Properties & Relations (8)Properties of the function, and connections to other functions
RegionEmbeddingDimension is the dimension of the space in which a region is embedded:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-keq3fv

https://wolfram.com/xid/01lsa6i4qy01q2v8i-mckpz

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

https://wolfram.com/xid/01lsa6i4qy01q2v8i-eieytl

RegionEmbeddingDimension is always greater than or equal to RegionDimension:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-ievhdr

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

https://wolfram.com/xid/01lsa6i4qy01q2v8i-dbljxt

https://wolfram.com/xid/01lsa6i4qy01q2v8i-kdoxzk

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

https://wolfram.com/xid/01lsa6i4qy01q2v8i-bojrr5

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

https://wolfram.com/xid/01lsa6i4qy01q2v8i-edadcf

RegionEmbeddingDimension for MeshRegion corresponds to the length of points:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-hfoqwq


https://wolfram.com/xid/01lsa6i4qy01q2v8i-gmalef

Similarly for BoundaryMeshRegion:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-df868p


https://wolfram.com/xid/01lsa6i4qy01q2v8i-o47whs

For an ImplicitRegion, RegionEmbeddingDimension is the number of variables:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-c7nr7r


https://wolfram.com/xid/01lsa6i4qy01q2v8i-bsxfnv

For a ParametricRegion, RegionEmbeddingDimension is the number of equations:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-b22zdr


https://wolfram.com/xid/01lsa6i4qy01q2v8i-bi58y8

Boolean operations are defined for regions of the same RegionEmbeddingDimension:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-isvwwt



https://wolfram.com/xid/01lsa6i4qy01q2v8i-famngs

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

https://wolfram.com/xid/01lsa6i4qy01q2v8i-74ltb


https://wolfram.com/xid/01lsa6i4qy01q2v8i-jczshf

Boolean operations do not change the RegionEmbeddingDimension:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-bouzlo

https://wolfram.com/xid/01lsa6i4qy01q2v8i-b21j11

Various Boolean operations all have the same embedding dimension:

https://wolfram.com/xid/01lsa6i4qy01q2v8i-dv5oms

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

https://wolfram.com/xid/01lsa6i4qy01q2v8i-pn6prk

https://wolfram.com/xid/01lsa6i4qy01q2v8i-dt0hy1

The resulting embedding dimension is the sum:
