Pachi's mdl0 is weird as heck. All the string offsets are nowhere near the string

I was just guessing it had to do with bones because the error had to do with the string offset of a bone. So I was indeed RIGHT

I CAME AT YOU BRO. WATCHA GONNA DO BOUT IT
I'm also in a good mood BRO

Btw apparently the TEVs are IN the Materials. I found that out while working on calculating the size of materials (which is done btw)

it's all the string offsets...
not just that one group...

I TOLD YOU!!!

*sigh* I guess we were both right in our own ways -_-*

but you were wrong about telling me to read the string offsets the same way as Brawl's v9 offsets...

now you see what I mean... *sigh*


also...
TEV's are Material Nodes...
Nodes are part of a material, but they can be used between materials...

they do similar work to shaders, but can't handle every specific task...
you should listen to a game developer more often BJ ^_^
lol jk

IK you already do listen to me
shoot... we share info like heck...

What's the diff. between v9 and v11 MDL0's?

well:
the MDL0 header
v11 has extra group offsets
v11 string offsets go past the end of the file (if read as v9)

also it's reported that bone data size is not always the same...

yea... there's quite a few differences...

btw... MDL0 versions range from v8 to v12...
I havn't seen a v12 yet... but it's been reported...

Well a few of the v11 mdl0's I've opened worked fine reading the strings normally. So why the string offset would be different on most but not all v11 mdl0s is strange. I had assumed that the bone data length was longer than usual and possibly had a different header setup, but apparently not. It's just the offset... Now we have to figure out how to read it...

And "Material Nodes" as you call them have their own spot in the mdl0. There's a very similar looking thing kryal calls TEVs inside the material itself, and each one is unique. The shader offset references outside of the material itself. It's kinda hard to explain but there are "Material Nodes" inside the material ALSO.

OMGOMGOMGOMG

see if you can guess what I've just figured out:
http://lh5.ggpht.com/-2dCf4qOJNRc/TftEpDZ5WII/AAAAAAAADG4/1xdZ_32k6Sc/transforms.jpg

I've just figured out how to apply tran- well tbh transforms never really existed =_=
but add the bone matrix to the verts... that's it

not what BJ said:
vert*matrix=value+vert=actual_vert
^nope :3

you know what else that means
subtract the matrix from the verts to build an mdl0

I'm so awsome
and insainly happy

I forgot about the primitives in my last post
added those and here's my function so far:


def setObject( ObjectID, ObjectName, ParentID, PrimitivesList, VectorsList, BonesList ):
    if VectorsList != '' and BonesList == '':
        vert = VectorsList[0]
        normal = VectorsList[1]
        UVs = [VectorsList[2],VectorsList[3],VectorsList[4],VectorsList[5],VectorsList[6],VectorsList[7],VectorsList[8],VectorsList[9]]
        trans_vert = VectorsList[10]
        trans_normal = VectorsList[11]
        trans_UVs = [VectorsList[12],VectorsList[13],VectorsList[14],VectorsList[15],VectorsList[16],VectorsList[17],VectorsList[18],VectorsList[19]]

        error = 0
        if ParentID == '': print 'Object has no parent'
        if vert != '': setVector( vert, 0, 0, ObjectID, 0 )
        else: print 'ERROR: vector object has no Vertices'; error = 1
        if error == 0:
            if normal != '': setVector( normal, 1, 0, ObjectID, 0 )
            else: print 'Object has no Normals'
            if UVs != ['','','','','','','','']:
                for channel, UV in enumerate(UVs): setVector( UV, 2, 0, ObjectID, channel )
            else: print "Object has no UV's"
           
            if trans_vert != '': setVector( trans_vert, 0, 1, ObjectID, 0 )
            else: print 'Object has no Vertice Transforms'
            if trans_normal != '': setVector( trans_normal, 1, 1, ObjectID, 0 )
            else: print 'Object has no Normal Transforms'
            if trans_UVs != ['','','','','','','','']:
                for channel, TUV in enumerate(trans_UVs): setVector( TUV, 2, 1, ObjectID, channel )
            else: print "Object has no UV Transforms"

