Built-in Effects

Built-in effects are high-performance post-processing effects managed automatically within the system for performance optimization and depth buffer utilization.

1. Features & Usage

Unlike general effects, you do not need to create an instance yourself or add it via addEffect(). You can control them instantly by simply changing the property values of the PostEffectManager.

• Access Path: view.postEffectManager
• Activation Method: Use Boolean properties such as useSSAO and useSSR.

2. SSAO (Screen Space Ambient Occlusion)

SSAO creates subtle shadows in corners or where objects overlap, maximizing three-dimensionality.

Activation & Configuration

// 1. Enable SSAO
view.postEffectManager.useSSAO = true;

// 2. Detailed settings (optional)
const ssao = view.postEffectManager.ssao;
ssao.radius = 0.5;      // Shadow radius
ssao.intensity = 1.0;   // Shadow intensity
ssao.useBlur = true;    // Whether to use blur to remove shadow noise

3. SSR (Screen Space Reflection)

SSR implements real-time reflections using information on the screen. It is effective for creating effects where the surrounding environment is reflected on floors or walls.

[Experimental Feature]

Currently, SSR is an experimental feature. Noise or visual artifacts may occur depending on the environment, so please apply it carefully after reviewing the results.

Activation & Configuration

// 1. Enable SSR
view.postEffectManager.useSSR = true;

// 2. Detailed settings (optional)
const ssr = view.postEffectManager.ssr;
ssr.reflectionIntensity = 1.0; // Reflection intensity
ssr.maxDistance = 15.0;        // Maximum reflection tracking distance
ssr.maxSteps = 64;             // Reflection calculation precision (number of steps)

Key Summary

• Built-in effects are fixed-stage effects activated by property settings alone.
• They are more performant than manual implementation because they share depth information within the system.
• They can be controlled individually via the useSSAO and useSSR properties.
