This sample demonstrates using the NV_path_rendering OpenGL extension to draw text arranged like spokes in a wheel, with a slight 3D projection applied to the rendering.
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.
