base class for immediate rendering objects.
++ This experimental class provides a fast code path for rendering meshes with frequently updated + geometry data. When the renderer encounters an instance of [name], it only takes care about + the most primitive rendering operations (e.g. binding vertex attributes, determining correct shader + program or perfoming the actual draw call). Features like view frustum culling, wireframe rendering + or using multiple materials are not supported. Besides [name] can only be used to render triangles. +
+ ++ [name] does not work with instances of [page:BufferGeometry] or [page:Geometry]. The + raw geometry data have to be maintained as properties of the [name]. +
+ ++ Using [name] makes only sense if you are updating your geometry data per frame. You can then + benefit of a faster code path compared to the default mesh redering logic. +
