Tool suite for Texture and 3D Model Compression, Optimization and Analysis using CPUs, GPUs and APUs

Compressonator

Compressonator is a set of tools to allow artists and developers to more easily create compressed texture assets or model mesh optimizations and easily visualize the quality impact of various compression and rendering technologies. It consists of a GUI application, a command line application and an SDK for easy integration into a developer tool chain.

Compressonator supports Microsoft Windows®, Linux and Mac builds.

Build Instructions for Windows 10 and up

To build the applications you will need to have Visual Studio 2015 installed and Qt V5.7 msvc2015 and msvc2015_64 opensource downloaded from QT website .

Note: The solution project assume QT is installed in default path (C:\Qt\5.7). If you use different path, please change the project property accordingly in the Compressonator_Root.props file.

The directory of your workspace should be as follows

• Common
• Compressonator
• LICENSE
• README.md

It is also recommended that you install and configure Visual Studio Qt5 Package extension from MSDN Visual Studio Gallery, and set in Qt Options dialog, Qt Default Version name V5.7 and path to default download path C:\Qt\5.7\msvc2015_64\bin\

https://visualstudiogallery.msdn.microsoft.com/c89ff880-8509-47a4-a262-e4fa07168408

Build Applications using Batch Files

Simply run one of the batch files from a window console.

To build the Compressonator GUI run BuildGUI.

To build the Compressonator Command line Tool run BuildCLI.

Manual Build Steps

Go to the associated directory where Visual Studio Solution Files are located as indicated in steps A through C.

All of the Applications (B, C) apart from the SDK libs (A) can be built as either Release_MD or Debug_MD 32 Bit applications.

For Application builds make sure that the default startup projects are set as follows:

(B) CommandLine solution set to CompressonatorCLI (C) GUI solution set to MainApp

Always clean and rebuild the projects

---

(A) Build the SDK libs using

\Compressonator\VS2015\CompressonatorLib.sln

This solution will create a build folder that contains DLL and Libs under \Compressonator\Build\VS2015(configuration)(platform)\

example: Compressonator\Build\VS2015\Release_MD\Win32\

---

(B) Build the Command line tool using

\Compressonator\Applications\CompressonatorCLI\VS2015\VS2015.sln

This solution will create a build folder that contains a CompressonatorCLI.exe and a new plugins folder under \Compressonator\Build\VS2015(configuration)(platform)\

The command line tool has dependencies on the following:

Qt (V5.7 and up)

• Qt5Core.dll
• Qt5Gui.dll
• qt.conf

OpenGL

• glew32.dll
• libGLESv2.dll

OpenCV

• opencv_core249.dll
• opencv_imgproc249.dll
• opencv_highgui249.dll

Required only when using Vulkan plugin

• vulkan-1.dll
• texture.vert.spv
• texture.frag.spv

Optional for image loading and saving

• qtga.dll
• qtiff.dll

The dlls above are copied to CompressonatorCLI.exe folder by "CopyFiles.bat" in the VS2015.sln.

---

(C) Build the GUI Tool using

\Compressonator\Applications\CompressonatorGUI\VS2015\VS2015.sln

This solution will create a build folder that contains a Compressonator.exe and a plugins folder under \Compressonator\Build\VS2015(configuration)(platform)\

If building in Debug_MD configuration, please make sure the working directory is in \Compressonator\Build\VS2015\Debug_MD(platform)\

The GUI tool has dependencies on Qt(V5.7 and up) - These file are copied to the Compressonator.exe folder when the project solution builds and run "CopyFiles.bat".

Build Instructions for Linux CompressonatorCLI command line application

Note: For all unix build with this scripts, Do NOT move the shell/batch scripts provided (run in the same folder (Compressonator/Applications/CompressonatorCLI/Make/))

For Ubuntu build (****only v14.04LTS and v16.04LTS build tested, WSL is tested as well):

run initsetup_ubuntu.sh to install the required packages for command line app:

• cmake at least 2.8.12
• gcc-6 and g++-6 (v6.3.0)
• glew and opengl (libglew-dev libegl1-mesa-dev)
• qt5 at least 5.5.1
• openexr v2.2
• opencv v2.49
• Boost at least 1.59 (filesystem and system lib)

run buildCLI_ubuntu_cmake.sh to build (or rebuild) all the dependencies libraries with CompressonatorCLI executable generated in the same folder

Note: For more details on unix build, please refer to readme.txt

Build Instructions for Linux Example command line application

To build the static Compressonator library or the Example command line applicatio under folder "Compressonator\Examples" you need to have the latest GCC v6.3.0 toolchain installed (tested with 6.3.0 on WSL).

There are makefiles prepared for you.

• static library: makefile location "Compressonator/Make/ExampleMake/", output in "Compressonator/Build/Linux/libcompressonator.a"
• Example CLI: makefile location "Compressonator/Examples/Make", output in "Compressonator/Build/Linux/Example/cmpcli"

Example only take dds file as input. For more file format input, please try build CompressonatorCLI. Usage for the Example CLI: ./cmpcli src.dds out.dds ATC_RGB 1
