Hi Saad,
So, we take the direction of the previous step and the newly sampled direction. Then we look at corresponding vectors that have the same point of origin ; one points in the old direction, the other points in the sampled direction. Is it the cosine of the angle between those direction vectors that we're controlling with the curvature threshold? And is it that cosine value that is bounded between 0 and 1?
Cheers,
Jackson
