Shaderific 3.1 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. The update adds a new stereoscopy mode that allows to render any shader as anaglyph red-cyan 3D images. This provides a completely new 3D experience when using glasses with the appropriate red-cyan filters. Furthermore, multiple instances of the same object can now be rendered with a single shader using the new draw instanced functionality.
