Digital Media Concepts/Shrinkwrapping
Shrinkwrapping is a technique used in 3D modelling to conform mesh onto the surface of an object.
Functionality[edit | edit source]
Shrinkwrapping functions by moving the vertices of a 3D object to positions that correspond with the surface of another object.[1] The method of identifying surface points varies, but tends to align with the strategies covered below.
Projection Methods[edit | edit source]
- The vertices of the shrinkwrap object are projected along an axis until they touch the surface of the target object.[1] Vertices that are projected onto an angled portion of the target object will not be accurately located, resulting in a "crumpled" appearance.[2]
- The vertices of the shrinkwrap object are unfolded and mapped to the UV surfaces of the target object.[3] This application of shrinkwrapping reads the target object as a flat surface, accurately representing the dimensions of the shrinkwrap object on the curved surface of the target object.
- The vertices of the shrinkwrap object are snapped to the closest vertices on the target object.[1]
Utilization in Rigging[edit | edit source]
Shrinkwrapping is used in the animation workflow as a method of conforming flexible mesh to a guide surface.[4]
Skin Sliding[edit | edit source]
Shrinkwrapping can be used to project a 'skin' mesh onto a similarly proportioned body mesh.[4]
When the vertices of the skin are moved, they will emulate real skin by sliding over the surface of the body mesh.
Attaching Accessories[edit | edit source]
Shrinkwrapping can be used to attach a piece of mesh to the surface of an object.[4]
This application of shrinkwrapping can be used to apply flexible, profile-conforming decorations to an object.
Utilization in Mesh Creation[edit | edit source]
Shrinkwrapping is used in the modelling workflow as a method of creating simplified topology.[4]
Retopology[edit | edit source]
Shrinkwrapping can be used to conform a subdivided surface to the profile of a high-resolution mesh.[5]
This use of shrinkwrapping creates a simplified replica of the source mesh, aiding in the process of retopology.
Capturing Detail[edit | edit source]
Shrinkwrapping can be used to emboss the details of a high-resolution object onto a flat piece of mesh.[4]
