I am using github gists, and then make a link to openjscad taht opens that gist

example:
https://jscad.xyz/#https://gist.githubusercontent.com/hrgdavor/7419194097fc2ffd42d840f82fc83ca1/raw/31e0194693629e780e3b82848f9082d1796814ec/rounded_top.js

and gist is :
https://gist.github.com/hrgdavor/7419194097fc2ffd42d840f82fc83ca1/

nice prototype

is it opensource ?

There is a nice V2 example from one of the openjscad users here:
https://github.com/sdaau/openjscad_example_selfhost_spa_webpage

maybe this is something you can use ?

@hrgdavor here is video showing how I expect rotate to work
versus how it works on xyz

I have also created a pull request. But this is not real pull request, just wanted to somehow share the code I hacked quickly to get rotation to work.

If the pull request has any potential, I welcome your input so I can make this my first code contribution

@hrgdavor I am playing with viewer.js
and was able to remove the nasty effect I dont like with rotation on V2 by setting:

controls.drag = 1;

and changed how events are throttled

    var delta = [0,0];
    var timer;
    // rotate
    gestures.drags
      .forEach((data) => {
        const ev = data.originalEvents[0]
        const shiftKey = (ev.shiftKey === true) || (ev.touches && ev.touches.length > 2)
        if (!shiftKey) {
          delta[0] -= data.delta.x;
          delta[1] -= data.delta.y;
          cancelAnimationFrame(timer);
          timer = requestAnimationFrame(doRotate);
        }
      })
    function doRotate(){
      const updated = orbitControls.rotate({ controls, camera, speed: rotateSpeed }, delta)
      delta = [0,0];
      controls = { ...controls, ...updated.controls }
    }

this way changes will acumulate if animationframe is not executed

@z3dev I think you are still missing the point. It is not the rate of refresh or amount of rotation that is the issue here. It is inertia. When I move mouse and stop moving, the rotation continues. Can you not see the difference with V1 where rotation follows the mouse and when mouse stops rotation stops imemdiatelly. In V2 it looks like some intentional elastic motion that does not match mouse position at all. If I move mouse faster it is like it gets more momentum and then takes longer to slow down and stop. it should stop the moment I stop moving my mouse ... pls, why dont u understand what I am saying

cool, but parameters are not shown:

in extension:

@z3dev changing options only makes issue more visible but does not solve it. Are you not seing there is inertia when rotate is following the mouse....

if I move my mouse few times left / right the rotation does not end in same place if mouse is i nsam place as it does in V1. .. it is so anoying I cant describe :(.

@z3dev all of that was tested on https://jscad.xyz/ ... but I will try local instance and settings

@z3dev said in V2: Feedback render sluggish on GTX1070:

@hrgdavor yup. thought that it might be 'rotate'. it feels a little sluggish at times.

not just sluggish, it seems like intentional smoothing with bounce, it feels horrible

pan as well (it is even worse, moves like 10% of mouse movement)
