Different results with Matrix4x4.MultiplyPoint and Matrix4x4.rotation
Hello,
I have a GameObject GO1 representing a Camera with four spheres (s1_1, s1_2, s1_3, s1_3) as children. Then I have another GameObject GO2 with four more spheres (s2_1, s2_2, s2_3 , s2_4) as children. The GO1 and GO2 have slightly different positions and rotations. Similar, the spheres of GO1 and GO2 also slightly different distributed.
I calculate the rotation and translation matrix ( Matrix4x4) to move the spheres of GO2 (s2_1, s2_2, s2_3 , s2_4) to get as close as possible to the respective spheres of GO_1 (s1_1, s1_2, s1_3, s1_3). Then I use the Matrix4x4.MultiplyPoint with each sphere. This works fine.
However, I would like to just rotate and move GO2 and not each single sphere using the matrix that I calculated. To do so, I use Matrix4x4.rotation and I multiply it with the transform.rotation of GO2. I thought that I should get the same result but it doesn't. Does anyone have an idea on how to rotate GO2 using the rotation matrix? If I use Matrix4x4.MultiplyPoint with GO2 it just changes the position but not its rotation and thus the children are not rotated accordingly.
Thanks!
Do you mean transform.rotation = matrix.rotation ?
Performs full transformation of a vector (so scale, rotation and translation)Matrix4x4.MultiplyPoint
Extracts a rotation component from a 4x4 matrix. Returns amatrix4x4.rotation
Quaternion.
I have tried transform.rotation = matrix.rotation and transform.rotation *= matrix.rotation but both give wrong results.
I can try to help but you need to show some code here. It's hard to guess anything more from your description as it is now.
