This sample extends VSG by adding a new node type derived from vsGeometryBase. The new node type simply acts as special scene graph node, which is specially designed to work with vrSphere geometries through two new methods called, setSphere and getSphere. Additionally, the node implements its own custom cull records, which allows the texture coordinates of a vrSphere to be scaled via a texture matrix with two other methods called, setTextureScalingFactor and getTextureScalingFactor
