Instance Method

weightForTargetAtIndex:

Returns the weight value for the specified target index.

Declaration

- (CGFloat)weightForTargetAtIndex:(NSUInteger)targetIndex;

Parameters

targetIndex

The index of a geometry in the morpher’s targets array.

Return Value

A number indicating the contribution of the target geometry to the blended surface, generally between 0.0 and 1.0.

Discussion

Target geometries and their weights determine the current form of the surface produced by the morpher. For example, if a morpher has one target whose weight is 0.5, the form of the resulting surface will be halfway between those of the base geometry and the target geometry.
