i made lugin for Noesis

start simple.

Code: Select all

def noepyCheckType(data):
	bs = NoeBitStream(data)
	file = bs.readUInt()

	if file == 0x42A14E65:
		return 1
	else:
		return 0

This part of code check my file (0x654EA142), dunno why it should be at inverse in the function

[shakotay2]

Little endian data definition: a value of 0x1234ABCD for example is CDAB3412 in the file(s). Don't ask me why, accept it.
(In big endian formats the value would be stored as 1234ABCD, surprise. High word (1234), then low word (ABCD) so humans can read it without headaches .) If they know hex.

[moonpaladin]

Code: Select all

def noepyLoadModel(data, mdlList):    
    ctx = rapi.rpgCreateContext()
    bs = NoeBitStream(data)
    
    
    #rapi.rpgClearBufferBinds()
    bs.seek(0x20DC, NOESEEK_ABS)
    vertsCount = bs.readUInt()
    faceCount = bs.readUInt()
    bs.seek(0x44, NOESEEK_ABS)
    uvAddr = bs.readUInt()
    uvAddr += 12
    bs.seek(0xB4, NOESEEK_ABS)
    FIaddr = bs.readUInt()

    bs.seek(0x12C, NOESEEK_ABS)
    VertBuf = bs.readBytes(vertsCount * 12)
    bs.seek(uvAddr, NOESEEK_ABS)
    uv1Buf = bs.readBytes(vertsCount * 8)
    bs.seek(FIaddr, NOESEEK_ABS)
    idxBuf = bs.readBytes(faceCount * 12)
    
    
    rapi.rpgBindPositionBufferOfs(VertBuf, noesis.RPGEODATA_FLOAT, 12, 0)
    rapi.rpgBindUV1Buffer(uv1Buf, noesis.RPGEODATA_FLOAT, 12)
    rapi.rpgCommitTriangles(idxBuf, noesis.RPGEODATA_UINT, faceCount*3, noesis.RPGEO_TRIANGLE, 1)

    mdl = rapi.rpgConstructModel()
    mdlList.append(mdl)

    return 1
    

Still trying to understand what is bs.seek and the rpgCommitTriangles

[shakotay2]

Long way to go - google for python seek()

Noesis functions to be found in pluginshare.h (see pluginsource.zip)
void (*rpgCommitTriangles)(void *idxData, rpgeoDataType_e dataType, int numIdx, rpgeoPrimType_e primType, bool usePlotMap);

It's to understand the parameters only - keep in mind that .h is a C header file.
(Dunno whether there's a commented Noesis python functions parameter list, but the above should do.)

Still trying to understand what is bs.seek and the rpgCommitTriangles

"bs" - NoeBitStream()
"seek" - sets the position within the current stream.
(NOESEEK_REL-from current position and NOESEEK_ABS- from the beginning of the file)
"rpgCommitTriangles" collects faces from bytes (args=bytes for index buffer, dataType, numIdx, primType)

in files (00000726.dat) and (000000000000c4fe.dat) have swapped vertices with faces.
using the (iSize and vSize) it can be easily solved.

"seek" - sets the position within the current stream.

Yep! but is the position I have been using in the hex2obj is slighty different so need to know why I need to use different values there, gonna review your script.

Yep I was worried for it too, but seems that for someone skilled doing scripts is a very easy xD, thanks for it, gonna learn the basis with this script, I know these models are basic because it have a very easy pattern. Again thanks and sorry for so many requests.

There is a nice tutorial on how to make a noesis script describing this exact thing in my server. You must of left it.

[moonpaladin]

Well there is much to learn

Code: Select all

def noepyCheckType(data):
    bs = NoeBitStream(data)
    if bs.readInt64() != 8391166444416618085:
        return 0
    return 1

At least are some values that I'm understanding like these one
eN¡Blist : 7473696C42A14E65 = 8391166444416618085

The other value that I'm not sure is :

Code: Select all

 bs.seek(16, NOESEEK_REL)

According about your descripction (current position) should be this?


and how about the

Code: Select all

bs.seek(64, NOESEEK_REL)

and

Code: Select all

bs.seek(4)

So in order that the script load the other type of mesh , I need to change the noepyCheckType to it can load the other type of .dat file and change that iSize and vSize, is listed in the script but is not being used yet

Good to know , I was checking the chrrox tutorial

[moonpaladin]

Well is really weird I'm getting around four different types of errors xD, and this meshes have same pattern, I tried to tweak the script a bit to it not thrown error but still getting errors, or is my noesis? I had this kind of "C error" time ago :salty:

position is the same.

not so simple.

eN¡Blist : 7473696C42A14E65 = 8391166444416618085

"def noepyCheckType(data):" and "def noepyLoadModel(data, mdlList):"
two different methods that noesis calls in turn.
the first one is to check the file the second one is to load the model.
in each of them a new thread is assigned "bs = NoeBitStream(data)".
so the position starts from the beginning of in every new stream.

in general, the header in the file is:(eNЎB)
but since there are inverted files i check the first 8 bytes(eNЎBlist) by reading the integer64 value.

use debug. eg: print(bs.getOffset()). will print the current position.

i tried to tweak the script a bit to it not thrown error

what did yout ried to tweak there?
I'm already annoyed by these "broken" files
(there may be extra null bytes in the same places. Because of this, checks have to be made.)

one of the problems solved:
At the end of the file, information is not only about faces and vertices, there may also be materials.
(indentation is now used using (iSize и vSize)

(you need to immediately do a normal unpacker so that you don’t suffer with models later)

[moonpaladin]

This one is really helpfull! xD

I'm already annoyed by these "broken" file

I get it, I don't want to see these .dat files again for a while

(indentation is now used using (iSize и vSize)

Thank you Durik!

[Durik256]

in files (00000726.dat) and (000000000000c4fe.dat) have swapped vertices with faces.

final , support swapped model.
(I did not bother, I just duplicated the reading of faces and vertices and swapped them.)
