The U3D Reader provides access to the visualization data stored within a particular U3D file. A file does not need to have a particular extension to be read correctly by HOOPS Exchange however the file extension of U3D files that you can expect to be loaded by HOOPS Exchange are:

  • .U3D

How to Import From U3D

To load a U3D file, use A3DAsmModelFileLoadFromFile(). The A3DParamsLoadData structure is used to customize the loading behavior:

A3DAsmModelFile* pModelFile = 0;

A3DRWParamsLoadData sReadParam;
A3D_INITIALIZE_DATA(A3DRWParamsLoadData, sReadParam);
sReadParam.m_sGeneral.m_bReadSolids = true;

// ... set other A3DRWParamsLoadData fields as necessary

A3DAsmModelFileLoadFromFile("path/to/file.u3d", &sReadParam, &pModelFile);

See Simple Load and Export for more about loading model files.

Miscellaneous

Construction geometries are handled by the reader.

Limitations

The animation stored within a particular file is not exposed to developers. However, if you are providing a U3D file to HOOPS Publish to put into a PDF document then the U3D remains unchanged and the animation remains available and can be exposed in the PDF document.
