mediump vs highp precision on Embedded GPUs

There are a lot of  tests on GPU performance, in terms of how many operations per sec (rendering, float arithmetic, etc..), but not a lot on quality and precision. Most would argue that such a benchmark is not very relevant, well that is true in general cases but not all (actually its like having 5k [...]

GPU based Resolution Independent Font & Curve Rendering – initial Release

Below is about the latest project done by Sven Gothel and myself, which is now published/merged in JogAmp – Jogl Project. The story: At first we started this project as an idea, started with a chat with Sven on possible ways to by pass the Microsoft patent on GPU Curve Rendering. So after digging into [...]

GPU Resolution Independent Curve Rendering – Brief

In the past couple of weeks, I worked on developing a new technique to create an API for resolution independent curve bounded regions and text in general.  The main goal of this project was to move out of the Microsoft Patent Loop/Blinn approach which uses Bezier (Quadratic/Cubic) curve rendering to solve the problem. To by-pass the [...]
