I'd like to speak with someone who knows the DTS format well

by Leadwerks · in Torque Game Engine · 11/09/2005 (4:51 pm) · 4 replies

I am writing the .dts loader plugin for 3D World Studio. Going by the German docs, and some guesswork, I can now load mesh files up to the primitives. After that, the format stops making sense to me. If anyone has a good knowledge of the format, and is willing to help, please
contact me at josh at leadwerks dot com , and I will send you my MSN screen name.

Thanks.

You should buy Torque and you will have access to loads of info.

Does it include docs on the format?

No but it includes the source code to read and write .dts's which can be used as a "doc". It also includes the dtsSDK (and dtsSDK+) libraries which were designed to allow 3rd party tools to interface more cleanly with .dts.

The problem I am having right now is in the meshes chunk. I got up to the point where I can find the number of primitives, and that is correct, but the data following that seems wrong:

For n=1 To numMeshes
	meshtype=ReadInt(f)
	unknown=ReadInt(f)
	numFrames=ReadInt(f)
	matFrames=ReadInt(f)
	parent=ReadInt(f)
	minx#=ReadFloat(f)
	miny#=ReadFloat(f)
	minz#=ReadFloat(f)
	maxx#=ReadFloat(f)
	maxy#=ReadFloat(f)
	maxz#=ReadFloat(f)
	x#=ReadFloat(f)
	y#=ReadFloat(f)
	z#=ReadFloat(f)
	radius#=ReadFloat(f)
	numVerts=ReadInt(f)
	For v=1 To numVerts
		x#=ReadFloat(f)
		y#=ReadFloat(f)
		z#=ReadFloat(f)
		Next
	numTVerts=ReadInt(f)
	If numtverts<>numverts RuntimeError "numVerts<>numTVerts" 
	For v=1 To numTVerts
		tu#=ReadFloat(f)
		tv#=ReadFloat(f)
		Next
	For v=1 To numVerts
		nx#=ReadFloat(f)
		ny#=ReadFloat(f)
		nz#=ReadFloat(f)
		Next
	numPrimitives=ReadInt(f)
	For p=1 To numPrimitives // Everything is right up to this point

		firstElement=ReadShort(f)
		numElements=ReadShort(f)
		primitivetype=ReadInt(f)

		Next

What the data for each primitive actually looks like, when I write it to a log, is the following bytes (for 2 primitives):
0 0 0 112 0 0 0 112
0 0 0 112 0 0 0 112

The data is always mostly identical bytes for each primitive, though the "112" byte value changes. I don't know what is going on, but up until the primitives, everything is fine, and then all of a sudden the data is totally unrecognizable to me.
