Embodiment Construction

[0012] An automatic conversion method between a Maya instance and a USD point instance, comprising the following steps:

[0013] USD to Maya: Import USD file and analyze the USD file, and convert the corresponding USD geometric point instance into the corresponding instance node in the Maya file, and set the corresponding parameter value;

[0014] Maya to USD: When exporting an instance in Maya, write out the USD geometric point instance, and set the data of the instance to the corresponding USD geometric point instance node;

[0015] Specifically, import the USD file and analyze the USD file, convert the corresponding USD GeomPointInstancer (GeomPointInstancer) into the corresponding instance node in the Maya file, and set the corresponding parameter value. Write out the USD GeomPointInstancer (GeomPointInstancer) when exporting the instance (instance) in Maya, and set the data of the instance (instance) to the corresponding USD GeomPointInstancer (GeomPointInstancer) node; ...

Abstract

The present invention provides an automatic conversion method between a Maya instance and a USD point instance, comprising the following steps: converting USD to Maya: importing a USD file and parsing the USD file, and converting the corresponding USD geometric point instance into a corresponding Maya file Example node, and set the corresponding parameter value, the set parameter value is connected to the example input point attribute in the USD geometric point instance data in the Maya file; Maya to USD: when exporting the instance in Maya, write the USD geometric point instance, And set the data of the instance to the corresponding USD geometric point instance node. The present invention converts instance elements between Maya and USD libraries.

Description

technical field [0001] The invention belongs to the technical field of animation production, and in particular relates to an automatic conversion method between a Maya instance and a USD point instance. Background technique [0002] USD (Universal Scene Description) is an open source file format and tool proposed by Pixar. It provides a series of tools to convert scene elements in 3D software such as Maya into corresponding USD elements. Animal Logic USD is a USD-based plug-in, and animation production can develop corresponding tools based on the Animal Logic USD plug-in, but there is no interaction between the USD geometry point instance (GeomPointInstancer) and the Maya instance (instance) in Animal Logic USD automatic conversion, which has a difficult impact on animation production. Contents of the invention [0003] The purpose of the present invention is to provide a kind of automatic conversion method of Maya example and USD point example, realize the conversion ex...
