Creates photorealistic images via ray tracing

https://github.com/johsteffens/actinon

Renderings look fantastic, but the program is done in C.

I wonder how hard it would be to convert to Lazarus?

Also found a basic Raytracer for Lazarus that renders to a ppm file.

SaguRaytracer

A tiny cross-platform object pascal raytracer

DZandaa, there is also a Delphi GLScene 3D-Terrain-Programming a bit
like your 3D one
https://github.com/jseling/3D-Terrain-Programming
Also the SaguRaytracer might possibly go well with your obj loader
that you were working on?

Hi Eddie,

Ray tracing reminds me of my first ray tracing program, written in C
on an Amiga 2000, where I was happy to see three spheres: matte,
metallic, and transparent, with shadows  It took about an hour to get
a result , now I use ZBrush with Cinema 4D, Poser and Octane render.
About 2 minute to render a complete scene with light, sky, plants,
etc...

Or I use AI, but that's not fair.

hard it would be to convert to Lazarus? I spent some time a couple of
years ago, looking at converting a C ray-tracing program (rayshade),
but I found that I had forgotten most of what I once knew about C, so
the task was beyond me.

So, *I think* it is probably possible to convert the program to
lazarus, but it would be a lot of work and you'd need to be a skilled
C programmer... (imho).
