MD3 is a model format developed by id software. It is used by the Quake 3 engine as well as its many successors and other game engines including Darkplaces.

The format is used mostly for player/NPC models and non-structural geometry although it may be used for structural uses.

In Blood Omnicice, MD3 is general format used for non-animated models.

Features

• Vertex-based animation
• Multiple surfaces (meshes) per model
• Float precision for vertices (almost no wobbling)
• Can support a very high amount of triangles.
• Support tags (volumeless vectors) which is light form of bones and used to attach together separate models and mark positions.

Limits

• Max 65536 vertices
• Max 32768 triangles
• Max 65536 frames
• Max 256 meshes
• Max 256 skins
• Vertex normals are stored as pair of byte angles (pitch and yaw)
• Not supporting smoothing groups (to simulate SG, mesh should be shopped in a parts)
