// DESCRIPTION:
|
|
// a class to handle control points in a 2D view
|
|
// TODO: this one can be placed under an interface, and provided to the editor as service
|
|
//
|
|
// NOTE: the C2DView *m_p2DView is the orthogonal mapping between window and ST space
|
|
// in Drag mode (for rotation) we need an orthonormal XY space
|
|
// we do ST <-> XY transformations using the texture size
|
|
// ( for translation-only moves, orthogonal is enough )
|
|
// FIXME: is there a better way to deal between Window space <-> ST space <-> XY space ?
|
|
//
|
|
// NOTE: ControlPointsManagers are a bit different between brush faces and patches
|
|
// so there's a base virtual class, and we have two versions
|
