Flow Engine

A 3D Engine written in OpenGL just for fun. :smile:

The goal of this project is to create a generic API for realistic graphics (Physically Based Rendering) and physics.

The API is completely open source, so you are free to do whatever you want with it :wink:.

It will also be the basis for another project I'm working on (a custom file format dedicated to Blender) it will be a good opportunity to test if the models load correctly.

Libraries

As I am developing on Linux, the graphics library I use for this projet is OpenGL 3.3.

To build the core and graphics engine faster, I rely on these other libraries:

• [GLFW 3] (http://www.glfw.org/index.html) - for the Window / Event system
• [GLEW] (http://glew.sourceforge.net/) - to fetch OpenGL pointers
• [GLM] (http://glm.g-truc.net/0.9.8/index.html) - a math library for OpenGL
• [SOIL] (http://www.lonesock.net/soil.html) - to load images as a series of pixels for OpenGL

In the long run, these libraries will be replaced by custom ones. OS targeted : Windows / Linux

3D Engine

The 3D engine has the following features: - window system - keyboard and mouse event system - camera handling (translation, orientation) - point lights (CookTorrance) - model loading (.obj) - component based entities - mesh factory - material system

Check the release notes for more details.

Here are some examples:

2D Engine

The renderer can render up to 60 000 sprites on the screen at 500 fps with the following features:

• Basic shader loading
• Object oriented buffer & vertex arrays
• Texture loading and texture arrays (32 textures on the array)
• Mask texture rendering (only one, taking the entire screen)
• Multiple layers of sprite
• Scene graphs
• Multiple render targets (screen or buffer)
