With
function init() {
try {
var canvas = document.getElementById("glcanvas");
gl = canvas.getContext('webgl', {preserveDrawingBuffer: true});
if ( ! gl ) {
throw "Could not create WebGL context.";
}
I cannot reproduce this.
With
function init() {
try {
var canvas = document.getElementById("glcanvas");
gl = canvas.getContext('webgl');
if ( ! gl ) {
throw "Could not create WebGL context.";
}
I can reproduce the drawing disappears effect by hitting enter on the text
field.
I haven't studied your code enough to see why you are not redrawing the
cube in draw().
Does that help?
Thanks,
