## Detailed Description

Version of the csOBB with frozen corners (for optimization purposes).

Definition at line 117 of file obb.h.

## 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).
