Hey guys! So I'm in my second semester in college learning C (Computer Science 102), and we're doing a raytracer. I'm having some difficulty understanding it all. I'm getting by, but it just seems like a huge step from 101. Should I be able to get raytracing easily, and is raytracing normally an easy thing? I feel like I'm behind because I don't understand it that well, at least right now. We're still in the beginning, but it's pretty confusing.
Thanks guys!
Building a ray-tracer isn't that difficult. Building one that's fast, well that is!
My implementation takes 10 minutes to render 100 polygons with 800x600 resolution...
( haven't added reflections yet :rolleyes: )
:D
I don't know what you find hard, the concept of how it works, the geometry and vector mathematics involved, or just how to turn the knowledge into a program.
Really, if you approach the necessary things one at a time and learn them, then putting it all together is not too bad. In fact writing a raytracer is probably the most personally rewarding programming project that you can do. You can create some fantastic looking images with barely a few lines of code.
Anyway, there is always something you can make a start on, and something that you can mention which you believe you know the least about. Give us something to go on and we'll happily help you. Right now about the most we can do is ask that you turn to your favourite search engine.
Hi,
I found this via google. I Just skimmed through it but it looks like a good tutorial
