Java Ray Tracer – Just a test

July 6, 2012 - 2:46 pm by Joss Whittle Graphics Java

A few months ago, inspired by our Graphics Course, I decided to write a Ray Tracer. I had written one once before, in C# of all things, the summer before starting university. But it was crude and took 3 minutes to render one sphere, incorrectly too… I knew I could do better. Here is the result of 3 days worth of playing around with Java between lectures.

I didn’t quite get triangles working at the time. It was an issue to do with Java’s implementation of floats not having enough precision. My next Ray Tracer will be in C++ so that shouldn’t be a problem. (I know… A bad programmer always blames his tools…)

Here are some other choice renders…

First Person Pac-Man (Pseudo-3D Game)

Thought I’d move some posts over from the L2Program Blog.

This was my first major project of this summer, the second being this site. The idea was to create a Pseudo-3D rendered game like the classic Wolfenstein3D.

This style of rendering takes a 2D world and “fakes” 3D by making things further away from the camera shorter in the middle of the screen.