            if PrimitivesList != '': setPrimitives( PrimitivesList, ObjectID )
            else: print 'Object has no primitives

            setBasicObject(ObjectID, ObjectName, ParentID)
        else: print 'ERROR: Object cannot be logged'
       
    if VectorsList == '' and BonesList != '': pass #TODO
    if VectorsList != '' and BonesList != '': print 'ERROR: object must not contain both vectors and bones'


yes, it's huge, and only 50% complete >_>

I have made progress

>>> setWrite()
tmp set to write
>>> setObject(0, 'test', '', [[[1,1,1],[1,1,1]],'','','','','','','','','','','','','','','','','','','',''], '' )
Object has no parent
'vertices' Vectors for object 0 logged successfully
Object has no Normals
Object has no UV's
Object has no Vertice Transforms
Object has no Normal Transforms
Object has no UV Transforms
Object "test" logged successfully
>>> closeWrite()
tmp sucessfully closed
>>>


here's the TMP data:

< vertices 0 1.0|1.0|1.0/1.0|1.0|1.0
< object 0 test

EDIT: I've also implemented a few errors:


>>> setObject(0, 'test', '', ['','','','','','','','','','','','','','','','','','','','',''], '' )
Object has no parent
ERROR: vector object has no Vertices
ERROR: Object cannot be logged

or

ERROR: object must not contain both vectors and bones

And "Material Nodes" as you call them have their own spot in the mdl0. There's a very similar looking thing kryal calls TEVs inside the material itself, and each one is unique. The shader offset references outside of the material itself. It's kinda hard to explain but there are "Material Nodes" inside the material ALSO.

the TEV is a seperate block...
it's called a shader in Brawlbox
from my reserch on them, I've found structures that compare almost 100% to material nodes

materials themselves don't have nodes...
you have to define a block and link them to the material

shaders are just an extension of the material...
(they exist in every material block)

'Lambert' is a shader

[VILE]

add the bone matrix to the verts... that's it

I said this in the chat ages ago...

I said transforms are mostly bone matricies.

yes... that you did >.>

didn't notice that because you didn't mention the verts XD

EDIT:
how do I get the bone matrix for that vert??

and how come you don't come back to the chat ;_;
we all miss you

Chatango. There is delay with each letter, it's sickening. Get your website back up and I will probably be in the chat a little more.

took an ungodly amount of thought process >:O
the session above doesn't return anything...
that's just to let you know the functions worked...

yes, every line is a seperate function

[ForOhFor Error]

So, what do you have to do now, bones?
And what after that?

[DarkPikachu]

So, what do you have to do now, bones?
And what after that?

well first off, I have to catch up code-wise

but I'm nearly at the bones and weights,
after the bones I'll be able to start on the materials and shaders

then it's the nodes and textures

only then should I actually be finished
I think >.>

I may have missed a few things...

[BlackJax96]

not what BJ said:
vert*matrix=value+vert=actual_vert
^nope :3

I didn't SAY that, that's what KRYAL put in his CODE
Here it is:
        public Vector3 Multiply(Vector3 v)
        {
            Vector3 nv = new Vector3();
            fixed (float* p = _values)
            {
                nv._x = (p[0] * v._x) + (p[4] * v._y) + (p[8] * v._z) + p[12];
                nv._y = (p[1] * v._x) + (p[5] * v._y) + (p[9] * v._z) + p[13];
                nv._z = (p[2] * v._x) + (p[6] * v._y) + (p[10] * v._z) + p[14];
            }
            return nv;
        }

v is the raw vertex position.
nv is the weighted vertex position.
p is the array of 16 values in the bone matrix that the vertex is influenced by.

...I need to figure out how to reverse this btw

[VILE]

Re did the algebra, try this:
( wv.x - (rv.y * m[1]) - (rv.z * m[2]) - m[4] ) / m[0] = rv.x

[DarkPikachu]

hey VILE :/
what are all the values of a matrix??

