Show HN: A raytracer to shade topographic maps in R
That's a cool project and a nice write up. I remember as a 13 yr old being fascinated by 3D software. I think I just wanted to create something photo-realistic with a computer. I couldn't afford 3DSMax, so started on the steep learning curve with Blender. About the same time, they integrated Yafray into Blender, resulting in some outstanding renders, similar in quality to commercial packages. I was amazed and started delving into the maths - what a fun and confusing journey it was! Five years later when the maths was finally explained to me at university, I truly appreciated the work that went into things like Blender and Yafray. So kudos to you for your raytracer!
