Interface OBJ_RectBounds

A RectBounds is a rectangle bounds around a point in a plane.

It is defined by:

• a position in plane around which rectangle is formed
• topDirection/rightDirection vectors that orient the rectangle
• left/right magnitudes that define the width of the rectangle
• bottom/top magnitudes that define the height of the rectangle

A rectangle can be defined in one of several ways:

• position, plane normal, one direction vecvtor (top or right)
• position, top and right direction vectors

By default the rectangle will be in the XY plane (+z normal) with a rightDirection vector along the +x axis.
