Clamping Functions

Geometry Functions

• atanP - function returns only positive values between [0, 2π]
• calculateDirection -Calculates the direction between two points relative to the vector pointing in the trailing direction
• project - Projects the point p onto the line segment defined by the points L1 and L2
• calculateParameter - Projects the point p onto the vector defined by the points L1 and L2, uses the parametric form of the line segment from L1 to L2 to constrain the projected point to be on the line segment
• distance - gets the distance between two points
