Hello list,
I'm currently working on a Gem patch where I have a lot of sphere
primitives and I would like to identify the sphere that appears
under some particular Gemwin screen coordinates (aka raycasting).
I can't find an object that already does this calculation so I ended
up finding this SO answer explaining the raycasting principle
https://stackoverflow.com/a/19153090.
Still, I'm a bit lost and don't know where to start ... I found this
informative post for the 3D graphics noob that I am :
https://gamedev.stackexchange.com/a/178645
But I can't figure out how to apply this to Gem.
Any help would be greatly appreciated.
Best,
Joseph
