Member Function Documentation
| float** ot::MatrixTransformation::getMatrix | ( | ) | [inline] |
returns the affine part of the Transformation
- Returns:
- float pointer to 3x4 floats
Definition at line 113 of file MatrixTransformation.h.
| void ot::MatrixTransformation::setMatrix | ( | float * | data[4] | ) | [inline] |
sets the scale of the transformation.
It is only executed, if the transformation is of type to change the position of any events. It copies the passed float array into an internal structure.
- Parameters:
-
data a 3x4 float array containing the scale

transforms a event.
Overrides the Transformation implementation to implement a different one.
Implements ot::Transformation.
