Daniel, For doing 3d modeling of the structures, blender is a good choice: https://www.blender.org/
There's lot of options for how to do the ray-tracing, it's been a staple of computer graphics for a long time.
To help you get started: https://en.wikipedia.org/wiki/Ray_tracing_(graphics) https://developer.nvidia.com/discover/ray-tracing https://developer.nvidia.com/rtx/ray-tracing HTH, Matt On 1/29/2022 6:09 PM, Daniel C. wrote:
Hey gang, I'm tilting at a windmill called "simulated evolution," and I'm in over my head before I've even started. I want to have plants and animals co-evolve, and plants obviously need to grow up toward the sun, getting more or less nutrition depending on how much of their photosynthesizing surfaces are exposed to sunlight. Which means I need a way to represent 3d structures, and then calculate which of them can be seen from above. (The first iteration won't include orbit or rotation of the planet, so no sunrise / sunset and no seasons.) I have absolutely no clue what data structure to use for this, and what algorithm is appropriate for doing the projection that calculates sun exposure. Help? I'm just looking for the names of the appropriate tools, I can teach myself to use them. Thank you!
