poopoodice Posted November 25, 2021 Posted November 25, 2021 Hi, I think this may be a little bit more related to math but I can't seem to find the solution. 1 stack.translate(1F, 2F, 3F); stack.rotate(Vector3f.XP.rotationDegrees(180)); stack.scale(2.0F, 3.0F, 4.0F); stack.rotate(Vector3f.ZP.rotationDegrees(x1)); 2 stack.translate(1F, 2F, 3F); stack.rotate(Vector3f.XP.rotationDegrees(180)); stack.rotate(Vector3f.ZP.rotationDegrees(x2)); stack.scale(2.0F, 3.0F, 4.0F); Is it possible, given x1 and calculate the value of x2? Thanks. Quote
Draco18s Posted November 25, 2021 Posted November 25, 2021 (edited) No, for two reasons: 1) x1 and x2 are not equal and have no apparent relationship 2) matrix transformations are non-associative The only thing I can think of is working backwards from the output of the first chunk, removing the rotation, removing the scale, then adding the new rotation and scale back.
