Additional to my recent question concerning multiple 3d sections on a page:
Researching this topic I stumbled across this great project by active theory:
As it seems they use a single canvas with several frame buffers for the sections. Although this solution is not really possible for my project I was curios how such a setup could look like. I assume this is beyond the layer of play canvas and needs some heavy shader / core webgl magic? ( Rendering multiple cameras within one PlayCanvas Scene to Framebuffers and then stacking them) How do those wizards keep interaction working?
Digging into the code, it does look like a multiple camera, single app with shaders approach.
At a guess, they are moving all cameras at the same time when you scroll and the shader is used for the wavey line effect. Probably can use the viewport property to control how much of the screen each camera renders.
Tempted to give this a go when I get some time. It’s a cool effect.
that makes sense. But wouldn’t such a technique mess up the additional click / touch interactions? They have some simple object drag manipulation going. Sorry if that’s a no-brainer, but I’m fairly a noob when it comes to shader manipulation.
