8bit good for lighting and such - 32bit view for pixel copy?

[Sarah-C]

This may speed it up a little?

let ctx = c.getContext("2d");
let canvasDataWrapper = ctx.getImageData(0, 0, c.width, c.height);
let canvasData = imageDataWrapper.data; // 8 bit ARGB
let canvasData32 = new Uint32Array(canvasData.buffer); // 32 bit pixel

copyFnc = function(idxC, idxT){
canvasData[idxC + 0] = textureData[idxT + 0];
canvasData[idxC + 1] = textureData[idxT + 1];
canvasData[idxC + 2] = textureData[idxT + 2];
canvasData[idxC + 3] = 255;
};

Vs

copyFnc = function(idxC, idxT){
canvasData32[idxC] = textureData32[idxT]
};

Hi thanks for your interest and taking the time to post this. I might not have time to look at this for a couple of months but I've always been curious as to whether this could be speeded up so I'm sure I'll look at it at some point.

I'm a firm believer of "relaxation driven development." That's where you're relaxed and decide to do a little bit of a puzzle/code for fun. Not that much around these days! Catch up with you in a month or two!
