Techniques

Here's a list of techniques used in OpenSpades:

• Ocean Simulation - r_water
• Soft Sprite - r_softSprite
• Local Illumination
• Shadow Maps - r_modelShadows for dynamic models
• Cascaded Shadow Maps - MSDN
• Sparse Shadow Maps
• Variance Shadow Maps - Paper
• Ray-traced Volumetric Light - r_fogShadow, Nvidia's white paper
• Global Illumination - r_radiosity
• Simple Ambient Occlusion - this is done even when r_radiosity is set to 0
• Ray-traced Ambient Occlusion
• Reflective Shadow Maps - Paper
• Post Processing
• Screen-Space Motion Blur - r_cameraBlur
• Fast Approximate Anti-Aliasing - r_fxaa
• Lens Simulation - r_lens
