This is a THREEjs Virtual Tours Engine that uses scene.background to switch equirectangular image by fading out the THREEjs render canvas to white so that loading of the next image is not seen, when the texture loader THREE.TextureLoader() completes the THREEjs render canvas is then fade in to show the scene rendering.
This project uses orbit control THREE.OrbitControls to look around and animated gif textured on a plane geometry mesh to move from location to the next.
THREEjs Virtual Tours using 360 photos, the images are 4k and photoshoped to doubled the size to 8k.
Anyone can create your account and upload your 360 photos here, to create the tours you need to specify the camera positions and orientation, the size of the marker.
You need to make the transition seamless and instant to have appeal. Those white whole-screen-flashes and lags are annoying.
In the first case (real life env) pre-loading a bunch of nearby hotspots at lower-res to make the transition instant, and load the high-res version after the user has clicked to one spot would be a better user-experience.
In the second case (virtual env), you don’t need 360 textures, you can run it in 3D if you optimize enough the code eg using instances, etc.
