RegionEmbeddingDimension

gives the dimension of the space in which the region reg is embedded.

Details

• RegionEmbeddingDimension is also known as space dimension.
• The embedding dimension gives the dimension of the ambient space in which reg is embedded.

Properties & Relations(8)

RegionEmbeddingDimension is the dimension of the space in which a region is embedded:

RegionDimension is the dimension of the point set that the region represents:

RegionEmbeddingDimension is always greater than or equal to RegionDimension:

RegionEmbeddingDimension is the number of variables needed for a point in the region:

Since the embedding dimension is 3, three variables are needed:

Since the embedding dimension is 3, the point p is taken to have length 3:

RegionEmbeddingDimension for MeshRegion corresponds to the length of points:

Similarly for BoundaryMeshRegion:

For an ImplicitRegion, RegionEmbeddingDimension is the number of variables:

For a ParametricRegion, RegionEmbeddingDimension is the number of equations:

Boolean operations are defined for regions of the same RegionEmbeddingDimension:

With the same embedding dimension, the operation is well defined:

Boolean operations do not change the RegionEmbeddingDimension:

Various Boolean operations all have the same embedding dimension:

The RegionEmbeddingDimension of a RegionProduct is the sum of the input dimensions:

The resulting embedding dimension is the sum:
