Document Summary
Chapter 12: geometric primitives result. z += (p >y + c >y) * (p >x c >x); // normalize the result and return it result. normalize(); return result; The best-fit d value can be computed as the average of the d values for each point: Imagine a plane and a point q that is not in the plane. There exists a point p that lies in the plane and is the closest point in the plane to q. Clearly, the vector from p to q is perpendicular to the plane and is of the form an. Figure 12. 15: computing the distance between a point and a plane. What"s surprising is that we can compute a without knowing the location of p. we go back to our original definition of q and then perform some vector algebra to eliminate p: Computing the signed distance from a plane to an arbitrary 3d point. Triangles are of fundamental importance in modeling and graphics.
