The Phoenix Engine is our first large-scale game engine. We began with using Direct3D9/OpenGL 2.0 with fixed-function pipeline support as the base. We quickly upgraded it to a programmable pipeline, which we fully utilize throughout the rendering process. We have also expanded the base to include Direct3D10/11 and OpenGL 3.0 support.

The Phoenix Engine currently utilizes the following technologies:

General

• APIs: OpenGL 3.x, Direct3D 9/10/11
• Instancing support
• Resource Manager based on Red-Black tree
• Shader Manager (w/ Material Manager)

Scene Management

• Octree
• Terrain Engine
• Object Loading (.3ds)
• View-Frustum Culling

Rendering

• Deferred Lighting
• Deferred Shading
• Instancing

Bumpmapping

• Normal
• Parallax
• Parallax Occlusion

Effects

• Particles
• Heat Haze
• *Glass Refractions

Environment

• Fog Volumes (Box, Ellipsoid)
• Volumetric Clouds
• Procedural Sky
• Water Reflection/Refraction

Terrain

• Quad-tree LOD
• Geomippmapping (4x4 sectors)
• View-Frustum Culling

Post Processing

• Global Fog
• High Dynamic Range Lighting (w/ Blue Shift)
• Depth of Field
