问题
We are using Skinned meshes (with bones to deform it), and are looking to implement face accurate mouse picking for the faces on the SkinnedMesh. ( so we can pick a face and get it's coordinates ) .
The mesh skin deformation is done on the GPU - which presents an issue reading transformed vertices back out - and for accurate mouse picking.
has anyone got any pointers to implement this functionality ? or is there a solution for this somewhere ( I have been looking for a while ) ?
We are using Three.js r67. - but happy to migrate to any version if there is a solution for this.
Thank you for your help / time.
