RegionProduct
RegionProduct[reg1,reg2]
represents the Cartesian product of the regions reg1 and reg2.
RegionProduct[reg1,reg2,…]
represents the Cartesian product of the regions reg1, reg2, ….
Details
- RegionProduct is also known as outer product region.
- RegionProduct[reg1,reg2] represents the region .
- The embedding dimension of the product region is the sum of embedding dimensions, and the geometric dimension is the sum of geometric dimensions.
