    We are having a GPU consumption problem the seems to come from the fact that the scene is continuously rendered even if the scene is still, which would leave users using integrated gpus at 100% usage. Is there any way to make the scene still(like a snapshot) until the user either changes something or manipulates the view?

    Among the code examples there is this one, which acts exactly how we would like it to, it uses the gpu only when being manipulated, then it goes to 0%, as if it would show a still image.

    https://cdn.soft8soft.com/demo/examples/index.html#webgl_clipping_intersection

    Also, we get notices in the console of this kind, can this be affecting performance as well?:

    v3d.WebGLProgram: gl.getProgramInfoLog() C:\fakepath(122,25-100): warning X3571: pow(f, e) will not work for negative f, use abs(f) or conditionally handle negative values if you expect them

    Thank you!

    Hi,

    You can possibly override the default animate() method of the App class, which looks as follows

    animate: function() {
    var scope = this;

    var cb = function() {

    var elapsed = scope.clock.getDelta();
    scope.elapsed = elapsed;

    if (scope.mixer)
    scope.mixer.update(elapsed);

    if (scope.controls)
    scope.controls.update(elapsed);

    var rbs = scope.renderCallbacks;
    for (var i = 0; i < rbs.length; i++) rbs[i](elapsed, scope.clock.elapsedTime); scope.render(); scope.frame++; } scope.renderer.setAnimationLoop(cb); } to only run when you need it. We are aware of that WebGL warning on Window but I don't think it is a major cause. The integrated GPUs do not allow for highly parallel computing.

    Hi,

    Thanks you for the fast reply, is this code altering in the v3d.js file ?
    Could you provide us with the altered file that runs the render on manipulating or changing prefs? Thank you!

    Hi,

    As we started working on the implementation of the dispose method for cleaning up GPU resources, I suggest we wait until its ready and first see how it works for your project. Then we can try the approach with skipping the rendering frames.

    Hi Yuri,

    Wouldn’t this be a great feature for Verge3D in general? Seems like a super feature to me.

    I understand your comment with regards to the dispose method. But in 10 days time we will have a lot of clients going live with our product and they will not be happy if their machines grind to a halt when using our application…

    Yes, but it can only work in the specific case when a scene is updated via user input.

    I understand. We can consider implementing this then. I’ll drop you a line.

    Hey Yuri,

    How can i access setAnimationLoop function, i don’t have it on renderer object.

    It seams that is not supported by Three.js version which is bundled in v3d.js file, at least one we use.

    Hi,

    How do you access the setAnimationLoop function?

    On a side note Yuri: can you share how your team implemented it on https://cdn.soft8soft.com/demo/examples/index.html#webgl_clipping_intersection ?
    Because there it seems to be already working.

    I would also like to add a vote for this as a feature. Would be great for applications where the user don’t constantly move around and interact, for instance when the application is just a small part of a page, like a product preview where there is a loot of other information to read and look at on the page.

    I tried with this:

    scope.renderer.setAnimationLoop(cb);

    but setAnimationLoop does not exists in my renderer object
