The document provides an overview of the technical details and effects used in a platform demo created in GDC 2011. It describes the automatic and interactive camera modes that orbit and follow characters around the platform. It also provides statistics on triangle counts and frame rates achieved on different hardware configurations. Key effects highlighted include HDR tonemapping, bloom, depth of field, deferred shading, sky rendering, day/night cycles, water simulation, soft particles, pathfinding, terrain generation, and screen-space ambient occlusion. Lights, shadows, depth of field, and other effects are configurable directly in the editor.
