I've been diving into three.js and came across an interesting example. The developer starts by creating a canvas element and then connects the renderer to that specific canvas.
<canvas id="c">
</canvas>
const renderer = new THREE.WebGLRenderer({canvas});
Next, the developer grabs the canvas element and saves it as a variable using canvas = renderer.domElement;
Can someone explain the distinction between canvas.width and canvas.clientWidth for me?
The distinction arises from the specifications of the HTMLCanvasElement (<canvas/>). The property width is unique to HTMLCanvasElement and represents the "number of logical pixels" contained within one row of the canvas. On the contrary, the property clientWidth is shared among all Elements and signifies the number of pixels horizontally taken up by the canvas. These values do not necessarily match — for instance, it is typical to draw on a canvas at a resolution different from the space it occupies on the page, either to enhance performance or to accommodate a devicePixelRatio >1, like that of a high-density screen.
