ThreeJS-3D graphics rendering library

Example

In Three.js, a 'Scene' is a container that holds all the 3D objects, lights, and cameras. You add objects to the scene to visualize them.

Scenario

A designer creating a virtual showroom can use the scene object to organize different products, such as cars or furniture, and display them interactively.

Example

Three.js provides different types of cameras, such as PerspectiveCamera (which mimics how human eyes perceive depth) and OrthographicCamera (used for 2D-like projections).

Scenario

For a flight simulator game, you might use a PerspectiveCamera to give users a realistic view from the cockpit, complete with depth perception.

Example

A 'Mesh' in Three.js is an object that consists of a geometry (shape) and a material (appearance).

Scenario

A game developer can create a character model using BoxGeometry (for the body) and SphereGeometry (for the head), and apply textures to give it a realistic appearance.

Example

Three.js supports various types of lights, such as PointLight, DirectionalLight, and AmbientLight, and allows you to cast shadows from objects.

Scenario

In an architectural visualization of a house, you can use DirectionalLight to simulate sunlight and cast realistic shadows to enhance the visual appeal of the space.

Example

Materials in Three.js define the look of objects, and textures can be applied to give objects more detail. Common materials include MeshBasicMaterial, MeshStandardMaterial, and MeshPhongMaterial.

Scenario

A product designer can apply high-quality textures to a 3D model of a smartphone to show realistic materials like glass and metal, helping customers visualize how the product would look in real life.

Example

Three.js includes an animation system that allows you to animate object properties such as position, rotation, or scale over time.

Scenario

In an interactive website that showcases different products, users can click on a product to see it rotate 360 degrees, all handled smoothly through Three.js's animation framework.

Example

Post-processing in Three.js allows you to apply visual effects after rendering, like bloom, depth of field, or motion blur.

Scenario

For a VR experience, post-processing effects can be applied to enhance immersion by simulating real-world camera effects such as lens flares or motion blur during fast movements.

Example

Three.js can integrate with physics engines like Cannon.js or Ammo.js to simulate realistic physical interactions like gravity, collisions, and rigid-body dynamics.

Scenario

In a virtual physics lab, students can experiment with rolling a ball down a ramp and observe realistic gravity and collision effects, thanks to Three.js's integration with physics engines.
