Displacement Bound
Specifies the displacement bound for the attached objects, which is the amount by which the bounding box of each object should be increased to include the displaced surfaces. Failure to provide the renderer with a decent value will result in shading artifacts (when the value is too small) or inefficiency (when the value is too large). When the displacement bound is too small, 3Delight issues an error message stating by how much the value is too small; it is recommended to use this information to assign a reasonable bound. The default value is ‘0.0’, which is fine only if the surfaces are not displaced.
Bound Space
This attribute defines in which space the Displacement Bound parameter is defined. The default space is ‘shader’.
