Getting canvas/context variables about regl HOT 3 CLOSED

Ok, you can now do this in 0.6.0. There is an unsafe escape hatch which allows you to grab the webgl context as regl._gl. However a better way to get the drawing buffer height is to use the context variables. For example:

regl.frame((context) => {
  console.log(context.drawingBufferWidth, context.drawingBufferHeight)
})

from regl.

Nope! If you want a handle to the canvas/context you need to pass them to regl yourself and maintain that reference. This might change later, but at the moment I am writing this way as a challenge to try to design things so that you never have to dig down to that level.

Regarding that approach with the uniform, that is indeed the correct way to do it. The reason for this is that the size of the WebGL context might change if you resize the window.

You can also access this information from outside a dynamic variable using regl.stats.

from regl.

I see.
Well, for now it seems a bit more difficult than usual way:

draw({
size: [ctx.drawingBufferWidth, ctx.drawingBufferHeight]
});

But thanks anyways!
