Move on Objective-C, CS5 to generate Canvas and JS

Category: Adobe, Canvas

We have been reminded of MAX showing Flash CS5 generating basic HTML5 code (Canvas/JS). That’s right. Adobe is a tools company. Although it helps to own the platform (hence keeping Flash alive and wanting it to win) as the competition to build the best tools is a given, that doesn’t mean that they can’t compete Read the rest…

Touching Cloth; Canvas Fu

Category: Canvas

Andrew Hoyer shows his canvas Fu with Cloth, a great experiment using nice physics. What makes this simulation special is the speed at which everything is computed. Javascript (the language this is written in) is not exactly the most efficient language for this type of computation. This being said, much time was spent squeezing out Read the rest…

Pseudo 3D tricks from old computer games for all your Canvas needs

Category: Canvas, Fun, Games, JavaScript

It is quite interesting to see how technology moves in circles. With canvas being the new fun toy to play with for creating browser-based games we have to find solutions to fake a 3D environment to be really fast (sure there is Canvas 3D but it is overkill for most games). The trick is to Read the rest…

Canvas Benchmark

Category: Browsers, Canvas, Performance

The crew has benchmarked a path in their canvas game. It is one data point, and tests more than just Canvas itself because a lot of code is running in the game. Thus, it ends up testing the union of a particular JavaScript path and the rendering of the canvas. Here are the results: Read the rest…
