Dungeon Dave!

---

• A first-person FPS in the style of games like Doom and Quake.
• The Dungeon Dave engine is built fully from scratch, ensuring optimal performance for all platforms.

Rendering Techniques

• Normal Mapping

• Parallax Occlusion Mapping (heightmaps are generated at runtime based on objects' albedo textures - currently disabled though)

• Exponential Shadow Mapping (for soft shadows)

• Cascaded Shadow Mapping (with blended depth layers - this makes transitions between depth layers a smooth fade)

• God Rays (based on this technique from Nvidia, but works in light-space rather than in screen-space, which allows for the light volumes to remain when the camera is turned away from the sun)

• Precomputed Raytraced Ambient Occlusion (a shader traces rays from each point in the scene to compute a set of occlusion values - and caches this on disk - and at runtime, the main shader tricubically interpolates from a 3D texture to fetch these occlusion values)

More To Know

• The renderer is fully physically based, and employs a metallic/roughness material system.
• The renderer is a typical forward renderer, and utilizes a depth prepass.
• Shadows and god rays work perfectly for translucent objects!
• Billboard sprites are fully animated.
• The voxelized world uses greedy meshing to minimize the size of the overall world mesh.
• Levels use a set of original soundtracks developed by Adam Winograd. In-game sound effects use OpenAL for a surround-sound effect.
• I drew most of the pixel art with Aseprite, including the skyboxes (which employ cylindrical projection).
