This is a repository of examples of Halide programming.

According to Halide's authors, "Halide is a new programming language designed to make it easier to write high-performance image processing code on modern machines." The examples here serve two purposes:

• To help grow our experience and skill with Halide
• To push Halide in ways its authors may not have imagined

Prerequisites:

• CMake 3.0 (or later)
• g++ 4.8+ (the main developer uses 4.9)
• SDL2
• A recent distribution of Halide

Build script:

For the first build, you must specify the path to your Halide installation:

$ ./build.sh -DHALIDE_ROOT=<path to Halide>

The example programs will be built and installed into the build-dir/bin directory.

Subsequent builds can be done by invoking the build script with no parameters:

$ ./build.sh

The Wave example uses a simple method to simulate the 2D wave equation and renders the results in a window using SDL.
