Puffin OpenGL Engine ver. 2.0

3D graphics rendering engine written in C++ and OpenGL 3.3+.

Previous version of this engine is no longer developed. I decided to create a new version from scratch.

I am working on this project only in my free time after work, so new features and bug fixes are not commited often.

Features

• Phong and Blinn-Phong lighting,
• Dynamic shadow mapping (directional and point lights) with PCF,
• Fog,
• Normal mapping,
• Antialiasing,
• Skybox reflections,
• Water reflections and refractions,
• Particle effects,
• Postprocessing effects,
• HDR and bloom effect,
• Integration with IMGUI,
• Font rendering using FreeType,
• Depth of field.

Build instructions

Required libraries:

• GLM (https://glm.g-truc.net/0.9.9/index.html)
• GLEW (http://glew.sourceforge.net/)
• GLFW (https://www.glfw.org/)
• Assimp (http://www.assimp.org/)
• FreeType (https://www.freetype.org/)
• FreeImage (http://freeimage.sourceforge.net/)

On Windows I recommend using Visual Studio to compile above libraries. Building instructions of these libraries can be found on library website or in source code Readme file.

After building all of specified above libraries (except GLM, which is headers files only library) there is a need to put all following files in one directory, e.g. "binary_libs":

• glew32d.lib
• glfw3.lib
• freetype.lib
• FreeImagePlusd.lib
• FreeImaged.lib
• assimp-vc140-mt.lib

To build Puffin OpenGL Engine CMake tool is needed. Go to Puffin Engine directory, create empty Build directory and then from command line execute:

cd Build
cmake -G "Visual Studio 15 2017" -DASSIMP_INC_PATH="C:/Libs/assimp/include" -DFREE_IMAGE_INC_PATH="C:/Libs/FreeImage/Dist/x32" -DFREE_IMAGE_WRAP_INC_PATH="C:/Libs/FreeImage/Wrapper/FreeImagePlus/dist/x32" -DFREE_TYPE_INC_PATH="C:/Libs/freetype/include" -DGLEW_INC_PATH="C:/Libs/glew/include" -DGLFW_INC_PATH="C:/Libs/glfw/include" -DGLM_INC_PATH="D:/Libs/glm" -DLIBS_BINARY_PATH="C:/Libs/binary" ..

After that go to Build directory and run PuffinEngineV2.sln. Build project and then copy following *.dll files to PuffinEngineV2.exe location (PuffinEngineV2/Build/bin/Debug):

• assimp-vc140-mt.dll
• FreeImaged.dll
• FreeImagePlusd.dll
• freetype.dll
• glew32d.dll
