Member Function Documentation

TransformationData GoGoCursorModel::generateCursorTransformation	(	TransformationData	userTransformation,
		User *	user
	)			`[virtual]`

The method calculates the transformation of the cursor in world coordinates. If the distance between the user and the user's hand exceeds the distance threshold, the non-linear mapping is performed. resultVec = resultVec + distVec/dist * (dist-distanceThreshold)^2 * k resultVec...result vector distVec...distance vector betwenn user and user's hand dist...length of the distance vector

Parameters:

	userTransformation	transformation of the User
	user	the user to calculate the cursor-transformation for

Returns:: transformation of the user's cursor

Implements CursorTransformationModel.

std::string GoGoCursorModel::getName ( ) [virtual]

The method returns the name of the CursorTransformationModel, which is also the name of the class: "GoGoCursorModel". This name has to be equal with the name which is checked in the CursorTransformationModelFactory.
