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 -j4

Engine 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.

  • Do you think you could apply this to the Fork of blender UPBGE?

    Do you think you could apply this to the Fork of blender UPBGE?

    We have a game engine that is starting to really be something amazing

    https://github.com/UPBGE/upbge

    Do you think you could help the developers implement your GPU armature skinning?

    this is one of the final pieces the engine needs to be both open source and free, but compete with the other big engines.
