$image\GraySourceImage.gif$

Now suppose you call the function. The following settings apply to all of the following figures:

Parameter	Value
uOffsetX	0

uBricksHeight	20

If you were to use the following additional settings:

Parameter	Value

uMortarRoughnessEvenness	0
uBricksRoughness	0
uBricksRoughnessEvenness	0
uFlags	BRICKS_SMOOTHEDOUT

The following figure results:

Note how smooth the surface of both the mortar and the bricks is. In the following figure, the only change from the previous settings is the value of uBricksRoughness, which is set to 196:
