What is a .lwo file?
model/x-lwo
LWO is the LightWave Object format for polygonal geometry, surfaces, vertex maps, clips, and layer data. Modern LWO files use an IFF-style FORM container with big-endian chunk identifiers and lengths; geometry is split across point, polygon, tag, and surface chunks that a reader must reconnect.
How to use a .lwo file
Use an example .lwo file to test FORM and chunk boundaries, big-endian numeric decoding, point and polygon indexing, surface-tag assignment, and safe rejection of a chunk whose declared length exceeds the file.
