Interpolate transformation matrix
WebNotes on rotations To transform more than a single vector the preferred representations are rotation matrices, while for other usages Quaternion is the representation of choice as they are compact, fast and stable. Finally Rotation2D and AngleAxis are mainly convenient types to create other rotation objects.. Notes on Translation and Scaling Like AngleAxis, these … WebIn mathematics, bilinear interpolation is a method for interpolating functions of two variables (e.g., x and y) using repeated linear interpolation.It is usually applied to …

The same as above but the original maps are stored in one 2-channel matrix. Reverse conversion.
WebThe affine transformation has an important property that two successive affine transformations combine also into an affine transformation. If 2D points are represented in vectorial form, then the affine transformation consists of multiplication by a 2×2 matrix followed by addition of a vector; more convenient homogeneous coordinates …

The function generates a trajectory that starts at the initial orientation, r0, and goes to the final orientation, rF. r0 and rF must be of the same type. For example, if r0 is a scalar so3 object, then rF must be a scalar so3 object.
