NEW GZDoom tool called md2modeldef

[CBM]

Hi..

I was wondering if there might be some usefull applications out there that can do one or more of the following:

1) automatically write modeldef code for a given md2 model

- could be done by reading the MD2 file and getting the list of animations as well as framecount etc then output to a text file

2) automatically convert an OBJ file to an MD2 file with animations (standard humanoid Quake 2 animations)

- could be done by making it look for groups with names such as "RightLegUpper1...n", "RightLegLower1...n", "RightArmUpper1...n" etc
- then make it create a number of frames where it moves and/or rotates the meshes in the groups according to some predefined pattern

3) automatically combine textures to a single texture and update texture coordinates?

- could be done by reading all materials and their images, then create a new image and update materials and texture mapping

I am looking in to some c code that should be able to load MD2 files, when I figure out how to get all dependencies installed correctly and it compiles with GCC, then I am going to experiment with the above if no such tool(s) exists yet

[Kinsie]

1.) There isn't.
2.) OBJ files don't have animations, and Quake 2 doesn't have skeletal animations, so there's nothing here to work with.
3.) I dunno.

I Know obj files do not have animations and that md2 only support mesh based animation

Some tools can Translate skeleton anims to mesh anims though

But

If the obj was Edited such that limb meshes were in groups with predefined Known names, then a humanoid mesh could be animated if the tool read ie an xml file that could specify how to make an animated md2 model from a static obj file

An xml that specify the changes needed on a frame by frame basis

Lets Say the tool want to make a Walk anim

It then could read an xml that tells it that the meshes in Group RightLegUpper and RightLegLower and RightFoot must make the following movements and so on ...

That could Also aloow for using the same animation def for multiple similar static objs

Just like skeletal animations

[Kinsie]

That's a lot of effort to try and get out of rigging a model rip you found on models-resource up to a skeleton.

True

And it Will take Some time

My first goal is to make the tool able to output a modeldef when fed an md2 file

....that Should be easy

I got the md2 example code Running in gcc today

[Graf Zahl]

Why MD2? Unless your data is already in that format, stay away from it, the vertex resolution is far too low for any decent result.

[Enjay]

Absolutely. MD2 has awful vertex resolution - saving the model will usually end up with vertices moving versus what you could see in the editor and all your nicely placed fine details will just end up looking a mess.

Even more, if the model is animated, vertices can wobble around all over the place between animation frames - even if it is a vertex that isn't supposed to move, another part of the model moving can cause wobble in the supposedly stationary one. And, again, it doesn't usually become obvious until you save and by that time it may be too late.

[CBM]

well

MD2 has named animations and it is easy to read.. plus I have a lot of md2models stored (mainly old Q2 player models)

and it seems there is a gap regarding tools targeted at using models with GZDoom

the MD2 reading source code example I found was easy to use (had to throw out the rendering stuff though since I could not get it satisfied with all dependencies.. but thats ok.. it is not for displaying models anyway)

I might do an MD3 version once I get this tool to function as I need it to

it can display a header now.. yaaay

next step.. to make it write out a modeldef to fit the MD2 model

MD2 has named animations and it is easy to read..

True, and that is one of the few advantages that MD2 has.

But to illustrate the level of inaccuracy in the format, here is the Ravenclaw from Jedi Outcast in MD3 format:



And here is the same engine saved in MD2 format:

[CBM]

yes okay, that is .. not optimal

I found some MD3 information on the website for Maverick

https://www.icculus.org/homepages/phaet ... ormat.html

could be interesting to make a plugin for maverick that could output a suggestion to a GZDoom modeldef

[CBM]

quick update..now it can yell at you for feeding it md3 models

Code: Select all • Expand view

C:\gcc-prj\md2modeldef\bin\Debug>md2modeldef.exe upper.md3
Error: bad version or identifier
Quake 3 model identifier

C:\gcc-prj\md2modeldef\bin\Debug>


I think I might make it a tool to handle both md2 and md3... once it can actually do something usefull... I will make a thread about it in the appropiate sub forum (software and ports?)

[CBM]

update... now it can read md2 frame names

Tool is now able to read md2 files and write modeldefs

Next .. Adding md3 support

---------------------

texture is read from MD2 file

path is read from MD2 file (path to texture, usually models\players)

spritenames are generated from animation names (yes yes... non animated MD2 models will not work, but this is not a tool for models without animation)

max number of animation sets is 10 in GZDoom apparently... so it skips some animation sets if there are more than 10, usually there are 16

resulting file is named texture name + .modeldef

jumps are handled as a "seperate" animation set regarding spritenames

spritenames are ... first 3 lettes of the animation set name plus a number

(numbered in packs of 10, usually long animations such as stand will be up to 40 frames.. ie... walk0-3 A-J)



If the numbering increases by more than 2 then I interpret that as a jump, so a jump from walk109 to walk201 would be detected



if the input file is named tris.md2 then the tool assumes there is a weapon.md2 with a weapon.pcx texture as well



example output could be

wal0 A 0 "walk01"

for tris.md2 and

wal0 A 1 "walk01"

for weapon.md2



ie. spritename spriteindex modelindex framename


only problem is if 2 or more animations have the same 3 letters in the name of the animation set.. ie... crwalk and crwobble would both begin with crw


I will post more details later today
