Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Orbit controls for A-Frame.

Automatically toggles look-controls on and off when entering and exiting VR.

Great for using as a viewer, better and easier than using WASD + mouse-drag, or being stuck in the same position on mobile.

The other A-Frame orbit controls components were weird since they fully ported the THREE.OrbitControls logic into a component. This component just straight up uses THREE.OrbitControls in a clean and performant way.

API

Same API as THREE.OrbitControls, supports all the properties.

| Property | Description | Default Value | | -------- | ----------- | ------------- | | autoRotate | Set to true to automatically rotate around the target. | false | | autoRotateSpeed | How fast to rotate around the target. | 2 (30 seconds per rotation at 60fps) | | cursor | The focus point of the minTargetRadius and maxTargetRadius limits. It can be updated manually at any point to change the center of interest for the target. | 0 0 0 | | dampingFactor | Damping inertia if enableDamping. | 0.1 | | enabled | Whether enabled. You can also call .pause() on the entity. | true | | enableDamping | Set to true to enable damping (inertia), which can be used to give a sense of weight to the controls. | true | | enablePan | Enable panning (i.e., right click drag or three finger drag). | true | | enableRotate | Enable rotation (i.e., left click drag or single finger drag). Use Azimuth angles to constrain to single axis. | true | | enableZoom | Enable zoom (i.e., scroll or pinch). | true | | initialPosition | Initial position of the camera. Set this rather than position. | 0 0 0 | | keyPanSpeed | How fast to pan the camera when the keyboard is used. Default is 7.0 pixels per keypress. | 7 (pixels per keypress) | | minAzimuthAngle | How far you can orbit horizontally, lower limit. From -180 to 180 degrees. | Infinity (no limit) | | maxAzimuthAngle | How far you can orbit horizontally, upper limit. From -180 to 180 degrees. | Infinity (no limit) | | maxDistance | How far you can dolly out. | Infinity | | maxPolarAngle | How far you can orbit vertically, upper limit. Range is 0 to 180 degrees. | 90 | | minDistance | How far you can dolly in. | 0 | | minPolarAngle | How far you can orbit vertically, lower limit. Range is 0 to 180 degrees. | 0 | | minTargetRadius | How close you can get the target to the 3D cursor. | 0 | | maxTargetRadius | How far you can move the target from the 3D cursor. | Infinity (no limit) | | minZoom | How far you can zoom in (OrthographicCamera only). | 0 | | maxZoom | How far you can zoom out (OrthographicCamera only). | Infinity (no limit) | | panSpeed | Speed of panning. | 1 | | rotateSpeed | Speed of rotation. | 1 | | screenSpacePanning | Defines how the camera's position is translated when panning. If true, the camera pans in screen space. Otherwise, the camera pans in the plane orthogonal to the camera's up direction. | false | | target | Focus point of controls. look-at vector. | 0 0 0 | | zoomSpeed | Speed of zooming / dollying. | 1 | | zoomToCursor | Setting this property to true allows to zoom to the cursor's position. | false |
