   3DS reader and Chunk 0x4160
  Hi All,I am writing a 3DS reader and from one month I am stuck on Chunk 0x4160.I tryed all the possible combinations and all the code examples found on the internet but nothing worked.Does anybody know exaclty how to handle the 4x3 matrix of the 0x4160 Chunk?Don't send me another link to a website page because I have already checked them all.I want the truth, nothing but the exact operations list to use this matrix on the object vertices to obtain the correct positioning in 3D space.Thanks so much,Alberto   
  Mmmm, let me try and let you know...Do you remeber if I need to invert the matrix before multiplying each vertex by it?Thanks a lot,Alberto   ;  I just deleted my post because I noticed that you wanted the operations and not the content of the chunk, so I thought my answer was irrelevant. But yes, the point is that to get the object vertices into world space, you need to multiply them by the inverse of the matrix.
