Model sharing and rendering method based on Alembic, and an electronic terminal

Abstract

The invention discloses a model sharing and rendering method based on Alembic and an electronic terminal. The method comprises the following steps: selecting a locally stored model file and importingthe model file into an animation component; the animation component obtains the original model and the replication model of the original model according to the model file. In the animation component,copy model is selected as the deformation basis, and the original model and copy model are fused and deformed to obtain the target model. whether to cache the target model is judged; after judging thecache target model, the abc cache file of the target model and the rendering file matched with the abc cache file are exported through the animation component. The rendering file at least includes the material information and texture mapping information of the target model. The invention can avoid that the original model cannot be matched with the geometric result of the cache because of the subsequent modification of the original model, on the other hand, the original model can be quickly restored through the combination of the derived material information and texture mapping information andthe abc cache file, and the operation flow is simplified.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to an Alembic-based model sharing and rendering method and an electronic terminal. Background technique [0002] In the production process of 3D animation, in order to improve rendering efficiency, it is usually necessary to make relevant character props in the lens as a geometric buffer. [0003] Among them, the Alembic cache is the currently widely used file format; the Alembic file format (hereinafter referred to as the abc cache file) is an open computer image exchange framework; it can distill complex scenes with animation into a set of non-processes and applications Program-independent baking geometry results. [0004] The abc cache file includes the displacement, vertex, UV, and visibility information of the above-mentioned cached geometric results; it does not include information such as the material and texture maps of the cached geometric results. [0005] After using May...

Problems solved by technology

[0006] The embodiment of the present invention at least discloses an Alembic-based model sharing method, which can solve the problem that the abc cache file in the prior art can only cache the geometric results of the model, resulting in the need to import the geometric results of the abc cache file and rebuild the geometric structure before subsequent rendering Technical issues of complex operations such as materials and texture maps
