Detailed Description

Dialog + mechanism for graphical transformation of entities.

Mouse driven rotation and translation of selected entities at screen.

Member Function Documentation

addEntity()

bool ccGraphicalTransformationTool::addEntity

(

ccHObject *

anObject

)

Adds an entity to the 'selected' entities set.

Only the 'selected' entities are moved.

Returns

success, if the entity is eligible for graphical transformation

Member Data Documentation

m_rotationCenter

CCVector3d ccGraphicalTransformationTool::m_rotationCenter

protected

Rotation center.

The rotation center is actually the center of gravity of the selected 'entities'
