This page contains random tips and code snippets that Verge3D devs or Verge3D DevKit users may find useful for their work.

Getting v3d namespace from iframe

document.getElementsByTagName("iframe")[0].contentWindow.v3d

e.g. to print performance profile from the iframe:

document.getElementsByTagName("iframe")[0].contentWindow.v3d.apps[0].printPerformanceInfo()

or to enable FPS counter:

document.getElementsByTagName("iframe")[0].contentWindow.v3d.apps[0].showFPS()

Debugging Verge3D render target

Use the following code to create a plane with the output of the given render target:

// DONT FORGET TO REMOVE IT!
var texture = renderTarget.texture
var geometry = new v3d.PlaneBufferGeometry(3, 3);
var material = new v3d.MeshBasicMaterial();
material.map = texture;
var planeMesh = new v3d.Mesh(geometry, material);
planeMesh.position.x = 6;
v3d.apps[0].scene.add(planeMesh);

Code Indentation Style

The K&R style, 4 spaces:

function someFun() {
    const someConst = 10;
    const alwaysTrue = true;

    for (let i = 0; i < someConst; i++) {
        if (alwaysTrue) {
            console.log(`Hello ${i}!`);
        }
    }
}

Key Triplets

There are several key triplets supported by Verge3D which are useful for debugging. To execute a triplet, wait until a Verge3D app finishes its loading, then press the same key thrice very quickly.

  • PPP — print performance profile. See here for more info.
  • FFF — show/hide FPS counter in the upper left corner of the rendered canvas.
  • HHH — halt/continue application rendering.

Short Links

These short links can be very helpful for debugging mobile devices.
