This sample demonstrates how to render skinned meshes using both one or two bones in a vertex shader. Skinning allows organic shapes (such as humans) to deform nicely around joints as they bend. Without skinning, joints have a rigid appearance that is more similar to a mechanical joint like you would see in a robot.
The OpenGL samples all share a common app framework and certain user interface elements, centered around the "Tweakbar" panel on the left side of the screen, which lets you interactively control certain variables in each sample.
To show and hide the Tweakbar, simply click or touch the triangular button positioned in the top-left of the view.
Other controls are listed below:
Skinning is a good way to improve the quality of animated, organic meshes at a reasonable vertex shader cost.
