Hello,

In 3D, say you have a triangle defined by three non-aligned points (A,B,C).

How do I find out if the projection of a fourth point onto the plane that the triangle belongs to is inside the triangle?

Hello, I'm trying to make a 3d online game in a sci-fi environment. I've finally got the connection set up, but I'm not shure how I'm going to handle the planets.

I'm planning to make the planets very large to make the game more immersive, leading to the problem that loading something that size into memory at once will probably make something horribly go wrong.

In Minecraft, the worlds are also huge, so they are divided into 16x16 square "chunks" that are loaded when approached by the player and unloaded and saved as he or she moves away from them. I'd like to apply a similar system to my planets, but there's one difference: Minecraft worlds are flat, planets are spherical. How do you divide a sphere into "chunks" without things going crazy around the poles, heightmaps becoming deformed, etc... ?
