Off Topic / math smart guys help me out: finding if point is inside polyhedron
« on: March 31, 2018, 02:07:51 PM »
im not good at math so i need help.
i got a polyhedron (probably a circle, or a cone or something) and i want to check if a 3d point is inside that shape.
how do i find if a line intersects a 3d face? im going to use that and see if a vector cast from the 3d point intersects a certain number of faces of the polyhedron, to check if its inside. but i dont know how to calculate if a line intersects a 3d face.
some smart math people help me. please explain it in math formulas and expressions and stuff and give variables descriptive names other than A or B
