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. |
