com.io7m.r2

The com.io7m.r2 package implements an aggressively minimalist deferred rendering system.

Features

• Deferred rendering system for rendering hundreds of dynamic light sources at a time.
• Batched instancing for rendering large numbers of instances with one draw call.
• Billboarded instances for rendering particle systems and foliage.
• Dynamic spherical, directional, and projective lighting.
• Optional specular lighting.
• Light clip volumes for preventing light volumes from leaking.
• Variance shadow mapping for soft-edged per-pixel shadows.
• Artist-controllable alpha stippling for crossfading opaque instances.
• Emission and glow filters for simulating emissive surfaces and bloom.
• Normal mapping for per-pixel control over surface lighting.
• Command-line tools and API to generate consistent tangent vectors for meshes for normal mapping.
• Environment mapping for simple pseudo reflections.
• High quality haloless screen-space ambient occlusion (SSAO).
• Generic refraction for simulating refractive surfaces.
• Simple forward renderer for translucent instances.
• Logarithmic depth by default, supporting planetary-scale scenes.
• Box blur and bilateral depth-aware blur filters.
• Fog filters for simple postprocessed atmospheric fog.
• FXAA antialiasing.
• Reusable and heavily documented GLSL shader library. Integrated with sombrero for consuming and publishing shader modules.
• Safely extensible via strongly-typed shader interfaces.
• Scene independent: The package provides batching and does not require the user to use a complicated and error-prone scene graph or any kind of baked-in visibility determination.
• Heavily documented including Javadoc and full design and implementation manual.
• Strongly typed interfaces with run-time checking to catch programming mistakes early.
• Written in pure Java 8 for platform independence.
• Works on JOGL or LWJGL via jcanephora.
• Works on any OpenGL 3.3 implementation.
• High converage automated test suite.
• ISC license.
