Bak-Tsiu — Examining Every Pixel Differences

Introduction

Bak-Tsiu is an image viewer designed for comparing and examining differences among multiple images.

The motivation behind the implementation of Bak-Tsiu is that I found there are no convenient tools to examine pixel differences among multiple rendering results of different anti-aliasing algorithms and their corresponding configurations. Bak-Tsiu is a tool derived from my personal workflow, it provides split and side-by-side view along with close-up RGB values inspection. For more details, please see the quickstart guide or watch the intro video.

Compiling

Bak-Tsiu is trying to be self-contained as much as possible. Most third party libraries are contained in the same repository. However, there are still two external submodules need to be downloaded:

• GLFW
• OpenEXR [optional]

All relevant resources like fonts and shaders are all embedded into the execution file. Thus we only need to take single execution file for distribution.

Windows

To fetch the entire project with submodules, please add --recursive flag in clone command:

$ git clone --recursive https://github.com/shihchinw/baktsiu.git
$ cd baktsiu
$ mkdir build
$ cd build
$ cmake -G "Visual Studio 15 2017 Win64" -DUSE_OPENEXR:BOOL=ON ..

You can open generated baktsiu.sln to build the solution as usual, or execute msbuild baktsiu.sln -target:Build from console.

Linux and Mac OS

$ git clone --recursive https://github.com/shihchinw/baktsiu.git
$ cd baktsiu
$ mkdir build
$ cd build
$ cmake -G "Unix Makefiles" -DUSE_OPENEXR:BOOL=ON ..
$ make
$ sudo make install
