Morphing Tool: How it can be used to modify the shape of the heart
-
This post illustrates the "Morphing Tool" and how it can be used to modify the shape of the heart, without creating gaps or overlaps.
First, a deformation field is "created" in the UI. Once the user is happy, the deformation is saved to file so that it can be applied to the whole body, or edited again later.
When we apply the deformation to the entire body, interfaces between tissues move in exactly the same way, so not gaps or overlaps can occur.
