altering dimensions in three.js

My question may seem a bit silly, but it's about resolution in THREE.js. I have experience with OpenGL and some frameworks related to it, so naturally, I became interested in webGL and Three.js. After trying out some simple demos, I decided to create my own project, but I encountered a problem:

How can I achieve having a canvas with dimensions of 640x480 px, but render a 320x240px scene on it at full size?

Is this mainly for performance reasons or for achieving a more artistic/old school appearance?

Thank you in advance.

Answer №1

To resize a canvas element, you can utilize CSS. Start by setting the canvas to 320x240px using html attributes or JavaScript, then employ CSS to adjust it to 640x480px. This process will effectively scale both the canvas and its contents.

Here is an example:

<canvas id="c" width="128" height="128"></canvas>

#c {
    width: 256px;
    height: 256px;
}
