Tutorial 08 Startup

function startup() {
	canvas = document.getElementById("canvas");
	canvas = WebGLDebugUtils.makeLostContextSimulatingCanvas(canvas);
	canvas.addEventListener('webglcontextlost', handleContextLost, false);
	canvas.addEventListener('webglcontextrestored', handleContextRestored, false);

	window.addEventListener('mousedown', function() {
		canvas.loseContext();
	});

	gl = createGLContext(canvas);
	console.log(gl);
	
	setupShaders();
	setupBuffers();
	setupTextures();  
	gl.clearColor(0.0, 0.0, 0.0, 1.0);
	gl.enable(gl.DEPTH_TEST);

	draw();
}

Tutorial 09 Startup

function startup() {
	canvas = document.getElementById("canvas");
	canvas = WebGLDebugUtils.makeLostContextSimulatingCanvas(canvas);
	canvas.addEventListener('webglcontextlost', handleContextLost, false);
	canvas.addEventListener('webglcontextrestored', handleContextRestored, false);
	document.addEventListener('keydown', handleKeyDown, false);
	document.addEventListener('keyup', handleKeyUp, false);
	canvas.addEventListener('mousemove', mymousemove, false);
	canvas.addEventListener('mousedown', mymousedown, false);
	canvas.addEventListener('mouseup', mymouseup, false);
	canvas.addEventListener('mousewheel', wheelHandler, false);
	canvas.addEventListener('DOMMouseScroll', wheelHandler, false);

	gl = createGLContext(canvas);
	console.log(gl);
 
	init();
 
	pwgl.fpsCounter = document.getElementById("fps");
 
	// Draw the complete scene  
	draw();
}

sidenote, but i've found console.logging lags my machine like crazy (if you're logging in the draw loop that is)

Yeah, startup looks good. The problem I had was that it was drawing fine, but the box that's supposed to be on top of the table was way off (like 1000 off), so couldn't see it.
