3D Nodes Example

3D Image Nodes treat their inputs as height maps from which they internally construct a three-dimensional surface.  This surface is then used for a variety of 3D operations, such as illuminating it with a light source, or casting shadows.

 

In the example at the left a Point Light node is illuminating a height map to make it appear three-dimensional.

 

 

Node

Description

Caustics

Calculates where light concentrates after it passes through a refractive surface.

Full Light

Shades a three-dimensional surface using full environmental lighting.

Point Light

Shades a surface as if it were illuminated by a point light.

Reflect

Reflects a base image against a perfectly reflective three-dimensional surface.

Refract

Refracts a base image through a refractive surface.

Shadow

Calculates the shadows that an irregular surface would cast on itself if it were illuminated by a point light.

Stereogram

Creates a stereogram illusion where a 3D surface is encoded within a repeating pattern.

Transmit

Projects an image through a refractive surface.
