Ultimately intended to be the successor to/replacement for my older gaming engine, GTE.\n\n## Current features:\n\n* Multi-pass and single-pass forward rendering\n* Model import: Support for many industry standard formats via the Assimp library\n* Image import: Support for many industry standard formats via the DevIL library\n* Dynamic shadows via shadow maps\n  - Support for directional and point lights (2D and cube shadow maps)\n  - Multiple cascade levels for directional lights\n  - Soft edges through PCF\n* Physically-based rendering\n  - Cook-Torrance BRDF\n  - Image-based ambient lighting for global illumination approximation\n  - HDR support\n  - Gamma correction support\n* Skeletal animation:\n  - Vertex skinning\n  - Animation blending\n* Particle systems\n* Scene-graph API\n* Render-to-texture capability\n* Screen-space ambient occlusion\n\n## External dependencies:\n\n- Assimp (Asset Import Library)\n- DevIL image library\n\nDynamic versions of the above libraries are required.\n\n## Building\nStandard CMake build is currently supported and an out-of-source build is recommended. To generate the make files, execute the command relevant to the desired configuration (Linux/Unix examples shown):\n\nDebug:\n\n    cmake -G \"Unix Makefiles\"\n\nRelease:\n\n    cmake -DCMAKE_BUILD_TYPE=Release -G \"Unix Makefiles\"\n    \nA release build will be significantly more performant.\n\n#### External Libraries\nYou will need to modify the locations of the Assimp and DevIL libraries in CMakeLists.txt. The relevant variables are DEVIL_DIR and ASSIMP_DIR.\n\n#### Linux notes\nIn order for CMake to find your OpenGL installation on some Linux distributions, it may be necessary to run the following command to install the Mesa development packages:\n\n     sudo apt-get install libgl1-mesa-dev\n\nThe DevIL library can be installed via:\n\n     sudo apt-get install libdevil-dev\n     \nThe Assimp library can be installed via:\n\n     sudo apt-get install libassimp-dev\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmkkellogg%2Fcore","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmkkellogg%2Fcore","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmkkellogg%2Fcore/lists"}
