v0.0.3

General release

New rendering effects

• physicaly based bloom effect

• ray traced ambient occlusion

Ambient occlusion off

Ambient occlusion on

• Improved volumetric fog scattering

• Automatic exposure and average luminance

System updates

• Generally whole rendering system has been rewrite
• Improved Acceleration structure builds
• Improved queue submission granularity
• Entire Vullkan back end is now using VK_KHR_SYNCHRONISATION_2
• Fixed tone mapping on the sky box texture
• Made IBL pre-computations faster by not forcefully wait for GPU work
• And many more stability improvements
• De-noising of the visibility buffer
• Usage of push constants for the shader parameters
• VGrowableBuffer implementation and simplification of the geometry data management system

Todos

• Reimplement how lights are handled in the engine, so that volumetric scattering and shadow maps account for all light types
• Atmospheric scattering
• Implement Forward+ rendering
• And all the issues in the issue tab

Full Changelog: v0.0.2...v0.0.3

v0.0.2

Physically based path tracing update

• Micro-facet model to evaluate ray bounces
• BRDF is used to evalue surface colour from ray bounces
• Visible normal sampling to choose an incident direction wi https://jcgt.org/published/0007/04/01/paper.pdf
• Lambertian diffuse surfaces based on cosine weighted hemisphere sampling https://pbr-book.org/4ed/Reflection_Models/Diffuse_Reflection
• De-focus blur simulating camera shutter size and focal distance

New light transport calculation modle

Old reflection model, notice stretched reflections on the floor

v0.0.1

This is very early somewhat working version of the scene editor and renderer.

Features:

• Model Loading
• Scene Exporting (To glTF)
• Forward Renderer
• Area Light With LTC
• Ray Traced Pixel Perfect Shadows
• Real time path tracing (with RT cores)
• Image Based Lighting
• ACES Tone Mapping
• Scene Editor With Gizmos
• Real Time Material Customisation
• Multy threaded lazy texture loading
• Bindless descritptors for material textures
• Large scale homogeneous participating media rendering and height based fog

Ensure your GPU has support for VK_KHR_ray_tracing for GPU accelerated ray intersection tests and Monte Carlo path tracer.
