List of toBarycentric() Examples

Examples of toBarycentric()

toxi.geom.Triangle2D.toBarycentric()
Produces the barycentric coordinates of the given point within this triangle. These coordinates can then be used to re-project the point into a different triangle using its {@link #fromBarycentric(ReadonlyVec3D)}method. @param p point in world space @return barycentric coords as {@link Vec3D}
