Blitz3D Model (.b3d)
The B3D file extension stands for Blitz3D Model, used primarily in the Blitz3D programming language for creating 3D video games. Introduced in 2001 by Blitz Research Ltd., Blitz3D extended the capabilities of its predecessor, BlitzBasic, by incorporating a DirectX 7-based 3D engine. B3D files store 3D model data, including textures, vertices, meshes, bones, and animation information, in a chunk-based format. These files are essential for defining in-game characters, terrains, buildings, and other objects, making them a crucial component in game development. Blitz3D's ease of use and flexibility have made it a popular choice among game developers, despite being considered somewhat outdated compared to modern 3D engines.
