right hand coordinate matrix to left hand coordinate?

opengl matrix blender irrlicht
VivekParamasivam picture VivekParamasivam · Dec 19, 2013 · Viewed 9k times · Source

i'm using blender for my 3D model which uses right-hand coordinate system, so when i try to import the model to my opengl engine(irrlicht, left-hand coordinate system) the mesh and animation looks inverted in x axis.

(for ex, in blender my human Model performs animations in right hand but in opengl it does it on left hand side.)

so i'm trying convert the matrices from right hand coordinate to left hand. Can any one give some guidelines to proceed ?

edit: i'm trying this for animated model like b3d etc.

Confusion between C++ and OpenGL matrix order (row-major vs column-major)

I'm getting thoroughly confused over matrix definitions. I have a matrix class, which holds a float[16] which I assumed is row-major, based on the following observations: float matrixA[16] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 }; float matrixB[4][4] = { { 0, 1, 2, 3 }, { 4, 5, 6, 7 }, { 8, 9, 10, 11 }, { 12, 13, 14, 15 } }; matrixA and matrixB both have the same linear layout in …
