Ray Tracing Lab

Lab Goals:
By the end of this lab you should:

·  Understand how ray-tracing works to represent three-dimensional images

·  Understand how to use POV-RAY environment and language to represent three-dimensional scenes

·  Understand how to incorporate the X-, Y-, and Z-axis into a vector-based image 

Due Date:  Tuesday, 04/03/01

Directions:

1.     Using POV-RAY, create a scene that includes a simple sphere with a plain color texture.  Save your image as mySphere.pov and upload it to your Phoenix account. Additionally, find the rendered Windows Bitmap (most likely found in C:\POVRAY_IMAGES\ directory) and upload it to your Phoenix account as well.   See POV-RAY resources below for more information on how to use POV-RAY and on Ray Tracing.

2.     Using POV-RAY, create a scene that includes a simple cube with a plain color texture.  Save your image as myCube.pov and upload it to your Phoenix account. Additionally, find the rendered Windows Bitmap (most likely found in C:\POVRAY_IMAGES\ directory) and upload it to your Phoenix account as well.  

3.     Using POV-RAY, create a scene that includes a simple cone with a plain color texture.  Save your image as myCone.pov and upload it to your Phoenix account. Additionally, find the rendered Windows Bitmap (most likely found in C:\POVRAY_IMAGES\ directory) and upload it to your Phoenix account as well.  

4.     Using POV-RAY, create a scene that includes a simple cylinder with a plain color texture.  Save your image as myCylinder.pov and upload it to your Phoenix account. Additionally, find the rendered Windows Bitmap (most likely found in C:\POVRAY_IMAGES\ directory) and upload it to your Phoenix account as well.  

5.     Using POV-RAY, create a scene that includes a no less than three different objects.  Your scene should include at least one plane. Experiment with more than one texture (at least two of your textures should not be plain color textures!).  Save your image as myScene.pov and upload it to your Phoenix account. Additionally, find the rendered Windows Bitmap (most likely found in C:\POVRAY_IMAGES\ directory) and upload it to your Phoenix account as well.
