I wrote a Quake 3 MD3 loader for kicks this weekend and figured people might have use for it in their own projects. I made no attempt to integrate it with Panda’s own loader.loadModel or Actor, but it works well even so.
You can download it here:

There are several files:* md3.py is the meat of it.
- lerp.sha is a Cg shader to do interpolation during animation.
- invalid.jpg is a texture to load when a texture file for the model can’t be found.
md3.py contains several classes:* md3.Model will load and handle a single MD3 model. It will also attempt to load textures if they are specified in the surfaces. - md3.Animation is used to animate an MD3 file.
- md3.Player combines the other two to facilitate loading a standard Quake 3 player model, the associated .skin files, the animation.cfg file, and can be used to animate the model.
An example for loading a player model would be:
from direct.directbase import DirectStart
from direct.interval.LerpInterval import LerpHprInterval
from direct.showbase.DirectObject import DirectObject
from direct.task.Task import Task
from pandac.PandaModules import *
import md3
base.disableMouse()
base.camera.setPos(0, -200, 0)
class Test(DirectObject):
def __init__(self):
self.player = md3.Player("models/players/visor")
self.player.reparentTo(render)
self.player.play("upper_attack")
self.player.play("lower_walk")
self.player.setSkin("blue")
self.weapon = md3.Model("models/weapons2/grenadel/grenadel.md3")
self.weapon.reparentTo(self.player.find("**/tag_weapon"))
LerpHprInterval(self.player, 10, VBase3(360, 0, 0)).loop()
taskMgr.add(self.update, "update")
def update(self, task):
self.player.update()
return Task.cont
Test()
run()Tags in the MD3 models are handled as nodes, and you can use model.find() to get ahold of them, as above with the weapon model. If you reparent your nodes to the tag it will transform your node with the tag as the model animates.
Available frames of animation for the player are:
both_death1
both_dead1
both_death2
both_dead2
both_death3
both_dead3
upper_gesture
upper_attack
upper_attack2
upper_drop
upper_raise
upper_stand
upper_stand2
lower_walkCrouch
lower_walk
lower_run
lower_back
lower_swim
lower_jump
lower_land
lower_jump2
lower_land2
lower_idle
lower_idleCrouch
lower_turnCaveats:* The code doesn’t understand .pk3 files, so extract any models you want to use, along with their textures and models.
- Neither does the code understand Quake 3’s .shader files. Only simple texturing is supported by this code. The lerp.sha file only handles a single texture.
- Since it’s using the shader, lighting doesn’t work.
- As I write this I realize I forgot to add support for reversed frames in animation.cfg.
I’ll write some detailed documentation as time permits.
