Example: Triangular Mesh Geometry

Warning

Note that in order for meshes to work properly in RustBCA, the following must be true:

• meshes must consist of only triangles
• meshes must be "watertight" (e.g., check with trimesh: mesh.is_watertight must return True)
• all surface normals must point outwards (fix with trimesh: mesh.fix_normals())

Triangular Meshes for Homogeneous Composition, Complex Objects

Using parry3d, RustBCA can use full 3D triangular meshes. These are currently limited to homogeneous, single-mesh targets, but compound objects and inhomogeneity are planned features for triangular meshes.

To use this feature, run one of the examples below:

• cargo run --release --features parry3d TRIMESH examples/tungsten_twist_trimesh.toml
• cargo run --release --features parry3d TRIMESH examples/tungsten_tiles.toml

These examples can be plotted using rustbca.py (requires toml, shapely, mayavi, numpy, matplotlib):

from scripts.rustbca import *
do_trajectory_plot_3d('tungsten_twist_', input_file='examples/tungsten_twist_trimesh.toml')
