Built in raytracing?

Question

Regarding this question, I was wondering if .NET has any libraries (or functions) that I can use to detect if one point collides with another.

I'm not sure which angles I should use, but is there any function like this

func(point src, rect target, angle, distanceOfVision, listPointOrRectOfWalls)

Pretty unlikely, but I don't know the formula or how to start. Its a quick and dirty prototype. I am thinking of writing a func function, but reducing the angle, making the line of sight a rectangle and checking to see if there are any wall points between src and target.

Answer 1

I would solve the problem as such:

• , .
• , : source_point + direction_vector * t. t = 1, , .
• : http://en.wikipedia.org/wiki/Line-plane_intersection
• , .
