BRE is a rendering framework or engine which purpose is to have a codebase on which develop techniques related to computer graphics. Among BRE features we can include:
- Task-based architecture for parallel draw submission.
- Asynchronous command execution/command recording
- An easy to read, understand and write scene format
- Configurable number of queued frames to keep the GPU busy
- Deferred shading
And the rendering techniques implemented at the moment are
- Color Mapping
- Texture Mapping
- Normal Mapping
- Height Mapping
- Color Normal Mapping
- Color Height Mapping
- Skybox Mapping
- Diffuse Irradiance Environment Mapping
- Specular Pre-Convolved Environment Mapping
- Tone Mapping
- Screen Space Ambient Occlusion
- Gamma Correction
The directory structure is:
/BRE Source code
/external Third-party libraries
/doc Documentation (doxygen) - Open index file.
In the Visual Studio solution, you can check scene files in BRE/Executable/resources/scenes. I use YAML format for scenes. You can open /doc/index.html file to read the Doxygen documentation You can check the following blog entry where I constantly add new articles about BRE (architecture, techniques, classes, etc). It is https://nbertoa.wordpress.com/bre/
I write a blog where I explain its design, and how I applied/learned the techniques I use. The blog link is https://nbertoa.wordpress.com/
