Improving the performance of hardware shaders |
The MPxHwShaderNode class contains a method supportsBatching() which controls whether or not rendering calls for this material are batched together to minimize rendering state transitions. By implementing this method and returning true, the MPxHwShaderNode’s pre(bind/glBind) and post(unbind/glUnbind) methods will be called once per-frame, rather than once per-shape per-frame. By default, this method returns false to maintain compatibility with previous plug-in implementations. Please refer to the documentation of this method for more details.
