That said, I’m not here to bang on about all that, I’m here to talk about Blender, my recent fascination with it, and some things I’m finding exciting about interfacing it with my work.

I also collaborate with stop-frame animator/filmmaker Ainslie Henderson, making lots of different works for tv, web, game & theatre projects. These include BAFTA-winning shorts ‘ The Making of Longbird’, ‘ Have Heart’, and more recently ‘ Betty’. I’ve been making character-driven animated films for a solid 10 years professionally now. Most solutions for drawing smooth curves are for the canvas, which is very different from 3d geometry.I’m Will Anderson, a Scottish animator & filmmaker. What would be the best approach to 'stabilize' mouse events, given an array of points? I googled left and right but did not find a good answer.

So, I thought that instead of manipulating the output (the line) I could manipulate the input (the points) and stabilise them before drawing. I tried simplifying the line with simplify.js and while close to the desired result it produces inconsistent results.I tried generating curves from some or all of the coordinates and re-rendering the line on touchend but I do not like the effect and controlling the quality of the output is very difficult.I tried many things, but nothing satisfied me yet. But once you switch to Apple pencil… this is what I tend to get 👇🏻 the lines are mostly 'jagged' If you try it with a mouse, the result are pretty okay. unproject the coordinates based on the camera The only thing I'm doing here is this: //convert coordinate to three.js space

Here's a jsfiddle that shows the functionality. The application works in any browser but I'm struggling with my main target platform: the iPad with the Apple pencil.Ĭompared to a mouse, the Apple pencil fires a very high amount of touchmove events and that causes my lines to be 'jagged' in some scenarios, especially when the line is drawn slowly. I'm working on a small application that allows users to draw freehand in 3d with three.js (the result is somewhat similar to Blender's grease pencil).
