Over the last 4 years I've been developing Skyformer, including making all the art. Technical features include:

- OpenGL for graphics, OpenAL for sound, GLFW for input

- Terrain rendered using techniques inspired by REDengine 3 with a custom terrain/world editor.

- Networking framework for co-op with TCP + custom binary protocol

- Immediate mode UI framework, SDF text rendering

- Cascaded shadow mapping with soft shadows.

- Weather simulation (with my own fake physics)

- Dynamic skydome

- Water based on Gerstner waves

- Swept-sphere collision detection and response

- Soft-particles / transparency

- God rays

- Grass rendering

- FXAA, SSAO, Bloom

- etc.

You can ask me anything and let me know if you have any feedback. Thanks!
