.0

Assignment Information

The Ray Tracer Programming Assignment is divided into Seven

 Checkpoints:

1. Setting the scene
2. Camera modeling
3. Basic shading
4. Procedural shading
5. Recursive ray tracing - reflection
6. Recursive ray tracing - transmission
7. Tone reproduction

This is checkpoint #1: "Setting the scene".

The ultimate goal of these assignments is to reproduce the classic ray traced image from Turner Whitted's 1980 paper:
