Shaderific 2.5 is now available. Shaderific is an educational app for iPad, iPhone and iPod touch that helps computer science students and experienced developers to get started with OpenGL ES 2.0 shader development. This update adds support for particle systems with spherical and cubic shape. The number of particles (particle density) can be changed in a range of 1,000 to 100,000 particles without interrupting the rendering loop. The added multitouch support provides shader programs with access to a new uniform array containing the screen coordinates of the respective touches. Furthermore, shader programs can now make use of the whole screen real estate by using full screen mode. This can be very useful to prototype image processing shaders (e.g. texture blending).
