Motion Transfer Lip Sync



Uses audio analyzis of user speech to apply lip synchronization without the use of face tracking hardware. The result of the lip synchronization provides weights for visemes. These weights are used as vertex position set weights (blend shapes or morphs in other applications) to perform mouth animation. Each viseme is assigned a vertex position set.</description>

[DEMoCap]

The DEMoCap Application allows to do Motion Capture using VR equipment. DEMoCap is build using the Drag[en]gine game engine. The resulting captured animations are usable directly in the Drag[en]gine game engine or can be imported into Blender for editing. Using Blender the captured animations can be used for all other purposes Blender can be used for.</description>
