Environment mapping is a rendering technique used to simulate reflective and refractive surfaces by projecting a texture (often a cube map or HDR image) onto objects. In Three.js, environment mapping is typically used with materials like MeshStandardMaterial or MeshPhysicalMaterial to achieve photorealistic results. Use Case: Environment mapping is crucial for creating immersive environments in VR:… Continue reading Environment Mapping

Physics engines like Cannon.js simulate real-world behaviors such as gravity, collisions, and force interactions. When integrated with Three.js, it enables physically accurate interactions in 3D environments. Cannon.js manages the physics simulation, while Three.js handles rendering. Synchronizing these two ensures seamless realism. Use Case: Physics is essential in VR applications to: Simulate Object Behavior: Falling objects,… Continue reading Physics Integration with Cannon.js

Post-processing involves manipulating the rendered image of a 3D scene to apply visual effects. These effects are achieved by rendering the scene into a texture, processing the texture with fragment shaders, and then outputting the final image. Common post-processing effects include: Bloom: Adds a glowing effect around bright areas to simulate overexposure. Depth of Field:… Continue reading Post-Processing

Raycasting in Three.js involves projecting an invisible ray from a defined origin point in a specific direction to detect intersections with 3D objects in a scene. This technique is commonly used to enable interaction between users and the virtual environment. It calculates which objects the ray intersects and returns details about those intersections, such as… Continue reading Raycasting
