I'm buying it tonight! I hope it's good for semi-beginners. I've got a grasp on Javascript, HTML, and CSS, but that's about it. It looks awesome!

Great! I hope you will like it. I'm sure you'll be fine. Leave an Amazon review if you enjoy the book!

I have uploaded your example to my android phone and it does not work. Bought your book on amazon but having a hard time reading it when I can't get your example code to work. Also does not work on android emulator. Would be interested in any ideas.

Seems I may have to get phone gap implemented. Sorry. Great book. I'll figure it out. I'm a newbie.

I just bought the book on Amazon. I've been developing websites using JS and HTML5 and would like to see what else these browsers can do! :-)

@Chad: Sweet, hope you will enjoy it.

@wvmack: Either put the files on a web server and access them with the mobile browser or experiment with something like Phonegap.

Please be aware that Amazon (US) has the ENTIRE book available for preview on their buy page...you might want to let them know.

@robw963: thanks for the heads up!

Hi Jacob,
Interesting book. Is there an errata page for this book? I notice a couple of things wrong in the book so i wanted to know if they have been reported?

To give u one, on page 213 of the digital edition, you say that the dot product and the multiplication are same. This is wrong. The multiplication operator multiplies each element with the corresponding element of the other vector. The dot product function however multiplies and then sums all of the products to return a scalar. So the given example should be
vec2 v0 = vec2(3.5, 4.0);
vec2 v1 = vec2(2.0, 0.5);
float v0Dotv1 = dot(v0,v1); //returns 9
and if you assign this to a vec2 the result would be
vec2 v2 = dot(v0, v1); //returns vec2(9,9)

Just updating you on this error.

Hmm, I can't find an errata page, actually. I'll have to look into that. Thanks for the heads up!
