A method and an intersection testing module in a ray tracing system for determining whether a ray intersects a three-dimensional axis-aligned box. It is determined whether a first c
So, I feel like an idiot and I'm losing faith in my ability to understand 3-D maths. I want to project a triangle from 3-D space into 2-D space. Sounds simple enough, just use a model-view-projection matrix. Got it, easy. However, I just don't seem to get a grasp on how ...
To answer your question about the intersection of a line and a circle, you have to start with the maths behind. Line and circle are defined by the following equations: y = a.x + b % Cartesian definition of a line (x-x0)² + (y-y0)² = r² % Cartesian defi...
