Autodesk.Viewing.FileLoader
new FileLoader(viewer)
Base class for file loaders.
It is highly recommended that file loaders use worker threads to perform the actual loading in order to keep the UI thread free. Once loading is complete, the loader should call viewer.impl.onLoadComplete(). During loading, the loader can use viewer.impl.signalProgress(int) to indicate how far along the process is.
To add geometry to the viewer, viewer.impl.addMeshInstance(geometry, meshId, materialId, matrix) should be used. Geometry must be THREE.BufferGeometry, meshId is a number, materialId is a string, and matrix is the THREE.Matrix4 transformation matrix to be applied to the geometry.
Remember to add draw calls to the BufferGeometry if the geometry has more than 65535 faces.
Parameters
