Today, while I was thinking of the best implementation solution for the vector operations, I realised that I am just not motivated by writing a raytracer in Forth. I’ll have to find something more interesting, or at least, more Forth minded to work on.
If I want to raytrace, better to improve the Lisp raytracer, which is sitting idly in my Code/Lisp folder. Steps that will follow in the raytracer path:
Code commenting: I almost forgot how the main loop was rolled
Performance: ditch temporary image matrices and output straight RGB data. This means no antialiasing, out of the box without some tweaking. But I can tweak that with Monte Carlo methods
New objects: Where are my triangles? I only have spheres. I need triangles, and triangle meshes.
Triangle mesh importer: from a nice ASCII format generated by some open source program
Transparency: My previous version had it, this new one, does not.
If you have any other suggestion for a Forth project, leave a comment here or in Reddit. Thanks!
