STL and PLY files can be generated by most 3D packages from any form of triangle-mesh dataset. STL files are the most reliable interchange format; PLY files generated by some software might not be compatible with SPIERSview, but PLY files can incorporate surface colour information (e.g. from laser scanners). VAXML files can be either hand-generated (see examples and specifications below), or generated by SPIERSview. VAXML exporters and importers for other 3D software packages should be simple to develop, but do not as yet exist.
SPIERSview can act as a free, multiplatform and high-performance VAXML viewer.
