Interactions in 3D
Welcome to the HODLR3D Documentation pages! Here you can quickly view various 3D interactions that help you in understanding 3D.
Hierarchical Sub-division of the domain in 3D
Consider a box (a cube) in 3D which corresponds to root node in the hierarchical tree (Level 0)
Subdivision of the domain hierarchically results in 8 smaller cubes (each corresponding to 8 children nodes of the root node in the Hierarchical tree). (Level 1 Subdivision)
Further subdivision (Level 2) results in 64 cubes as shown below:
Different types of interactions in 3D
Based on how the boxes share boundary, they can be classified as following types:
- Vertex sharing intractions
- Edge sharing intractions
- Face sharing intractions
- Far field intractions
Vertex sharing intractions
Consider a box (at level 2) in 3D then it the boxes that share atmost an vertex are named VERTEX sharing boxes
Edge sharing intractions
For a box highlighted in black, the edge sharing boxes are colored in green.
Face sharing intractions
Further the face sharing boxes are shown below:
Far field intractions
The boxes that do not share a boundary is said to have far field intractions.
