/* workflow:
|
||
|
|
|
||
|
|
1) create a new scene wrapper
|
||
|
|
2) populate an array of of meshHelpers for each mesh in the original scene
|
||
|
|
3) (eventually) create an animator instance
|
||
|
|
4) scale the asset (needed?)
|
||
|
|
5) create the asset data (GL resources, textures etc)
|
||
|
|
5a) for each mesh create a material instance
|
||
|
|
5b) create a static vertex buffer
|
||
|
|
5c) create index buffer
|
||
|
|
5d) populate the index buffer
|
||
|
|
5e) (eventually) gather weights
