Redqueen

A Simple Production Renderer

To give a shot:

1. Install Visual C++ Redistributable https://www.microsoft.com/en-us/download/details.aspx?id=48145
2. Double click "tutorialxx.exe" in the "bin" folder

To create your app:

1. Install Visual Studio Community https://www.visualstudio.com/en-us/products/free-developer-offers-vs.aspx
2. Select "Release" and "x64" in Configuration Manager to build your application

Features:

• Extremely simple API
• Small memory footprint
• Reasonably fast
• Integrators:
  • Unidirectional path tracing with MIS for outdoor scenes
  • Progressive final gathering for interior scenes
  • Photon mapping for SDS paths
• Primitives: particle / cylinder (with runtime tessellation) / triangle / tetragon / cube (for voxel art)
• OBVH with refitting / treelet restructuring / child node reordering for fast occlusion test
• Multi-level instancing (40559990463 triangles in the image below)
• Deformation blur with consistent motion
• Light sources: point / parallel / geometry / sky
• Per light AOVs
• AOVs (Per vertex user data can be easily obtained)
• Uber shader (The parameters are automatically interpreted as those of d'Eon's model when applied to hair strands)
• Brute-force SSS
• Three-dimensional procedural shaders using Voronoi cells
• Redqueen does not use Embree

Goals:

• Compact - reduce memory consumption
• Simple - so that people can use without manual
• Fast - make best use of the instruction sets of modern CPUs
• Robust - never crashes
• Free - targeting at individuals and small studios

I'm working on a new version.
