reverseBilinear

public static Vertex2D reverseBilinear(Vertex2D point,

The vertecies in quad need to be in order such that the first vertx is 0,0 in the texture the clockwise around

see http://iquilezles.org/www/articles/ibilinear/ibilinear.htm

Parameters:

point - point to get the uv of

quad - where the point is

Returns:

uv from 0 to 1

dot

public static float dot(Vertex vertex,
 Vertex axis)
