SHADOW QUICK MENU FULL
As the canvas element is pixel-based, any content change usually requires a full redraw of all chart components, each being re-described and/or re-generated in your own Javascript code. Thus, for the kinds of animated 2D charts I need, SVG seems to have much more optimisation potential than using a HTML5 canvas element. The actual rendering of that cached element is then done by a much faster lower-level process (OpenGL/GPU and the SVG engine respectively). Any complex calculations in Javascript need only be done once to build up each visual component, or to rebuild if it physically changes.
The core ideas when working in both are actually pretty similar - building up a set of visual components that are cached and rendered separately (OpenGL vertex buffer objects and SVG elements respectively). The marriage of WebGL for 3D visualisation and SVG for 2D data presentation also turns out to be a pretty happy one. Sure this was on an i7 processor, but it meant that the core technologies were not going to be the kind of bottleneck that I thought they’d be.Īs it turned out, there was scope for some pretty fundamental optimisations, so now it’s even quick enough on an iPad as well as most of my old Android tablets.
I’m actually quite stunned as, even before any optimisation whatsoever, I found that I could build and rebuild the entire Sun-path mesh on every change in pretty well real time. This started out as an experiment to see just how responsive I could make the generation and display of 3D Sun-path diagrams and shadow projections using JavaScript and WebGL. You can set the location using the map by either dragging the locator icon around or clicking in the position you want. You can also use both the popover buttons and information panels located in the top-right to set the date, time and location.
SHADOW QUICK MENU UPDATE
It should be fast enough to update in pretty close to real-time as you drag the locator within the map or the date/time in the day-length chart. The aim was to clearly illustrate the relationship between geographic location and the annual Sun-path. The SVG chart defaults to showing the annual variation in day-length, but you can also select an analemma chart or several different types of 2D Sun-path diagram.
SHADOW QUICK MENU GENERATOR
Try out a new shortcut and watch the panel update.This app connects an interactive Google World Map to a 3D Sun-path diagram, shadow map generator and a 2D SVG chart displaying a range of solar information. You can continue to use in Figma while viewing the keyboard shortcuts panel. To view your current keyboard layout or select another one, select the Layout tab. Use the tabs at the top of the panel to explore shortcuts related to each set of actions. Click in the bottom-right and select Keyboard shortcutsįigma will open the shortcuts panel along the bottom of your screen.There are two ways to open the shortcuts panel: You can see which shortcuts you've already used, or discover new ways to speed up your workflow. Open the keyboard shortcuts panel to view a selection of shortcuts. You have access to a range of keyboard shortcuts in Figma design and FigJam files. For example: a shortcut to open your password manager. This is something to consider if you have applications with conflicting shortcuts. Note: It's currently not possible to create custom keyboard shortcuts or quick actions.
