What is rotation interpolation?
This is sometimes called three-axis interpolation. The orientation path can also be interpolated along an axis of rotation, with a constant rotation speed. This is sometimes an interpolation of an axis or a SLERP, this can be calculated geometrically or using quaternions.

How is the formula interpolated?
Know the formula of the linear interpolation process. The formula is y = y1 + ((x – x1) / (x2 – x1)) * (y2 – y1), where x is the known value, y is the unknown value, x1 and y1 are the coordinates below the known value of x, and x2 and y2 are the coordinates that are above the value of x.
How is Slerp calculated?
More familiar than Slerp’s general formula is the case when the final vectors are perpendicular, in which case the formula is p0 cos θ + p1 sin θ. Letting θ = t π/2, and applying the trigonometric identity cos θ = sin (π/2 − θ), this becomes Slerp’s formula.
What does the Slerp quaternion do?
Quaternion. Slerp allows you to interpolate between two rotation values. The third parameter of this function is a percentage value: basically, how far along the path between “Rotation A” and “Rotation B” you want the returned rotation to be. If you use Quaternion.
Can you interpolate in Excel?
Many people want to interpolate data that they have digitized with Dagra into Microsoft Excel. Unfortunately, Excel doesn’t provide an interpolation function, but there is a simple approach.
How to calculate the number of rotation interpolations?
This is where the function of wrapping your formula counterclockwise in a MOD() function comes in: Combining all the elements from Parts 1-4 together, the answer is: N = The number of interpolations you want to do (eg 2 is half, 3 is in thirds, etc.) My preferred way of dealing with angle is to use units that are a power of 2 per revolution.
How to interpolate between rotation matrices, stack?
Edit: This is the formula almost everyone quotes, it’s from a SIGGRAPH article from 1985. – qm = interpolated quaternion – qa = quaternion a (first interpolated quaternion between) – qb = quaternion b (second interpolated quaternion between) – t = a scalar between 0.0 (in qa) and 1.0 (in qb) – θ is half the angle between qa and qb
What is the best way to interpolate an angle?
My preferred way of dealing with angle is to use units that are a power of 2 per revolution. For example, if you use 16-bit signed integers to represent -180 to +180 degrees, you can simply take (from-to)/num_steps to do your interpolation.
What is the correct way to interpolate y 1 and y 2?
Substituting the values of x, x 1, and x /2 in their places gives (37 – 30)/ (40 -30), which reduces to 7/10 or 0.7. Substituting the values for y 1 and y 2 at the end of the equation gives (5 – 3) or 2.
