System and method for constrained manipulations of 3D objects by multitouch inputs

A non-transitory computer readable storage medium having instructions stored thereon that, in response to execution, facilitate performance of operations by a system comprising a processor, the operations comprising:

• changing a viewing parameter in a virtual 3D environment based on a touch motion;
• manipulating a three dimensional object with constraints based on the touch motion, wherein the three dimensional object has been selected via a previous administered first touch gesture;
• and
• snapping the three dimensional object to a second three dimensional object based on an orientation and geometry information of a touch path input.

A system, comprising:

• a memory to store instructions;
• and
• a processor, communicatively coupled to the memory, that executes or facilitates execution of the instructions to perform operations, comprising:
• receiving a selection of a focus object for manipulation based on a first touch gesture;
• selecting a constraint from candidate constraints for the focus object based on an orientation of at least two contact points determined from a second touch gesture;
• determining a transformation mode based on a motion path of the at least two contact points with respect to the constraint;
• and
• applying a constrained transformation to the focus object, wherein the constrained transformation is performed with a magnitude of transformation based on an amount of touch movement along the motion path.
