OBB::Scale
Syntax
void OBB::Scale(const float3 ¢erPoint, float scaleFactor); [4 lines of code]Applies a uniform scale to this OBB.
This function scales this OBB structure in-place, using the given center point as the origin for the scaling operation.
Parameters
const float3 ¢erPointSpecifies the center of the scaling operation, in global (world) space. floatscaleFactorThe uniform scale factor to apply to each global (world) space axis.
Performance
1.03μsecs/call ≈ 970.48k calls/second ≈ 16.17k calls/frame (@ 60fps).
This function does not perform dynamic memory allocation.

Syntax
void OBB::Scale(const float3 ¢erPoint, const float3 &scaleFactor); [6 lines of code]Applies a non-uniform scale to the local axes of this OBB.
This function scales this OBB structure in-place, using the given global space center point as the origin for the scaling operation.
Parameters
const float3 ¢erPointSpecifies the center of the scaling operation, in global (world) space. const float3 &scaleFactorThe non-uniform scale factors to apply to each local axis of this OBB.
Performance
2.049μsecs/call ≈ 488.16k calls/second ≈ 8.14k calls/frame (@ 60fps).
This function does not perform dynamic memory allocation.

Work in progress:
Bug: in void OBB::Scale(const float3 ¢erPoint, const float3 &scaleFactor):
This scales in global axes, not local axes.
