Script help

Hello.

Plz. On python for Noesis64
Mesh import plugin
class MeshInfo:
# Infomations from 0x0400 Chunk
def __init__(self, index, name, numOfFaceChunk, parentID, indexOf0x0500Chunk, indexOf0x0600Chunk):
self.index = index # Global Index
self.name = name
self.numOfFaceChunk = numOfFaceChunk
self.parentID = parentID
self.indexOf0x0500Chunk = indexOf0x0500Chunk
self.indexOf0x0600Chunk = indexOf0x0600Chunk
self.initialize0x0600ChunkInfo()
self.boneMap = None

def initialize0x0600ChunkInfo(self):
self.indexOf0x0800Chunk = []
self.indexOf0x03000201Chunk = []
self.faceCount = []
self.faceIndex = []
self.texture = []
what is indexOf0x0800Chunk and indexOf0x03000201Chunk and why 0x0800 and 0x03000201.
How this work and what is it ?
Same for indexOf0x0500Chunk and indexOf0x0600Chunk why this variables are named like that ? First time i see this.
Maybe something similar on C# ?

It's just names variable and methods

Yes. Thank you. It's not a problem anymore.
But i have new questions...

What is this

linkedBone = linkedBone[:len(weight)]

and

linkedBone = [boneMap[x]-1 for x in linkedBone]

I cant understand this pieces of code.

I'm trying to find something similar in c++, but I can't figure out what it does

Ok.

Code: Select all

linkedBone = [boneMap[x]-1 for x in linkedBone]
it is

Code: Select all

     int LB = 0;
     foreach (int x in linkedBone)
     {
            linkedBone[LB] = boneMap[x] - 1;
             LB++;
     }
right ?
but what is linkedBone = linkedBone[:len(weight)]
[:] ok. its a slice. So from 0 to weight.count each 1.....lol.
So we delete info in linkedBone after len(weight) right ?

linkedBone.RemoveRange(weight.Count, linkedBone.Count);.

len(weight) - this list length weight.Count or (array) weight..Lenght
[:] - this slicing list/array [from which element: to which] - ([1:3] - from 1st to 3rd)
*(in this case, I don’t know what your type WEIGHT is, I will count it as INT)

Code: Select all

List<int> weight = new List<int> { 1,2,3 };
List<int> linkedBone = new List<int> { 4,5,6,7,8 };

linkedBone.RemoveRange(weight.Count, linkedBone.Count - weight.Count);
out: (4,5,6)

linkedBone.RemoveRange(weight.Count, linkedBone.Count); ==== >

yes thank you . Its a "count" and not "end index" =)

Wat does NoeVertWeight(linkedBone, weight) ?

Any Noesis Documentation ?

NoeVertWeight - vertex weight. it binds the vertex to the bone using the weight
a vertex can be affected by multiple bones. eg 1 or 8
contains: (as many vertices)
indices = array INT index bones
weights = array FLOAT weight
*(number of indices and weights should match)

share the original script, why are you doing this?

I try to port noesis Plugin (model loadinging) script to Unity3D.
I can load models in unity now with textures and materials.
Now i try to adding bonnes and weight to vertex.

original script https://github.com/Team-Alua/GR2-gfx-ex ... _GFX_V2.py

if this is for unity, then why do you need c++?

You load instantly information in weights.
Thank you. But i prefer just stock information and assigne this Data at the end.

but why they do this

Code: Select all

 linkedBone.RemoveRange(weight.Count, linkedBone.Count - weight.Count);
linkedBone count is always = 4 cause
for (int ii = 0; ii < 4; ii++)
linkedBone.Add(r.ReadUInt16());
... so this line is useless.

adn why they remove the first index from weight

Code: Select all

 try:
            weight.remove(0)
        except:
            pass
or try = just try without execute the code. And if impossible just continue to the next Vertex ?

so if(weight.count == 0)
continue;

no, this is an attempt to remove zero. if he is (zero weight)

*(do what you want, i just suggested)

something like this, I don't think it should be done, share which model you are load in unity

Code: Select all

void loadMeshWeight(int vertexCount, List<int> boneMap, yourBinaryReader br)
{
    BoneWeight[] weightList = new BoneWeight[vertexCount];
    for (int i = 0; i < vertexCount; i++)
    {
        float[] weight = new float[4];
        int[] linkedBone = new int[4];
        for (int j = 0; j < 4; j++)
            weight[j] = br.readHalfFloat();
        for (int j = 0; j < 4; j++)
            linkedBone[j] = br.ReadUInt16();

        try
        {
            int numIndex = Array.IndexOf(weight, 0);
            weight = weight.Where((val, idx) => idx != numIndex).ToArray();
        }

        linkedBone.RemoveRange(weight.Count, linkedBone.Count - weight.Count);
        if (weight.Lenght != linkedBone.Lenght)
            Console.WriteLine($"Error. NoeVertWeight mismatch. {linkedBone.Lenght}  {weight.Lenght}"); //need Exception

        for (int i = 0; i < linkedBone.Count; i++)
        {
            linkedBone[i] = boneMap[linkedBone[i]] - 1;// Globlize bone Index
        }

        weightList[i].weight0 = weight[0];
        weightList[i].weight1 = weight[1];
        weightList[i].weight2 = weight[2];
        weightList[i].weight3 = weight[3];

        weightList[i].boneIndex0 = linkedBone[0];
        weightList[i].boneIndex1 = linkedBone[1];
        weightList[i].boneIndex2 = linkedBone[2];
        weightList[i].boneIndex3 = linkedBone[3];

        weightList[i].boneIndex3 = linkedBone[3];
    }

    meshs[meshs.Count - 1].boneWeights = weightList;
}
Its done now. Its not more a problem. But thank you again! Sorry i should say you earlier.


I have a new question

Code: Select all

  if indexList[index].typeID % 0x10000 == 0x0002:
what means % 0x10000 == 0x0002 ?
if(indexList[index].typeID ????)

for exemple indexList[index].typeID == 0x02010008: = if ( indexList[index].typeID == 0x02010008) that is OK
but " % 0x10000 == 0x0002 " what is that ?
