Using Bitmap Patterns

Similar to typographic half-tone patterns which approximate high-resolution vector graphics into finite printable graphics - 2D bitmap patterns can be used to create 3D mesoscopic half-tone patterns.  

Mappings

When using bitmap images as a mesoscopic pattern, you can choose how you want that bitmap mapped throughout the volume. Current mappings include extruding along the XY, YZ, and XY axes as well as multiplicative and additive blending modes. As evidenced by the images on the right, the way in which an image is mapped to a model can have a profound visual impact.

Using Voxel Patterns 

Three dimensional voxel patterns can also be used as a half-tone pattern.  The image on the right shows a 3D Gyroid voxel pattern being propagated throughout a larger macroscopic field condition.
