This program doesn't need anything particular to get compiled. Take a Linux shell and type the following command where your file lives: 001 c++ -O3 -o raytracer raytracer.cpp To create an image, run the program by typing ./raytracer in a shell. Wait a few seconds. When the program returns, you should have a file called untitled.ppm on your disk.

c) and radius R can be represented as: (x-x. c) + (y-y. c) + (z-z. c) - R = 0 For a point pon the sphere, we can write the above in vector form: (p-c). (p-c) - R = 0 (note ‘.’ is a dot product) We can plug the point on the ray p(t) = e+ t d. (e+td-c). (e+td-c) - R = 0 and yield (d.d) t + 2d.

Creating a ray: • Origin is eye • Pick direction to pierce centerof pixel. Whitted-style Ray Tracing. • Turner Whitted introduced ray tracing to graphics in 1980 • Combines eye ray tracing + rays to light and recursive tracing • Algorithm: 1. For each pixel, trace primary ray in direction Vto the first visible surface. 2.

Ray Tracing in the real world Light is emitted from light source Bounces off of the environment Assumptions Light travels in straight rays Path of light changes based on object interaction. Can simulate using basic geometry. Some light will reach and be focused by camera onto film plane. Lots of light will not!

If c0 - c1 defines an edge, then we draw a line from c0' to c1'. If c0 - c2 defines an edge, then we draw a line from c0' to c2'. Figure 2: projecting the four corners of the front face on the canvas If we repeat this operation for remaining edges of the cube, we will end up with a two-dimensional representation of the cube on the canvas.
