The RenderScript vertex program, also known as a vertex shader, describes a stage in + * the graphics pipeline responsible for manipulating geometric data in a user-defined way. + * The object is constructed by providing the RenderScript system with the following data:

+ * + * + *

Once the program is created, you bind it to the graphics context, RenderScriptGL, and it will be used for + * all subsequent draw calls until you bind a new program. If the program has constant inputs, + * the user needs to bind an allocation containing those inputs. The allocation's type must match + * the one provided during creation. The RenderScript library then does all the necessary plumbing + * to send those constants to the graphics hardware. Varying inputs to the shader, such as position, normal, + * and texture coordinates are matched by name between the input Element and the Mesh object being drawn. + * The signatures don't have to be exact or in any strict order. As long as the input name in the shader + * matches a channel name and size available on the mesh, the runtime takes care of connecting the + * two. Unlike OpenGL, there is no need to link the vertex and fragment programs.
