The simplest and possibly most common is the Google Cardboard style of VR which is basically a phone put into a face mask. This kind of VR has no controller so people have to come up with creative solutions for allowing user input. The most common solution is “look to select” where if the user… Continue reading VR – Look to Select

LatheGeometry
Creates meshes with axial symmetry like vases. The lathe rotates around the Y axis. Code Example const points = []; for ( let i = 0; i < 10; i ++ ) { points.push( new THREE.Vector2( Math.sin( i * 0.2 ) * 10 + 5, ( i – 5 ) * 2 ) ); }… Continue reading LatheGeometry
Blender Skybox Addon
What is a Skybox? A skybox is a 360-degree environment that surrounds a 3D scene, simulating a realistic sky, space, or landscape background. Instead of rendering distant objects in real-time (which is computationally expensive), skyboxes use pre-rendered textures on a cube or sphere, creating the illusion of an infinite world. Skybox Formats: Cubemap (6-sided texture)… Continue reading Blender Skybox Addon
Optimizing Meshes in Babylon.js with Mesh Optimizer
Why Optimize Meshes? Before diving into Babylon’s mesh optimizer, let’s understand why optimization is necessary: Faster Rendering – Reducing the number of vertices and polygons speeds up GPU processing. Better Performance on Low-end Devices – Optimized meshes reduce memory usage, improving performance on mobile and older hardware. Smaller File Sizes – Optimized models load faster,… Continue reading Optimizing Meshes in Babylon.js with Mesh Optimizer
Custom Shaders in WebGL
WebGL is a powerful graphics API that enables developers to create interactive 3D graphics in the browser. At the heart of WebGL’s rendering pipeline are shaders, small programs that run on the GPU to determine how objects appear on the screen. Custom shaders allow for stunning visual effects, from realistic lighting to artistic distortions. In… Continue reading Custom Shaders in WebGL
The Rise of Theatre.js: Revolutionizing Web Animation and Storytelling
In the ever-evolving world of web development, creating immersive and engaging user experiences has become a top priority. From interactive websites to dynamic web applications, developers are constantly seeking tools that allow them to push the boundaries of creativity. Enter **Theatre.js**, a powerful JavaScript library that is revolutionizing the way we think about web animation… Continue reading The Rise of Theatre.js: Revolutionizing Web Animation and Storytelling
Environment Mapping
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 Integration with Cannon.js
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
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
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
