建模 — 变形与变换

前置条件：先阅读 unreal-modeling。

库

库	CDO
变形	`/Script/GeometryScriptingCore.Default__GeometryScriptLibrary_MeshDeformFunctions`
变换	`/Script/GeometryScriptingCore.Default__GeometryScriptLibrary_MeshTransformFunctions`

TargetMesh 为 UDynamicMesh* 路径字符串。Debug 省略。需要 FGeometryScriptMeshSelection 的函数，用 MeshOperationLibrary 桥接。

变形函数

函数	关键参数	说明
`ApplyBendWarpToMesh`	`TargetMesh`, `Options`, `BendOrientation`(FTransform), `BendAngle`(float), `BendExtent`(float)	弯曲变形
`ApplyTwistWarpToMesh`	`TargetMesh`, `Options`, `TwistOrientation`, `TwistAngle`, `TwistExtent`	扭曲变形
`ApplyFlareWarpToMesh`	`TargetMesh`, `Options`, `FlareOrientation`, `FlarePercentX`, `FlarePercentY`, `FlareExtent`	膨胀/收缩变形
`ApplyMathWarpToMesh`	`TargetMesh`, `WarpOrientation`, `WarpType`, `Options`	数学函数变形（正弦等）

JSON 中 FTransform：{"Rotation":{"X":0,"Y":0,"Z":0,"W":1},"Translation":{"X":0,"Y":0,"Z":0},"Scale3D":{"X":1,"Y":1,"Z":1}}

JSON 中 FRotator：{"Pitch":0,"Yaw":90,"Roll":0}
