Return Values

Returns pOut.

Description

Creates a texture coordinate conversion matrix for Softimage.

[S] [R] [T]

[S] = |scaleS 0 0 0|
| 0 scaleT 0 0|
| 0 0 1 0|
| 0 0 0 1|
[R] の回転方向は Maya および Max とは逆方向が正
[R] = | rotateCos rotateSin 0 0|
|-rotateSin rotateCos 0 0|
| 0 0 1 0|
| 0 0 0 1|
[T] = t(-translateS, -translateT)
