Member Function Documentation

obb3 obb3.createSpoke (  vec3  centerTop, mat3  axis, vec3  size )  [static]

Create a spoke oriented bounding box. Parameters: centerTop  The center of the top of the bounding box. axis  The orientation axis. size  The dimensions of the bounding box. Returns: An oriented bounding box describing these parameters.

bit obb3.overlaps (  obb3  other  )

Return whether the bounding boxes overlap one another. This function was stolen from ODE. Parameters: other  The other oriented bounding box to test against. Returns: Whether the bounding boxes overlap one another.

void obb3.toPlanes (  plane3  planes[]  )

Convert the oriented bounding box into six planes. Parameters: planes  The planes to store the box into. This must have a length of six.
