Hi,

Some years ago Daniel Piker showed an example how to interpolate transformations matrices for fabrication layouts. Is that example still present somewhere or something similar? I tried to search gh forum without luck

Hello,

you need to convert from matrix(3x3) to quaternion, then use a āslerpā function, to interpolate between two quaternions

and then convert back to matrix(3x3) again. This is just for rotation. For location simple use loc+(deltavector * t )

conversions can be found here:

be aware that quaternions can be x,y,z,w or w,x,y,z, order. Do you know how get from a rotationmatrix(3x3) to a transformationmatrix(4x4)?
