FindRegionTransform

FindRegionTransform[reg1,reg2]

gives the transformation function that maps the region reg1 to the region reg2.

Details and Options

  • FindRegionTransform is typically used to get transformations between regions that preserve geometric properties such as lines and parallelism.
  • FindRegionTransform[reg1,reg2] gives the affine transformation that maps reg1 to reg2.
  • The following option can be given:
  • WorkingPrecisionAutomaticthe precision to use in internal computations
