Represents a linear 2D transformation between brush UV space and a target XY space (typically this is a Terrain-local object space.)
The BrushTransform represents a rectangular brush, with scale, rotation, and skew.
The brush is assumed to lie in the [0,1] range in brush UV space.
The transform and its inverse are represented as follows:
xy = u * BrushTransform.brushU + v * BrushTransform.brushV + BrushTransform.brushOrigin
uv = x * BrushTransform.targetX + y * BrushTransform.targetY + BrushTransform.targetOrigin
| brushOrigin | (Read Only) Brush UV origin, in XY space. |
| brushU | (Read Only) Brush U vector, in XY space. |
| brushV | (Read Only) Brush V vector, in XY space. |
| targetOrigin | (Read Only) Target XY origin, in Brush UV space. |
| targetX | (Read Only) Target X vector, in Brush UV space. |
| targetY | (Read Only) Target Y vector, in Brush UV space. |
| BrushTransform | Creates a BrushTransform. |
| FromBrushUV | Applies the transform to convert a Brush UV coordinate to the target XY space. |
| GetBrushXYBounds | Get the axis-aligned bounding rectangle of the brush, in target XY space. |
| ToBrushUV | Applies the transform to convert a target XY coordinate to Brush UV space. |
| FromRect | Creates an axis-aligned BrushTransform from a rectangle. |
