Deferred Pipeline with Physically Based Shading. Render demo from http://www.panda3d.org/forums/viewtop... • Specs: AMD Phenom 9550 (4x2.2GHz), Radeon HD 7750, Arch Linux, Catalyst Drivers. • CC-BY 3.0 Music by Rugi Estalagmita MidiMan: https://www.jamendo.com/en/track/6410... • Features: • Deferred rendering • Separate transparency and forward pass, too • Occlusion • SSDO, SAO and HBAO for high frequency AO • Also voxel traced AO and GI for medium/low frequency AO • Global Illumination • Cone traced Global Illumination • Also cone traced Specular Reflections • Better results than screen space reflections • Blurred reflections are cheap • Dynamic Scene Voxelization • Used for multiple effects like GI, or specular reflections • Allows correct specular refletions, even if ray is outside of view • PSSM • For directional lights, logarithmic splitting • Might support depth dependent splitting at some time • Soft Shadow Penumbras • With variance shadow maps (VSM) • SSSSS • Screen space subsurface scattering • Based on pregenerated light transport map • Multi-Hemisphere-Skybox • Atmospheric Scattering • Based on the work of Eric Bruneton, but improved and adapted for non-spheres • Shadows • Shadow updates delayed over multiple frames • Shadow atlas, also dynamic resolution adaption • Lighting: • Point Lights • Shadows via cubemap • Directional Lights • PSSM Shadows, see above • Ambient Lights • Darken or Bright • Artist controlled Global Illumination • Projector Lights • Like a perspective lens • Projection texture • Can be used for flashlights for example • Area Lights • Caster is a rectangle • Also supports projection texture • Shadows are computed by cone tracing (see GI) • Physically based shading / lighting • Tone mapping (HDR) • Also artist controlled color correction • Blur • Focal Blur • Movement Blur (edges) • Mipmap based + in place 4x4 kernel • Varying radius (DOF) • Maybe Bokeh • Tesselation Shader displacement • Approximated Chromatic Aberration
