gl-css3d

Synchronize CSS 3D transformations to a WebGL scene

Usage:

var createCSS3D = require('gl-css3d');

// pass an HTML DOM element node, such as an <iframe>
var css3d = createCSS3D(htmlElement, opts);

// assuming you are using stackgl gl-now/game-shell:

// in the gl-init callback:
css3d.ginit(gl)

// in the gl-resize callback:
css3d.updatePerspective(cameraFOVradians, shell_width, shell_height);

// in the gl-render callback:
css3d.render(view, proj);

For an example embedding an iframe run npm start, or try the live demo. The iframe accepts pointer events and can be interacted with as an ordinary webpage. Click the button to toggle mouse inputs to control the camera instead (drag to move, scroll to zoom; uses game-shell-orbit-camera).

Options

• planeWidth (2), planeHeight (2): size of the plane in world units

• tint ([0,0,0,0]): color to draw the WebGL object in front of the CSS3D element, defaults to fully transparent

• blend (false): whether to enable blending, defaults to false so tint is not influenced by the colors of the WebGL scene behind it

• flipX (true), flipY (true): whether to invert the X and Y axes from WebGL to CSS3D

• backface (true): whether to include two extra triangles in the WebGL mesh for the rear side of the plane
