VertexSlider Class Reference

This is an abstract base class that retains some slider value, which is a linear value that typically ranges from 0.0 to 1.0, and is used to control the animation of morphs (blend shapes). More...

 Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. This should normally not need to be called by user code; it should be called internally when the object has been changed in a way that legitimately requires its retransmission to any connected clients.

Detailed Description

This is an abstract base class that retains some slider value, which is a linear value that typically ranges from 0.0 to 1.0, and is used to control the animation of morphs (blend shapes).

It is similar to VertexTransform, which keeps a full 4x4 transform matrix, but the VertexSlider only keeps a single float value.
