(BMD) Binary Model Data - File Format

The BMD file format is a byproduct I created in 2013 to help me manage 3d mesh data extracted from various sources. It's derived from Valve Software's SMD (StudioMDL Data) file format. The idea was to have a bare bones very simple binary file format to store mesh data that had the ability to contain skinning information and bone data.

Features

Simple straight forward file format which contains the basic core components like an primitive list
Can contain multiple meshes
Ability to store an amature (skeleton rig)
Deformation/Skinning information (how the bones deform change the mesh)
Material list (Information on how the mesh is textured)
Ability to store meta data

Whats included?

Noesis Plugin

plugins\Noesis\fmt_BinaryModelData_bmd.py Is a plugin for a popular model viewer called Noesis.

010Editor Template

plugins\010Editor\BMD_Format.bt Used by my favrioute hex editor 010Editor to help visualize the file format.

3DSMax Plugin

plugins\3DSMax\2012\BMDImport.dli Dated 3DSMax 2012 plugin for importing/exporting the file format.

BMDConvert

Located at: tools\bmdconvert.exe is a tool you can use to test convert some files to the BMD file format.

Usage: bmdconvert -f [FormatType] -x [UpAxis] --src path/to/source path/to/out
Format Types: OBJ,SMD
Axis: Y or Z
Example: bmdconvert -f OBJ -x Z --src O:/geom/Teapot.obj O:/geom/cTeapot.bmd

Improvements & Ideas

Store more information about the mesh (PBR materials?)
Compress triangle list or reference same value vertex floats
?? (You can help decide)
