Embodiment one
The present embodiment discloses a kind of model sharing method based on Alembic.Method one side energy through this embodiment
Enough avoid the geometric consequence for making caching because of subsequent modification archetype that from can not matching with the archetype before modification, on the other hand
Archetype can be quickly restored by the combination of derived material information and texture mapping information and abc cache file, simplified
Operating process.
In order to realize above content, Fig. 1 is please referred to；The step of the present embodiment method, implements as follows.
Step110, selection are stored in the model file of local folders.
Step120, model file is imported in Maya, obtains the archetype for having animation.
Step200, in the reconstructed model of Maya replicating original model.
Step310, the shape blending anamorphoser Blend Shape for selecting Maya, it is basic using reconstructed model as deformation, it is right
Archetype and reconstructed model carry out fusion deformation, obtain object module.
The object module of this implementation using reconstructed model as the basis of fusion deformation, can be such that reconstructed model protects always always
Hold all initial characteristics of archetype.So before rendering, even if archetype is modified, it can also guarantee object module
Initial characteristics with archetype.
Step320, after modifying archetype according to user demand, judge whether the abc caching text for exporting object module
Part.The foundation of the abc cache file of the present embodiment export object module is that the model of rendering during determining follow-up rendering is
Archetype before modification.
Step330, judgement export object module abc cache file after delete target model deformation history, even if
Object module and the archetype of importing are consistent.Alternatively, being deleted after the abc cache file that judgement does not export object module
Object module.
Step400, export abc cache file and with the matched rendering file of abc cache file, render file include at least
With the matched material information of abc cache file and texture mapping information.
Step500, abc cache file and rendering file are imported in the houdiini for being rendered；It is also possible to
3Dmax or maya etc. other.
Step610, due to abc cache file save be bake after geometric consequence；So in houdiini according to abc
The geometric consequence of cache file acquisition object module.
Step620, in houdiini according to rendering file acquisition and the matched material information of geometric consequence and texture mapping