I tried looking it up... twice...

the best result I got was:
X - 1,0,0,0
Y - 0,1,0,0
Z - 0,0,1,0
W - 0,0,0,1

and then add the values across for the result...

this don't quite work for brbx as the values there (if you stacked them) are:
 W Z Y X
 | | | |
(1,0,0,0),
(0,1,0,0),
(0,0,1,0),
(0,0,0,1)

anyways...
so I need some good notes on a matrix :/

We already talked in chat about all this stuff, but just to post it here for anyone else who wants to know.

3F800000 00000000 00000000 3FC78D50
00000000 3F800000 00000000 4176C5F8
00000000 00000000 3F800000 BED0A3D6

Above is what the typical bone matrix looks like, 12 standard 32bit float values.

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

1 0 0 1.559000015258789
0 1 0 15.423332214355469
0 0 1 -0.4074999690055847

This is what it looks like converted.

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

x - 1 0 0 1.559000015258789
y - 0 1 0 15.423332214355469
z - 0 0 1 -0.4074999690055847

A breakdown of what these values determine:
Red = The iterations of the raw vertex's x position used to calculate the weighted vertex position.
Green = The iterations of the raw vertex's y position used to calculate the weighted vertex position.
Blue = The iterations of the raw vertex's z position used to calculate the weighted vertex position.
Yellow = The additional amount added to total generated by red, green and blue, to make the weighted vertex's position.

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

To apply the transforms with these values, this procedure must be followed:

weightedVert.x = (rawVert.x * matrix[0]) + (rawVert.y * matrix[1]) + (rawVert.z * matrix[2]) + matrix[4]
weightedVert.y = (rawVert.x * matrix[5]) + (rawVert.y * matrix[6]) + (rawVert.z * matrix[7]) + matrix[8]
weightedVert.z = (rawVert.x * matrix[9]) + (rawVert.y * matrix[10]) + (rawVert.z * matrix[11]) + matrix[12]

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

Just thought I should post this so other people can read over it and so I don't forget (haven't archived any of this and I'm pretty tired).

[BlackJax96]

Yo BlackJax96, try these:

v = Raw vertex position
p[] = Bone matrix

v._x = -((v._y * p[4]) - (v._z * p[8]) - p[12]) / p[0]
v._y = -((v._x * p[0]) - (v._z * p[8]) - p[12]) / p[4]
v._z = -((v._x * p[0]) - (v._y * p[4]) - p[12]) / p[8]

or

v._x = -((v._y * p[5]) - (v._z * p[9]) - p[13]) / p[1]
v._y = -((v._x * p[1]) - (v._z * p[9]) - p[13]) / p[5]
v._z = -((v._x * p[1]) - (v._y * p[5]) - p[13]) / p[9]

or

v._x = -((v._y * p[6]) - (v._z * p[10]) - p[14]) / p[2]
v._y = -((v._x * p[2]) - (v._z * p[10]) - p[14]) / p[6]
v._z = -((v._x * p[2]) - (v._y * p[6]) - p[14]) / p[10]

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

I just did some simple algebra to reverse the equation, I only tested the first 3, but they should all work.

None of them worked :/
- I need to get from the weighted position to the raw position. Where is the weighted position in those equations...?
- This is the matrix in brawlbox, just so you know:
0, 4, 8, 12 = X
1, 5, 9, 13 = Y
2, 6, 10, 14 = Z
3, 7, 11, 15 = W

[DarkPikachu]

from what VILE discussed with me... there's only one logical way I can see to do this:

                nv._x = (p[0] * v._x) - (p[4] * v._y) - (p[8] * v._z) - p[12];
                nv._y = (p[1] * v._x) - (p[5] * v._y) - (p[9] * v._z) - p[13];
                nv._z = (p[2] * v._x) - (p[6] * v._y) - (p[10] * v._z) - p[14];

there would be no division...

if it's not that, then shoot me XD

EDIT: btw, I think I finally understand C-type coding
and the reason you get inverse values when reading

the way it reads would basically be:

returned_value = ''
file = list('MDL0') #['M','D','L','0']
for byte in file: value += byte
print returned_value

>>> 0LDM

where:
file would be the file you're reading from
byte would be the current byte the program is on
and returned_value is, in all obviousness, the returned value being read

so that's a simple python program that reads like a C-type compiler

python actually returns the value as it looks in the file
