VertexDataProvider Class Reference
#include <renderer.h>
Class Description
This interface can be used to provide additional vertex data for the rendering.
When an object with this type is added as a child to a Mesh object in the scene graph, the renderer uses that object to obtain additional vertex data for the rendering (like vertex color, bone indices and weights). This interface is important when you want to use your own custom shader for rendering, which needs more data than the usual vertex data (position, normal, etc.).

This function must return an array of vertex indices whose data has been changed since the last call to this function.
There are two ways to update the buffers in the renderer object:
- When most or all of the vertices need to update, the VertexDataProvider object can instruct the renderer to do a global update on all the vertices by calling ContentChanged() on itself. This way the renderer will know about the change, and refresh every vertex buffer which contains data from this object.
- If only subset of the vertices are changed, the VertexDataProvider can collect the indices of the changed vertices to an array, and pass that array to the renderer when this function is called. The renderer will update the specified vertices, and clear the array. The VertexDataProvider can continue storing dirty vertex indices into the array after the call.
