Last time we created a simple iPhone application that made a ball bounce around the screen. This time we are going to extend the last example to use the accelerometer to create a gravity influence on the ball. So as you tilt the device the ball will roll in the direction of the tilt. The [...]

Exploring iPhone Graphics Part 2
April 25th, 2008 
Richard In Part 1 of this series of articles we drew some simple graphic primitives on the iPhone display. In this article we are going to look at how to do some simple animation. The goal of this example is to create a 2D ball that bounces around the iPhone screen. First of all we need [...]
Plotting a Sine Wave with the iPhone SDK
April 17th, 2008 Richard Got the following request from Leo on the Exploring iPhone Graphics Part 1 article: Could you give me a quick primer on how to draw a sinus curve (or similar curve) with the data coming from an array? Here it is: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 [...]

In later articles I plan to get into animation, using the accelerometers and maybe even a little OpenGL. The sample application for this article is [...]
