I want to rotate a float3 -90 degrees. i.e from (0,1,0) to (1,0,0). I tried to multiply the float3 with quaternion.AngleAxis but that doens't work. If anyone knows how to do this without manually calculating the matrices pls help..
how would I do it in code tho? like I said multiplying quaternion with float 3 doesnt work so....? Thanks
I suggest look into topics covering adding and subtracting rotations, using quaternions. In Dots you of course need use math.mul, instead * Order of multiplication is extremely important, when comes to deal with rotations.
Nvm, I just use matrix calculation. For anyone wondering if you wanna rotate float3 to the z-axis just use this formula/code : float3 vector float3 rotatedVector = new float(vector.y, -vector.x, vector.z) basically you just switch the y and x and multiply x with -1
You can multiply it by cos/sin of target angle. For example: Code (CSharp): float angle = -90; float x = 1; float y = 0; float z = 0; float3 newVector = new float3( x * math.sin(math.radians(angle)), y * math.cos(math.radians(angle)), z );
