C++ LLViewerVisualParam::getMinWeight方法代码示例

// Avatar parameter and texture definitions can change over time.

// will return true. 
// * If parameters or textures have been ADDED since the wearable was created,
// they are taken to have default values, so we consider the wearable clean
// only if those values are the same as the defaults.
