Err, the distance between two Triangles, not two points on a triangle. The distance between two triangles will change as a function of time. So I intend to set the distance to 0 and solve for time to see when their trajectories will touch.

Oh, polygon implies triangle =/ (i'm not a math person- sorry). Most of those systems use a corrective technique, and focus on efficiency. I'm focusing on precision and prediction, which is not very efficient. Advanced techniques use a convex hull through minkowski addition, I don't...

ah, I've figured it out by now. I just derive the Tangential Velocity from Angular Velocity and add it to the Linear Velocity- which makes up an Aggregate Velocity. That Velocity * Time + Position of a point = Position of that point at Time. Thanks.

I was just wondering, is there a way to write a polygon as an equation in 3d? (Yes, a polygon, NOT a polyhedra) It's intended to be a part of a collision detection program, so I need to be able to represent all points on a given polygon as an equation. Each polygon is being acted upon by...

Heheh- yes, it's full 3D, and I'm working with irregular polyhedrons (genuses, concavity, everything, except soft bodies and inertia tensors, I don't want to break my brain yet). Apparently there is some trick to it, I had someone explain it to me, but my angular velocity is being scaled by...

Could burning fossil fuels alter the density? In a sense, slightly reducing gravity over time? If so, that would eventually have a huge impact on solar energy absorption, no?

The only way to 'truly' determine when an object collides is by plotting every point on it's surface as a function of time between an arbitrarily small amount of time, and comparing the same with another object. If an object is spinning, any given point on the surface of a rigid body will...

Hi, I have a little problem. I recently got the nerve to try and teach myself all of the physical properties necessary to program a physics engine (the insomnia is a DIFFERENT problem). It's going much better than I could've hoped (considering I started a few days ago). My knowledge of physics...
