Constructor & Destructor Documentation

csOBBFrozen::csOBBFrozen (  )  [inline]

Create an empty csOBBFrozen which is not initialized.

Definition at line 142 of file obb.h.

csOBBFrozen::csOBBFrozen ( const csOBB obb  )  [inline]

Create a frozen OBB from a normal OBB.

Definition at line 149 of file obb.h.

csOBBFrozen::csOBBFrozen ( const csOBB obb,
const csReversibleTransform trans 
) [inline]

Create a frozen OBB from a normal OBB.

The given transform is applied to the vertices AFTER the matrix of the obb is applied (using Other2This).
