Module voxelfuse_examples.blurred_materials.blurred_materials

"""
Multimaterial 3D printing with blurring/dithering.

User inputs a model and the program will apply blurring to requested materials.

- boxes.vox demonstrates two blurred materials and one non-blurred material.
- joint2.1.vox demonstrates a dog bone joint with blurring.
