aer-engine
About
An OpenGL 4.3 / C++ 11 rendering engine oriented towards animation.
Features:
- Custom animation model format, SKMA, with a Blender exporter and a C++ Importer.
- Skeleton animation with GPU Skinning using Dual Quaternion Blending.
- Blend shape control (Morph Targets).
- Blend tree for sequences and clips processing.
Demos
| aura | A technical demo demonstrating the animation capabilities of the engine, with some rendering techniques (eg. HBAO on Compute Shader). |
| cuda_cs_blur | Performance comparison between a CUDA and a Compute Shader blur kernel. |
| gpu_raymarching | Raymarching on a Fragment Shader. |
| hair | dynamic hair simulation rendered with tesselation and instanciation. |
| ik_demo | A Basic Inverse Kinematic demo. |
| marching_cube | Procedural geometry generation with a marching cube algorithm on the GPU using transform feedback. |
Compilation
The build was compiled against GCC 4.9.
Compile first the engine, then the demos :
mkdir build; cd build;
mkdir engine; cd engine
cmake ../../engine -DCMAKE_BUILD_TYPE:STRING=Release
make -j4
cd ..
mkdir demos; cd demos
cmake ../../demos -DCMAKE_BUILD_TYPE:STRING=Release
make -j4Engine dependencies :
| SFML 2.1 | Used as core window manager. |
| Freeimage 3 | Image loader. |
| Armadillo 3.9 | Linear algebra library. |
| GLM 0.9.6+ | OpenGL Mathematics library. |
| GLEW 0.9.0+ | OpenGL wrangler. |
| GLSW | GLSL wrangler (provided). |
Version number corresponded to the development environment.
