Fileformat: binary little endian

MMF-File ::= Header (char[4] “mmf”+chr(13) ), uint32 version (currently 0x01), DataBlock * (one VertexBlock and one IndexBlock), EndMarker (uint32 0xFFFFFFFF)

DataBlock ::= uint32 dataType, uint32 dataSizenr of bytes to be jumped to skip the block (not including dataType and blockSize value), uint8 data[dataSize]

DataBlock ::= VertexBlock

DataBlock ::= IndexBlock

VertexBlock ::= Vertex-dataType (uint32 0x00), uint32 dataSize, VertexAttributeDescription , EndMarker (uint32 0xFFFFFFFF), uint32 vertexCountthe number of vertices in the following datablock, uint8 vertexDatathe vertex data

VertexAttributeDescription ::= uint32 attrIdone of the constants: 0x00:POSITION (attribute name: “sg_Position”) 0x01:NORMAL (attribute name: “sg_Normal”) 0x02:COLOR (attribute name: “sg_Color”) 0x06:TEX0 (attribute name: “sg_TexCoord0”) 0x07:TEX1 (attribute name: “sg_TexCoord1”) 0xff:custom attribute MMF_CUSTOM_ATTR_ID uint32 numValuesentrysize of the vertexattribute specified by index, uint32 (=GLuint) typetype of the vertexattribute specified by index, uint32 extLengthlength of the extension for future use, VertexAttributeExtension* (extensions for the vertex attribute)

VertexAttributeExtension ::= uint32 extension Type uint32 dataLength uint8 data[dataLength]

VertexAttributeExtension ::= VertexAttributeNameExtension

VertexAttributeNameExtension ::= uint32 extension Type 0x03 ( MMF_VERTEX_ATTR_EXT_NAME ) uint32 length of name string including padding zeros uint8* attrName (filled up with additional zeros until 32bit alignment is reached.

IndexBlock ::= Index-dataType (uint32 0x01), uint32 dataSize, uint32 indexCountthe number of indices in the following datablock, uint32 (=GLuint) indexModethe meaning of the indices (GL_TRIANGLES, GL_TRIANGLE_STRIP, …), uint8* indexDatathe index data
