View Full Version : The GF 3DO viewer?

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?

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.

That is great!

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:

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 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?)

And last I talked to Tomas, he was working on redesign and stuff, so... :) Goody, goody! :)

Sorry for bumping an old topic, but....

Any progress on any of this? No one has saod anything in this forum for ages.

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.
