Features

This page lists the already implemented Features, the features to be implemented, and the TODO list:

Features

This is the stuff the pipeline already supports:

• Full deferred rendering
  • Clustered deferred lighting
• Physically based shading
• Directional shadows with PSSM
  • PCF filtering
  • PCSS shadow filtering
• Atmospheric scattering supporting different scattering models
  • Eric Bruneton
  • Hosek & Wilkie
• Screen space ambient occlusion:
  • SSAO
  • SSVO
  • HBAO
  • AlchemyAO
  • UE4AO (Modified AlchemyAO as proposed in UE)
• Bloom
• Color correction:
  • Tonemapping with many operators:
    • Reinhard (Luminance and Color based)
    • Uncharted 2
    • Exponential
  • Dynamic Exposure
  • Film grain
  • Vignetting
  • Chromatic Aberration
  • Color LUT
• SMAA / FXAA
• Subsurface shading
  • Backface translucency
• SSLR
  • Screen space local reflections (bit buggy right now)
• Environment Probes
  • Up to 341 per scene
• Volumetric Clouds
• (experimental) Voxel cone tracing
• and much more ...

To be implemented

This are the features I really want to get into the Pipeline at some point, ordered by their importance:

• Forward shaded objects (in progress)
  • Particles
  • Transparent objects
• Eventually DoF (I do not like this effect, so its on the end of my todo list, but I will implement it for completeness)

TODO List

This is my personal todo-list off stuff that I want to get done (not ordered):

• Support for lights attached to node paths
• Improve SSLR (Maybe not required with VCT)
• Only update shadow sources in frustum
• Improve clouds
  • Examine better rendering technology than voxels
• VSM for terrain shadows
• Only update scattering cubemap if the time of day changed
• Reimplement settings loader
• Move plugins out of rpcore to rpplugins/ (or similar name)
• Better workflow for exporting lights and environment-probes (Update: Fix light export)
• Rename rp_object to rpobject
• Support for sky occlusion to properly lit closed rooms (and SkyAO)
• Use low-precision depth (16bit) for everything
• Instead of using no ambient for envprobes, use sky occlusion to determine ambient
• Improve and fix Voxel Cone Tracing
• Only use relevant lights for forward shading (Quadtree maybe?)
• Support for envprobes with depthmap, to avoid bleeding
• Smooth frame delta for motion blur so we have no spikes
