Displacement Mapping

Standard and Professional Only

Displacement Mapping uses texture maps to represent the unevenness of an object. Unlike bump mapping or a normal map, this function does not use pseudo mode to represent unevenness by changing the slant of the object surface (normal line direction). It actually deforms the object. For this reason, unevenness is reproduced using shadow shapes. Moreover, this function can save a displaced version as an actual object. Displacement Mapping is only available in Shade Standard and Professional.

Setting the Displacement Map

1 Select the object for which the displacement map is to be set.

2 Set the pattern in the Mapping group of the Surface window and then set the Displacement in the Attribute popup menu (1). According to the object fineness or mapping pattern fineness, set the fineness of the displacement from the Displace div. popup menu (2). Here, Fine has been set.

3 Once you perform rendering, the density of the pattern is represented as being uneven.

Conversion to an Actual Object

1 Select the object for which the displacement map is set and then from Tool Parameters, click Convert to Polygon Mesh.

2 From the displayed dialog, check the Bake Displacement Mapping checkbox.

3 A confirmation dialog is displayed. Click Yes.

4 Conversion is performed to convert the displacement map to an actual object.

TIP

In comparison with the bump mapping and normal mapping, a displacement map consumes much more memory during rendering, thus resulting in a long ren-dering time.
