GLEngine

An OpenGL abstraction I like to use in my other projects. May update to Vulkan soon. Use the CMakeLists.txt to build the static library.

The project is a superbuild so there is no need to go find the dependencies, just build with cmake. Only works for Windows right now. Config file in src/ directory.

The rendering archicture is much like VTK but simplified and more directly coupled with OpenGL. One major difference is that it pairs an entity-component architecture with pipeline rendering architecture. This keeps it highly extensible for both data processing and dynamic complex scene's.

Modules

Common: Various common function throughout all other modules

IO: Provides various io filters

Filtering: Provides various data processing filters

Scene: Provides the Scene, SceneObjects, & Components

Rendering: Provides the renderers, render passes, & other useful rendering classes

Sources: Provides data sources

Scene

The Scene contains a set of SceneObjects not yet in graph representation.

SceneObjects contain a set of components with each component adding some functionality.

Components implement functionality and should be designed with Signals/Slots to ensure decoupled implementations.

Rendering

The renderer will render a scene to a render target. This can then be provided to a RenderWindow (common module). Multiple renderers exist.

Renderer: Does direct rendering
DeferredRenderer: Allows one to specify sets of render passes. Provided within the Rendering module are numerous passes.
RayTraceRenderer: A compute shader ray tracer.
RayTrace2dRenderer: A very unique compute shader renderer for 2d rendering.

Filtering, IO, Sources

Contains most of the filtering. Currently just image and poly data filters, IO, & sources exist.

Dependencies

OpenGL for rendering

GLEW to talk to OpenGL

GLFW for window and input management

GLM for vector math

Assimp for scene loading

tbb for parallelism
