I read about how to switch to canvasrenderer if webgl is not supported.
renderer = Detector.webgl? new THREE.WebGLRenderer(): new THREE.CanvasRenderer();
I'm not sure how to completely remove everything if webgl is not detected. I have an image in the background that I would prefer to show instead of leaving the empty div where my three.js script is.
Here is the link to the script on jsfiddle: https://jsfiddle.net/nballiett/kkxo8kc5/3/
Sorry if this is an easy question, I'm still learning.
To determine if webGL is supported, utilize the Detector function, then proceed to execute the init() function if supported. Otherwise, execute an alternative JavaScript code:
if ( Detector.webgl ) {
init();
animate();
} else {
// webGL not supported
// perform alternate action
}
Check out the updated jsfiddle here: https://jsfiddle.net/kkxo8kc5/4/
