Default Omens Of War .TER File Format
I've started reverse-engineering the .TER file format that's used in OoW zones and what follows is my progress thus far.

The header is as follows:

Code:
struct Header {
  char magic[4]; // Constant at EQGT
  uint32 unk1; // Seems constant at 2... version?
  uint32 list_length; // This is the size of the object/property list that follows
  uint32 object_count; // This is the number of objects in the list (NOT the number of elements total)
  uint32 vertex_count; // This seems to be the count of vertices in the mesh.
  uint32 poly_count; // Seems to be the count of polygons in the mesh.
};
After the header comes a list of objects and their properties.
Each element is a null-terminated name followed by a null-terminated value.
If the name starts with 'e_' it is a property of the previous object named, otherwise it's naming a new object and its associated base texture.

For example, the list for wall of slaughter is:

I'll post more as I figure it out.

Happy Hacking,

Edit #1: Added the object_count element to the struct.
Edit #2: Replaced uint32 unk[2]; with the vertex_count and poly_count fields. Put the struct in code brackets.

You can also get a proper view of it at http://home.archshadow.com/~daeken/t...tress_objs.txt

This is the debug output of my python script for decoding these files, so it's a bit messy still hehe.

Ok... figured out more.

After the list comes the vertices.

The struct for each vertex is as follows:

Code:
struct Vertex {
  float unk1, unk2;
  float x;
  float unk3;
  float y;
  float unk4;
  float z;
  float unk5;
};
I'm working on figuring out triangles now, and then I'll work on figuring out the unknown values. My guess is that 3 of them are normals, 2 are tex coords.

Well, I just got zone geometry rendering perfectly, albiet without textures (it's figured out, just not coded as of yet)

It was very, very simple.

Code:
struct Header {
  char magic[4]; // Constant at EQGT
  uint32 version; // Constant at 2.
  uint32 list_length; // This is the total length of the material list that follows
  uint32 object_count; // This is the number of materials in the list (NOT the number of elements)
  uint32 vertex_count; // Number of vertices
  uint32 poly_count; // Polygon count
};
After the header comes a list of materials and their properties.
Each element is a null-terminated name followed by a null-terminated value.
If the name starts with 'e_' it is a property of the previous material named, otherwise it's naming a new material and its associated base texture. If the base texture named starts with e_, leave the base texture empty and treat this name as its own variable. In the case of having no base texture, simply use the first e_ entry value as the texture, but make sure you also set the e_ entry in your material data.

Now comes the one portion of the file that I have yet to figure out. My theory is that it is a BSP or octree, but I have yet to test it. To skip it, seek to 3 + (vertex_count * 32) + (poly_count * 20) bytes before the end of the file. I'll work on figuring this out when I get a chance, but my knowledge of BSPs and octrees is so limited its not even funny.

Next comes the vertices. You should decode these and store them in a zero-indexed array.

Code:
struct Vertex {
  float x, y, z; // Vertex location
  float i, j, k; // Normals?
  float u, v; // Tex coords, clamped to [0,1]
};
After that comes the triangles. The v0, v1, and v2 fields index the vertex array. The group field indexes the object type list if greater than or equal to zero, else it means the object is invisible I _think_.

Code:
struct Triangle {
  unsigned long v0, v1, v2; // These are vertex indices
  signed long group; // Texture/material group id.
  unsigned long flags; // This seems to flag if you can walk through the polygon or not.
};
Then after that is simply 3 null bytes, then the end of the file.


Enjoy

God anguish looks beautiful running in the python version of my ter decoder with full textures

I got it working in about 10 minutes without having to change the file loader... everything was right on the first try

I would take screenshots, but unfortunately GLUT doesn't want to let me go windowed... Whatever. I'll have the C version rendering .ter soon anyhow

I will post screenshots ASAP.

Anguish works great in my renderer but I can't display "riftseekers" at all. I have a problem loading the texture names from the strings at the start. The names seem to get out of step. Does it work for you?

And if so could you try to explain how to get the names decoded properly if you have the time

Thanks

I updated the guide (not the parent post, but one of the comments) to fix the material loading... basically, all you have to do is make sure that the base texture given isn't an e_ entry

Thanks - I'm still having trouble with this though. I think I'll do what you appeared to have done based on your post and write a decoder in python as it's so much easier to prototype stuff and then when it works recode it in c++.

I've had a closer look at the materials information and believe it should be formatted like this (just an extract from the riftseekers zone)

Code:
cieling
	e_fShininess0		
	Di_ct_pyrilen_ceiling_c.dds	e_TextureDiffuse0
 	Di_ct_pyrilen_ceiling_8_n.dds	e_TextureNormal0
	Opaque_MaxCBSG1.fx

wall high
	e_fShininess0
	Di_ct_pyrilen_wall_high_c.dds	e_TextureDiffuse0
	Di_ct_pyrilen_wall_8_n.dds	e_TextureNormal0
	Opaque_MaxCBSG1.fx


red potion
	ra_crystowlava01_e.dds		e_TextureDiffuse0
	ra_crystow_water_n.dds		e_TextureNormal0
	ra_crystow_water_e.dds		e_TextureEnvironment0
	e_fFresnelBias
	e_fFresnelPower
	e_fWaterColor1
	e_fWaterColor2
	e_fReflectionAmount
	e_fReflectionColor
	Opaque_MaxWater.fx

silver
	e_fShininess0
	Di_ct_gelidran_silvermetal.dds		e_TextureDiffuse0
	Di_ct_gelidran_silvermetal_spec_8_n.dds	e_TextureNormal0
	Opaque_MaxCBS1.fx
It seems to start with a name and end with an effect and contain a number of effect parameters start with e_ which may or may not have a parameter before them in the file. Pretty much what you had except that there seems to be an e_TextureDiffuse0 texture for all of them which I guess will do as a base texture for the material for simple rendereing.

The effects exist as files in the RenderEffects directory on disk. I would guess that they might be encoded directx effects files and the material information in the TER file describes the parameters to them.

*blinks* Um... you're right... congrats... lol

Damn man... I can't believe I didn't see that before. Nice work

Now I can get riftseekers to load properly.

Just using the diffuse textures it comes out all blue and orange. I wonder if it really looks like that.

Dranik zone looks like this with my renderer


Still some work to go on the textures I think. They almost look scaled wrong although it could just be that simply rendering the diffuse texture isn't enough to get a reasonable output.

Looks like you may be using the wrong mipmapping level perhaps? I dunno... m'be the bump mapping is neccesary to make it look good...

Ah, good guess
Setting anisotropic mipmapping mode made it look far better
