Model dice
Create a 3D model of a die (plural dice). Make the dots distinguishable from the surface (e.g., by modeling impressions with white or black paint). The die should have rounded edges or be stylized, a simple box will not suffice.
BRL-CAD provides several ways to model 3D geometry including a graphical tool named mged, another named archer, and various ways to create geometry using scripts. Create your model using BRL-CAD, not via import. Create one top-level combination to group everything together. Intersection of rpp with a sph may be helpful...
Start with some MGED tutorials if you haven't yet, which are a separate task! You can learn the basics of 3D modeling in just an hour or two.
SUBMIT a PNG image, your geometry in BRL-CAD ".g" file format, and a text explaining how&why you made your model the way that you did.
