Programming today exercises our symbolic reasoning. We write code—a sequence of symbols—in a text editor.

But when we explain ideas to colleagues, we don’t just speak words, we draw diagrams and gesture with our hands. We augment the symbolic channel with a spatial channel.

How can we communicate programs to a computer over a spatial channel?

Shadershop is an interface for programming GPU shaders in the mode of a direct manipulation image editor like Photoshop. It is an experiment in leveraging the programmer’s spatial reasoning the way that coding today leverages the programmer’s symbolic reasoning.

Video++ is a video and image processing library taking advantage of the C++14 standard to ease the writing of fast video and image processing applications. The idea behind Video++ performance is to generate via meta-programming the simplest code possible such that the compiler enable optimizations like loop vectorizing. Its main features are:

Generic N-dimentional image containers.
A growing set of image processing algorithms.
Zero-cost abstractions to easily write image processing algorithms for multicore SIMD CPU processors.
An embeded language to evalute image expressions.
