Camera Post-Processing

The Camera class integrates a post-processing chain that runs after the main scene render. Effects are managed by the camera's internal Compositor, and the common effects can be enabled directly through camera properties.

Overview

Post-processing effects read the rendered framebuffer and produce a new image. Most application code should use the built-in camera properties, such as camera.bloom = true or camera.bloomIntensity = 1.2.

Built-in effects:

Effect	Class	Purpose
Tonemapping	Tonemap	Converts HDR scene color to display color
FXAA	FXAA	Fast edge smoothing
TAA	TAA	Temporal antialiasing with jitter and accumulation
Bloom	Bloom	Glow from bright areas
SSR	SSR	Screen-space reflections
SSGI	SSGI	Screen-space diffuse global illumination using opaque HDR history
SSAO/SAO	SAO	Screen-space ambient occlusion
Motion Blur	MotionBlur	Blur from camera or object motion
Skin SSS	SkinSSS	Skin subsurface scattering, used with SkinMaterial; see Skin and Subsurface Scattering
Color Adjust	ColorAdjust	Saturation, contrast, hue, and sharpen adjustment
Grayscale	Grayscale	Grayscale conversion for custom compositor chains

Camera Properties

The camera owns the commonly used effect instances and appends them to its compositor automatically. Typical usage:

camera.HDR = true;
camera.toneMap = true;
camera.toneMapExposure = 1.1;

camera.bloom = true;
camera.bloomThreshold = 0.85;
camera.bloomIntensity = 1.2;

camera.FXAA = true;
camera.TAA = true;
camera.motionBlur = true;
camera.motionBlurStrength = 0.5;

For custom post-processing chains, use camera.compositor and append your own AbstractPostEffect instances.
