[SOLVED] reading indeces from D3DXMESH
Author
Hi!
I'm trying to get the Indeces from a D3DXMESH, but i cannot figure out how?
I have tried to solve it on my own, but I realised I couldn't.
As far as I came:
Typically an index buffer will have 16-bit indices, in which case you should use an unsigned short* pointer instead of a BYTE* pointer. You can check for sure by calling GetDesc on the index buffer and checking the Format member of the D3DINDEXBUFFER_DESC.
i have a working solution i think , checks for the format 16 or 32 bit and gets the x,y,z in to a D3DXVECTOR3, if i find it i will post it

thank you, that helped a lot, but ive got another problem now:
i have tried something that writes the indices into a textfile. and i have changed pIndeces from BYTE* to unsigned short*.
ive looked into the .x file and the indices are:
0,3,2,1, 4,7,6,5, 8,11,10,9, 12, ...
but when i print them, i get (i have sorted/formatted it):
0,3,2,0,2,1,
4,7,6,4,6,5,
...
my question:
what am i doing wrong?
thank you

ofstream myfile;myfile.open ("test.txt");for (UINT j = 0; j < noOfIndices; ++j) { const unsigned short* d = (const unsigned short*)pIndexes; myfile << *d << "\n"; pIndexes++;}myfile << "end" << "\n";myfile.close();ive looked into the .x file and the indices are:

i solved it, thank you for helping me =)
here's the code i use:
here's the code i use:
DWORD nFaces = mesh->GetNumFaces(); ofstream myfile; myfile.open ("process.txt"); UINT count = 0; for (UINT j = 0; j < nFaces*3; ++j) { if (count != 2 && count != 3) { const unsigned short* d = (const unsigned short*)pIndexes; myfile << *d << "\n"; } count++; if (count == 6) { count = 0; } pIndexes++; }This topic is closed to new replies.
