Question The GF 3DO viewer?

Hi,

I recently got a copy of a version of the Grin Fandango 3DO model viewer. And I really like it. But has a version ever been made with full object and texture mapping support? Because that would make it perfect.

And if no, the could the person who made it (I think it was john_doe) please consider making that a feature and releasing it?


Thanks,
James

John is working on adding Grim support to EMI viewer, he has Khalek's specs for GF 3DO's so with a bit of luck it will be in a future version of EMI viewer.

Yeah, I wanted to add support for Grim Fandango files to the EMI Resource Viewer (it already supports GF's BM images).
The thing is I lack time and more important, I know next to nothing about 3D programming and the the current 3do viewer is quite a hack and I'm surprised it showed something that looked right at all

Well, I think if you can't do the 3D part, then you should team up with someone else, and they can help you with the 3D. Because it would be really great with support for 3D, and I would really appreciate it.

I've sent the original source code to Khalek who will hopefully with other people find out the missing parts. Then maybe I can integrate a better 3do viewer.

I'm very tired now and i'm sure that bits of this are wrong but heres my update of the 3do specs:

Code:
4 bytes LE			"LODM"
4 bytes LE			no of materials
32 bytes * num materials	material name
32 bytes			model name
4 bytes LE			geometry set definition
4 bytes LE			number of geometry sets
4 bytes LE			number of meshes


For each mesh do the following
------------------------------
	32 bytes BE	 	mesh name
	4  bytes LE		Shadows
	4  bytes LE		GEOMETRYMODE
	4  bytes LE		LIGHTINGMODE
	4  bytes LE		texturemode
	4  bytes LE		vertices
	4  bytes LE		texture vertices
	4  bytes LE		FACES
	
	VERTICES list * num vertices
	----------------------------
	4  bytes LE (FP)	x	
	4  bytes LE (FP)	y
	4  bytes LE (FP)	z

	TEXTURE VERTICES list * num texture vertices
	--------------------------------------------
	4  bytes LE (FP)	x
	4  bytes LE (FP)	y

	(Vertices * 8) bytes	?
	
	
	FACES list * num faces ?
	----------------------
	4  bytes LE		Material
	4  bytes LE		Type (ExtraLight?)
	4  bytes LE		Geo
	4  bytes LE		Light
	4  bytes LE		Text
	4  bytes LE		Verts //Dunno what/where extra numbers are

	16  bytes		? 		

	24 bytes		?

	Face NORMALS * num vertices
	-----------------------------
	4  bytes LE (FP)	x
	4  bytes LE (FP)	y
	4  bytes LE (FP)	z

	36 bytes		?

	VERTEX NORMALS * num vertices
	-----------------------------
	4  bytes LE (FP)	x
	4  bytes LE (FP)	y
	4  bytes LE (FP)	z
	
	40 bytes		?

	4 bytes LE		number of hierarchy nodes
	
	Hierarchy Mode * num Hierarchy Nodes
	------------------------------------
	64 bytes BE		hnodename
	4  bytes LE		flags
	4  bytes LE		num
	4  bytes LE		type
	4  bytes LE		mesh
	4  bytes LE		?
	4  bytes LE		?
	4  bytes LE		numchildren
	4  bytes LE		?
	4  bytes LE		?
	4  bytes LE (FP)	pivotx
	4  bytes LE (FP) 	pivoty
	4  bytes LE (FP) 	pivotz
	4  bytes LE (FP)	X
	4  bytes LE (FP)	Y
	4  bytes LE (FP)	Z
	4  bytes LE (FP)	Pitch
	4  bytes LE (FP)	Yaw
	4  bytes LE (FP)	Roll
	48  bytes 		?
	4  bytes LE		Parent

	4  bytes LE		child-not always there
	4  bytes LE		sibling-not always there
Still missing is Object Radius, Insertion Offsets, Mesh Radius, extralight, the numbers next to verts(other verts?), the exact relationship between child/parent/sibling and when child/sibling are present.

A GF 3DO Viewer? Where can I get one? Sounds cool!

I got it off LucasHacks ages ago. But that is gone now.

(Is that site coming back?)

I've finally used the source (of Residual) to find out more about the 3do format and rewrote the viewer. It's far from complete and it does little more than the old viewer, except it shows the whole model and not only the single parts.
Now I'm working on implementing textures and, finally, animations.

PS: I'm still looking for someone to help me on the EMI animations.
