Detect cubic hermite spline intersection
WebMay 25, 2024 · When scaling an image with Bicubic Interpolation, the Cubic Hermite spline interpolation is used. smoothstep is one of the four basis/blend functions of this kind of interpolation. $$ f(x) = 3x^2 - 2x^3 $$ I've seen a trick used in quite a few places in Computer Graphics. Say something is interpolated linearly http://cs.uky.edu/~cheng/PUBL/Paper-Geometric-Hermite.pdf

WebOct 1, 2024 · Following the same approach, C 1 quadratic and C 2 cubic many knot spline interpolation with sharp parameters is studied in [6], and C 1 cubic Hermite splines with minimal derivative oscillation ... WebCatmull-Rom Spline (Motivation) With Bezier, we avoided specifying tangent vectors but now the curve passes through only half the points. (Essentially, we are still specifying tangents.) We would like to interpolate ALL points (unlike Bezier !) but also have the nice Hermite property of continuous tangent vector at knots.
WebSep 25, 2024 · I know the exact derivatives m k and m k + 1. I need to calculate also the speed, so I use the derivative of h 00, h 10, h 01, h 11: h 00 ′ = ( x − 1) ⋅ 6 x. h 10 ′ = 6 x − 6 x 2. h 01 ′ = 3 x 2 − 4 x + 1. h 11 ′ = 3 x 2 − 2 x. but it seems that I don’t know how to combine them to obtain the correct solution.
