Point Displacer deforms geometric objects using material mapping objects.

The displacement effect is defined by one or several material mapping objects, which are sub objects for the displacer.

A displaced mesh consists of a mesh and a displacer object

When using multiple materials for displacement, the selected materials are responsible for combining the computed channel values. A working combination could be:

  material1                              material2  
     surface properties                     surface properties
        color=*noise(map coords)               color=*curve(map coords)

The shaders below will not combine well (only the latter material mapping counts):

  material1                              material2  
     surface properties                     surface properties
        color=noise(map coords)                color=curve(map coords)

Point Displacer has the following controls:

Channel: Selects the material channel, which defines the displacement.

Space: Orientation for moving the target points.

Absolute - The world space defines displacement direction. If the 1D option is set (or the selected channel is one dimensional), displacement happens along the Z direction of the world space. Otherwise the first sub channel component defines X displacement, second sub channel Y displacement etc.
Object - The object space of the point displacer itself (not of the target mesh!) defines the orientation for displacement. For example, if 1D option is set, the target mesh is displaced along the blue Z axis of the displacer space.
UVW Space - The surface orientation of the original non-displaced mesh defines the displacement direction. In 1D case, the target surface is displaced perpendicularly i.e. along its normal.

1D: - If set, the target mesh is displaced only in Z axis/Surface normal direction. If the selected channel is 3 dimensional, the sub channel average defines applied 1D displacement values. 1D displacement is usually the most intuitive and easiest deformation available via this constructor.
