function LoadNode(const URL: String): TX3DRootNode; |
|
Load model, just like X3DLoad.LoadNode but with a cache. URL must be absolute (not relative). Note that this should not be used if you plan to modify the model graph (for example by VRML/X3D events). In such case, the cache should not be used, as it would make all the model instances shared. For example, if you inline the same model multiple times, you could not modify one instance independent from another. | |

function IsCached(const URL: String): Boolean; |
|
Is the given URL cached. | |
