This page describes the format of pre-instanced DFFs as used by the mobile GTA games.
Contents
Bin Mesh
The Bin Mesh's chunk format is almost the same as in non-instanced DFFs. The only difference is that the indices are RwUInt16 (as used internally by RW) instead of RwUInt32.
Native Data
The Native Data has no child Struct like on the other platforms and not platform information.
RwUInt32 number of attributes (numAttribs)
#repeat for numAttribs (attribute description)
RwUInt32 attribute index
RwInt32 type (0 = GL_FLOAT, 1 = GL_BYTE, 2 = GL_UNSIGNED_BYTE, 3 = GL_SHORT, 4 = GL_UNSIGNED_SHORT)
RwBool isNormalized
RwInt32 size
RwUInt32 stride (same for all attributes)
RwUInt32 offset
#endrepeat
RwUInt8 data[stride*geometry->numVertices]
Apart from the type, attribute descriptions can be directly passed to glVertexAttribPointer.
Indices
Each vertex attribute in an OpenGL shader has an index. The indices used by the mobile GTAs are the following:
0 - vertex position 1 - tex coord 0 2 - normal 3 - color 4 - vertex weights (only used with skinned geometry) 5 - bone indices (only used with skinned geometry) 6 - extra color (only used with SA's extra color plugin)
Skin
The Skin chunk contains a Struct chunk with the following data:
RwUInt32 platform ID (2 for OpenGL) RwUInt32 number of Bones (numBones) RwReal matrices[numBones][16]
