Cuboids

Cuboid example script:

• Geometry: geometry.ConvexPolyhedron: outline_width = 0.015

  • material: roughness = 0.1, specular = 1, metal = 0, spec_trans = 0

  • outline_material: roughness = 0.1, metal = 1, spec_trans = 0, color = (0.95,0.93,0.88)

  • position, orientation: output of a HOOMD simulation

• Lighting: light.lightbox

• Rendered with: tracer.Path: samples = 256, light_samples = 16
