* Optimize QGraphicsRotation's use of QMatrix4x4Rhys Weatherley2009-10-261-1/+68
| | | | | | | | Previous code was creating a full 3D rotation matrix and then projecting back to 2D. This change combines the two steps into one to avoid calculating matrix components that will be dropped. Reviewed-by: Sarah Smith
* Fix a bug in QGraphicsRotation related to 2D projectionsRhys Weatherley2009-10-221-1/+1
| | | | | | | The projection to 2D needs to be done when the rotation is applied, not after all transformations have been applied. Reviewed-by: trustme

* Re-implement QGraphicsTransform to use QMatrix4x4Rhys Weatherley2009-08-191-32/+109
| | | | | | | | | | QTransform-based transformations create problems when performing X and Y axis rotations because they aren't using true 3D. This change modifies QGraphicsTransform and its sub-classes to use QMatrix4x4 as the standard transformation matrix, with a project() function to project back to 2D when required.

* Set default QGraphicsTransform3D axis to (0, 0, 1)Rhys Weatherley2009-08-101-1/+21
| | | | | | | | | The docs said that the default axis was (0, 0, 1), but the code and unit tests were using (0, 0, 0). Modify the code to match the docs because (0, 0, 0) is not very useful. Also optimize the calculation of sin/cos values for 90, 180, and 270 degrees. Reviewed-by: Aaron Kennedy
* Implement new transformation handling for graphics items.Lars Knoll2009-07-292-0/+164
The idea of having separate rotationX/Y/Z, shearX/Y, etc. methods in QGraphicsItem turned out to be not giving us the flexibility we need and wanted. The new code now implements a different scheme, where we keep simple rotate (around z-axis), scale and transformOriginPoint methods, but remove the other ones. Instead we now have an additional list of QGraphicsTransform object. QGraphicsTransform is an abstract class that inherits QObject. Several specializations are provided and can be used to transform (and through property bindings animate) the item. Reviewed-By: Andreas
