FAQ’s
1. How does Three.js handle user interaction?
Three.js enables user interaction by responding to events such as mouse clicks and movements. Developers can use this feature to create interactive interfaces having 3D look.
2. What is a geometry in Three.js?
In Three.js, a geometry defines the shape of a 3D object, such as a cube or sphere. We use this to create an intercative UI. It specifies the vertices, edges, and faces that make up the object.
3. Why is the scene graph important in Three.js?
Because it is important for organizing and managing the hierarchy of 3D objects in a scene. It helps developers to structure and control the relationships between different elements so that they can build unique graphs.
4. How does Three.js support animation?
Three.js supports animation by allowing developers to update the properties of 3D objects over time. It allows changes in position, rotation, and scale, providing the basis for dynamic and engaging visual experiences. These all features make animation possible.
5. How can Three.js contribute to responsive design?
Three.js supports responsive design by allowing developers to create 3D content that adapts well to different screen sizes and resolutions, ensuring a consistent user experience across devices. That’s why it is highly used in creation of interactive 3D UI.
ThreeJS
Three.js is an open-source JavaScript library that is used to display graphics, 3D and 2D objects on the web browser. It uses WebGL API behind the scenes. It allows you to use your GPU(Graphics Processing Unit) to render the Graphics and 3D objects on a canvas in the web browser. since we are using JavaScript we can also interact with other HTML elements. Three.js was released by Ricardo Cabello in April 2010.
