Right handed system to left

Recommended Posts

Hi ! I've exported a mesh from max 5.1 to direct3d. Max has right handed system. My question how to transform vertices and local trans matrices to left handed system ? I'd be glad for any help.

If you use column-vectors and 3dsmax use row-vectors, or the other way around, then you have to transpose the matrices you get from 3dsmax.

Remember

if you use row-vectors:

[a, b, c
[1, 1, 1] d, e, f == [a+d+g, b+e+h, c+f+i]
g, h, i]


and for column-vectors:

[a, b, c [1
d, e, f * 1 == [a+b+c, d+e+f, g+h+i]
g, h, i] 1]

4x3 probably means that you have the position in the last row, correct? In that case, it is a row matrix.
And if you use the same type of matrices you don't have to transpose them
