Struct dmc::duals::DualGrid [−][src]
Type that defines a grid made from the dual edges of an octree.
Visual Example
Here’s an example simplified in a quadtree.
Possible Implementation
Here’s a possible implementation simplified in a quadtree, without comments or nice code: It’s meant mostly as a visual guide of what the dual grid looks like.
Fields
volumes: Vec<[MortonKey; 8]>
The cells or volumes that make up this dual grid.
Each one is composed by, at most, 8 different dual vertices.
They are always presented in the same order: The same one as defined in
[dmc::octree::OctreeIndex
].
Notes
Some cells will have shared vertices, however, their topology will be the same one as a cube, so the Marching Cubes algorithm will work over them.
Implementations
impl DualGrid
[src]
pub fn from_octree<T: Copy + Send + Sync>(octree: &HashedOctree<T>) -> Self
[src]
Constructs a dual grid from a given octree.
You won’t require to create an object of this type yourself unless you plan on processing
the duals. If you want to generate a mesh from an octree, use
crate::dmc::mesh_from_octree
.
Example
use dmc::octree::*; use dmc::duals::*; let mut octree = HashedOctree::new(1); octree.subdivide(MortonKey::root()).for_each(drop); assert!(octree.is_subdivided(MortonKey::root())); assert_eq!( octree.leaves(MortonKey::root()), vec![ MortonKey(0b1111), MortonKey(0b1110), MortonKey(0b1101), MortonKey(0b1100), MortonKey(0b1011), MortonKey(0b1010), MortonKey(0b1001), MortonKey(0b1000), ] ); let duals = DualGrid::from_octree(&octree); assert_eq!( duals.volumes, vec![[ MortonKey(0b1111), MortonKey(0b1110), MortonKey(0b1101), MortonKey(0b1100), MortonKey(0b1011), MortonKey(0b1010), MortonKey(0b1001), MortonKey(0b1000), ]] );
