Welcome back to another Sunday! Let's polish up the https://hex.pm/packages/matrix_gleam library for a new release. Join me at 1:30PM CDT:
-
I'm back! Today let's finish up our Beziér editor demo and figure out what to do next with #Splines. Join me at 1:30PM CDT:
-
Going live in about 15 minutes with more splines! Today we'll build some demos showcasing how to use Beziér, Catmull-Rom, and Basis splines. Join me at 1:30PM CDT:
-
Welcome to March! In today's stream, we're going to extend our parametric curves into uniform splines that conjoin multiple curves. Come join me at 1:30PM CST:
-
Thanks for attending! We were able to accurately reformulate our existing cubic splines in matrix forms and implement B-splines in less than 10 minutes. 💪
See you next week for more matrices and splines shenanigans:

Happy Sunday! Today we're going to use matrices to refine our implementation of splines and maybe make a new one. Join me at 1:30PM CST:

Added spline-to-spline mesh deformation. 🌶 Vertices mapped by distance to splines & their pose + twist. Useful for other procedural generation like tree branches, flowers, plants ☘️🌴🌲🪴🌳 etc. And it's really fun ^^

Animated versions... (only tweening uniform displacement value)

Added a new[1] configurable curve subdivision kernel for https://thi.ng/geom to (iteratively) subdivide polygons/polylines with displacement, allowing for super compact code, infinite variation, and beautiful results like shown...
[1] Actually been using this approach since 2010, initially for 3D mesh subdivisions (3rd image)

To convert a freehand drawing to a composite spline, the first step is grouping the input (a list of data points) into segments. This can be done with a corner detecting algorithm. Each segment is then approximated by a spline, e.g. a cubic Bézier.
In this demo you can see a crude implementation of the Masood and Sarfraz algorithm. A "y" glyph is traced with a graphics tablet pen, and detected corner points are shown in red.
