Three.js

  • Discover the basics of Three.js, a powerful JavaScript library for creating 3D graphics on the web. This beginner's guide will walk you through setting up Three.js, adding 3D objects, and animating your scenes. Perfect for developers looking to enhance their web applications with stunning 3D visuals.

Cube

  • Begin by creating a simple scene with a cube. 

Adding 3D object

  • You can experiment cube with different colors, materials.

Cast Shadow

  • This code enables shadow casting for all meshes in a cube object.

Creating Ground Plane

  • Create a shadow-receiving ground plane and position the camera 5 units away in the scene for perspective.

Add Directional Light

  • Add a bright directional light that casts shadows to illuminate the scene effectively.

Defining animation variables

  • Defining animation variables sets initial states for controlling rotation and animation speed in a Three.js scene. 

function start animate

  • The animate function keeps the scene updated and renders object rotations, like the cube, when rotation is activated.

function stop animate

  • The stopAnimate function stops the cube from rotating and animating, ensuring it continues to cast shadows in the scene.

function toggleRotation

  • toggleRotation function changes the object's rotation direction on all axes, allowing control over its animation.

function showShadow

  • The showShadow function enables or disables shadows in the scene by adjusting properties of the cube and ground.

function ambient light

  • The showAmbientLight function adds a soft background light to the 3D scene, improving visibility and enhancing the scene's overall appearance.

function Directional Light

  • The showDirectionalLight function adds a directional light to the scene, enhancing 3D visuals with adjustable shadows and specific lighting direction.

function showSpot light

  • The showSpotLight function adds a focused spotlight to enhance directional lighting and shadow effects in the 3D scene.

GUI

  • The GUI interface simplifies adjusting cube rotation, camera position, and scaling in the 3D scene.

adding color

  • This code makes it easy to choose colors by adding interactive color pickers for each property in the obj object, simplifying color customization.

Adding Buttons

  • Buttons are used to provide interactive controls for users in the web page. Each button in the provided HTML code is associated with an onclick attribute that calls a specific JavaScript function when clicked.

Creating Texture and Creating path on which cube will move

  • The textured cube in the code is used to create visually appealing 3D graphics by applying an image ('images.jpeg') onto its surface. This technique enhances realism and detail in 3D scenes.

  • This code generates a 3D path using specified points and displays it as a red line in a Three.js scene. It also makes sure that any 3D model inside a cube will cast shadows. This is helpful for visualizing routes or moving objects along a defined path in a 3D space.
