This is "libcgt", my library of computer graphics tools. It is MIT licensed.

It targets Windows 8.1+ and 10, OS X Yosemite, and Android (armeabi-v7a and arm64-v8a). It has only been extensively tested on Windows x64.

libcgt comprises a number of modules, each of which is a static (default) or dynamic library. We list the module dependencies below.

core:

• None.

GL:

• GPU drivers with OpenGL >= 4.5.
• GLEW >= 2.0.0.

cuda:

• NVIDIA CUDA Toolkit 7.5.
• NVIDIA CUDA Samples (for cutil).

camera_wrappers/Kinect1x:

• Microsoft Kinect SDK 1.8.

camera_wrappers/OpenNI2:

• OpenNI 2.2.0.33 Beta.

QDirectX:

• Qt 5.
• Microsoft DirectX SDK (10 depends on 10, 11 depends on 11)

qt_interop:

• Qt 5.

opencv_interop:

• OpenCV 3.0 or 3.1.

These modules used to work but needs some TLC to get to build again on all platforms.

math:

• Intel Math Kernel Library 10.3+
• SuiteSparse 3.6.1 (http://www.cise.ufl.edu/research/sparse/SuiteSparse/)

video:

• ffmpeg 0.5

On desktop, libcgt uses CMake 3.4.3+.

Set the CMAKE_PREFIX_PATH environment variable to where dependencies live. For example, I put all my libraries under c:\opt\local, which have as subdirectories bin, include, and lib. To find GLEW, do the following:

set CMAKE_PREFIX_PATH=%CMAKE_PREFIX_PATH%;c:\opt\local

To find OpenCV, use: set OpenCV_DIR=c:\opt\local\opencv-3.1.0\build

By CMake convention, you should put the generated Visual Studio solution in a build directory: $ mkdir build $ cmake-gui ..

MacPorts versions of all dependencies work great out of the box. CMake is able to find them from /opt.

By CMake convention, you should put the generated Xcode project or Makefiles in a build directory: $ mkdir build $ cmake-gui ..

Qt 5 from the default repository is sufficient. $ sudo aptitude install qt5-default

You will need download and build more recent versions of GLEW and OpenCV. I put these libraries under ~/opt/local. I built GLEW under ~/opt/local, which contains as subdirectories bin, include, and lib. Add the following to your .bashrc:

export CMAKE_PREFIX_PATH=$CMAKE_PREFIX_PATH:~/opt/local

To build and install OpenCV:

cd <opencv_dir> mkdir build cd build cmake-gui -D CMAKE_INSTALL_PREFIX=~/opt/local .. make -j32

~/opt/local should contain as subdirectories bin, include, lib, and share.

set OpenCV_DIR=~/work/libs/opencv-3.1.0

Apparently, gcc-4.8 has trouble building libcgt. We use Clang 3.5+ instead:

mkdir build cd build cmake -DCMAKE_CXX_COMPILER=clang++-3.5 -DCMAKE_INSTALL_PREFIX=~/opt/local ..

cd build_android ./build.sh
