Each light casting shadows will render the scene in a specific way and output that we call “shadow map”. This shadow map is then used to know if a surface is in the shade or not. By default, that shadow map resolution is rather low in order to maintain solid performance. Fortunately, we can change… Continue reading Configuring the shadows

Post-Processing Effects
Post-Processing Effects are image-based techniques applied after the main rendering pass to enhance the visual output. Common effects in Three.js include bloom, depth of field, motion blur, and vignette. Use Case: Post-processing is essential for adding cinematic flair or guiding the viewer’s focus in applications like movies, games, and interactive experiences. Advantages: Improves the mood… Continue reading Post-Processing Effects
Environment Mapping
Environment Mapping involves using a texture (often a cube map or equirectangular image) to simulate reflections and ambient lighting in a scene. In Three.js, it is commonly applied using scene.environment or as a reflection map on materials. Use Case: Environment mapping is crucial for creating reflective surfaces like glass, water, or polished metals in 3D… Continue reading Environment Mapping
Physically Based Rendering (PBR)
Physically Based Rendering (PBR) is a shading and rendering approach that aims to simulate how light interacts with materials in the real world. In Three.js, PBR is implemented through materials like MeshStandardMaterial and MeshPhysicalMaterial. Use Case: PBR is widely used in gaming, product visualization, and AR/VR applications to achieve photorealistic appearances of materials and surfaces.… Continue reading Physically Based Rendering (PBR)

Tone Mapping
Overview: Tone mapping is a technique used to convert high dynamic range (HDR) images to a lower dynamic range suitable for display. In Three.js, tone mapping enhances the realism of scenes by accurately representing light and shadow. Use Case: Tone mapping is essential for applications requiring realistic lighting, such as architectural visualizations or photorealistic renderings.… Continue reading Tone Mapping
Shaders
Overview: Shaders are small programs that run on the GPU and dictate how vertices and pixels are processed in Three.js. They enable developers to create custom visual effects, from simple color changes to complex materials and lighting effects. Use Case: Shaders are perfect for scenarios requiring unique visual styles or effects that go beyond the… Continue reading Shaders
GSAP (GreenSock Animation Platform)
Overview: GSAP is a powerful JavaScript library for creating high-performance animations. When integrated with Three.js, it allows developers to animate properties of Three.js objects with ease, providing smooth transitions and complex sequences. Use Case: GSAP is ideal for creating intricate animations in interactive applications, games, or presentations where fluid motion is critical. Advantages: Offers a… Continue reading GSAP (GreenSock Animation Platform)
Frustum Culling
Overview: Frustum culling is an optimization technique used in Three.js to enhance rendering performance by eliminating objects outside the camera’s view. By determining which objects are within the camera’s frustum (the visible area), it avoids unnecessary processing for objects that won’t be seen. Use Case: Frustum culling is essential for applications with complex scenes, such… Continue reading Frustum Culling
