Question

JavaScript => public function AddBlendShapeFrame(shapeName: string, frameWeight: float, deltaVertices: Vector3[], deltaNormals: Vector3[], deltaTangents: Vector3[]): void;
C# => public void AddBlendShapeFrame(string shapeName, float frameWeight, Vector3[] deltaVertices, Vector3[] deltaNormals, Vector3[] deltaTangents);

Parameters 参数

shapeName	Name of the blend shape to add a frame to. 添加到帧的混合图形的名字。
frameWeight	Weight for the frame being added. 帧的权重。
deltaVertices	Delta vertices for the frame being added. 帧的增量顶点。
deltaNormals	Delta normals for the frame being added. 帧的增量法线。
deltaTangents	Delta tangents for the frame being added. 帧的增量切线。

Description 描述

Adds a new blend shape frame.

添加新的混合图形帧。

If blend shape name does not exist then a new blend shape is created. Blend shape frame can only be added to a new or the last blend shape. Usually there will be a single frame for a blend shape, but the range of blending [0-100%] may be split into multiple frames. Weight is assumed to be 100% when a shape only has one frame. Frame must be added in an increasing weight order for blend shapes having multiple frames. deltaVetrices, deltaNormals and deltaTangents arrays must be of size = Mesh.vertexCount. Substract Mesh vertices, normals or tangents to convert from frame full vectors to get deltas. deltaNormals or deltaTangents may be set to null if there is no normals or tangents for a frame.

如果混合图形不存在，那么创建新的混合图形。混合图形帧仅能添加新的或最后的混合图形。通常将单帧用于混合图形，但混合范围[0-100%]可能被拆分成多个帧。当图形仅有一帧时，权重认定为100%。混合图形有多帧时，添加帧必须增加权重顺序。deltaVetrices、deltaNormals 和 deltaTangents数组的大小=Mesh.vertexCount。减少网格顶点、法线和切线，从帧所有向量到获取增量来转换。如果该帧没有法线和切线，deltaNormals或deltaTangents可设置为null。
