right, but I'm skipping two floats. Hence, the eight.

for the high value did you try without the multiply by 1000.

No, I haven't tried removing the 1000. But it won't matter at the moment, as that part of the code is not used before the app dumps. The *first* problem is totalFrames and numJoints are incorrect values, so, as I am reading in joints in the for loops I run out of bounds in the byte array.

ok, I think I have localize the bug, there is a bug in sully implementation of MS3DMaterial, it assume that the texture name is always 128 bytes long and use a System.arraycopy for copying from the buffer to m_texture.
And because Material Texture loading was the last operation it doesn't bug. But if you continue the process as you do, the pointer is wrong.
To bypass that you need to find the filename length, and change two arraycopy and also the MS3DMaterial sizeof according.
Not enough time to test, but I think it would do the job...

Well, after further investigation, it looks like 128 bytes are allocated for the texture and alpha map. Whether or not the texture name fills this does not matter.
So, I don't think that is the problem. I'm wondering why in the original loader the byte array was not just wrapped in a ByteBuffer and then use .getFloat(), .getShort(), etc on it.

Ya, you need to rewrite all.I think i will do that,.
I found another bug in loadModelData changed to:
code changed to
boolean loadModelData(InputStream is, long filesize)
{
// wrap a buffer to make reading more efficient (faster)
DataInputStream dis = new DataInputStream(new BufferedInputStream(is));
int fileSize = (int) filesize; // Warning! File size trunctuated to 32bits!
byte[] pBuffer = new byte[fileSize];
try
{
dis.readFully(pBuffer);
dis.close();
}
catch (IOException ioe)
{
System.out.println("MilkshapeModel Error: Failed to read file contents.");
ioe.printStackTrace();
return false;
}
...

Ok, I am going to try starting again using ByteBuffer and see if I have luck with that. I'll keep you posted. If you want to continue working with the current version, that'd be good too.

ok, for the model that you are trying to load, could you give it to me? The best for such a problem, is to use in the same time a hex editor, and find the faulty bytes (and know how little and big endian works)

Ok, I have completely rewritten the loader. I'm now loading the mode and displaying it fine. I'm going to start loading the joints now. Using the ByteBuffer has been much easier. I'm able to follow the spec directly and read just as it says. Hitting the joints now...

Alright! Works. Here is the complete loading code. My apologies for the length. You may notice I changed some things, mostly I am trying to move away from using the MS3D* classes in favor of just the generic ones. Which means I changes the generic ones a little bit. 1

Hey Mik,
Don't know if you are still interested, but I've put aside the Milkshape Animation for a moment and I am moving on to Quake 3 Loading and Animating. I am successfully loading all the Milkshape data (joints and all) but having trouble getting them to animate. My hope is to write a Quake 3 loader and get that animating and that may help me with the Milkshape. My design is such that the loaders build a common model anyways.
I'd still be interested in your progress though. So, let me know if you have any luck.

Hi mik and mojo.
I've also started on a bones animation project for ms3d.
Did u guys finish your or did you move on to mdl loaders? Anyway my program loads all the data and setups the joints correctly. Just gona battle it out some more with the Quartenions and the timer stuff and hopefully it will work. Right now it displays the image but no animation. Also I want to separate the animation from the model file and insted load in animation files like smd.

I got as far as loading the joints, and then moved on to MD3. I was having problems with my joint translations, causing the vertices to be totally put out of whack. If you get a loader done, I'd love to see what you did for animation.

I used the same tutorial Tarm. Wich Timer did you use?
My app runs but its looks like shit... vertices and stuff everywhere...
I wonder if it is the timer that is wrong. Which model have you tested it on?

Remember that c++ uses pointers, porting from c++ to java isn't always very easy. If you get vertices at very odd places it might be because you are passing on a reference to a method when you need to copy the value instead. |

Im using a model called fantasy. Its basicly just a head with headspikes growing out of it as an animation. Its good for testing as it is quit simple. The animation works but the spikes seem to grow in the wrong direction.. coming out under the head instead of ontop of it.
This could surely be a reference problem that Tarm was talking about. God knows I have been known to get into trouble with pointers.
I could also be an matematichal error, maybee my slerp funtion in Quarteninons is faulty or something.
Anyway, gona look at it tonight when I come home from work.
Be well guys.

Can I get some help please?
The loader won't work for me as it's missing some TGAImage class...
Do I really need to reinvent the wheel and code my own loader:'(

I messed a little with my postMulty method and now my models look good except that nothing gets animated... very strange.
Maybee there are some strange stuff in my Matrix/Quart classes. idont know.

Just reviving an old thread here  I am currently in the process of creating a loader for JOGL using the GL4JAVA port of Nehe lesson31 as a basis for my loader. I have completed the loader but when I try to animate the Model, the Model seems to explode outwards with vertices every where. When I remove the animate function the model loads thing with no Animation. Did anybody complete their Milkshape Loader with Skeletal Animation ? If not can anybody have a wee look at my Animation code and see if i have made any mistakes. 1

Thanks in advance *****EDIT****** Heres a screen capture of my app running with the Animation function taken out http://www.honours.pwp.blueyonder.co.uk/noAnim.jpgWith the Animation function put in http://www.honours.pwp.blueyonder.co.uk/probVertsEverywhere.jpg*************Another edit********** Messed about with my animation function, got some sort of animation but it seems like the had is coming out of the models chest and the arms and legs look weird http://www.honours.pwp.blueyonder.co.uk/probsweirdAnim.jpgMaybe a problem with my Matrix class or Quaternion class |
