In the previous article we performed some simple optimisations which enormously improved the frame rate of our animations. However, we mentioned that increasing the size of the area that we wish to blur will slow the frame rate because the complexity of the blur operation will increase exponentially. In this article we’ll look at an alternative approach which should permit us to animate larger areas.

Blurring Images – Part 6

Friday, March 21st, 2014

In the previous article we looked at frame rates, and explored how we can measure them by adding some simple benchmarking logging. In this article we’ll look at implementing our dynamic blurring so that we can animate things, and optimising things to improve our framerate.

Recently there was a comment on the article on Text Shadows asking how to fill text with a gradient. In this article we’ll look at a simple technique for doing precisely that.
