Each time we move our mouse, TweenMax will update the position and the rotation smoothly. Click to jump and feel sleepy :). You can click on an image and it will expand to a larger version while some other content shows up (just a mock-up). Three.js WebTextures are generally images that are most often created in some 3rd party program like Photoshop or GIMP. For other cases you will need to build or load custom geometry and/or modify texture coordinates. I'm not 100% sure at what level to explain them but I will try. But you can implement the same concepts using other libraries. ); float offsetProgress = mix(offsetIn,offsetOut,u_direction); pos.z += stickEffect * u_offset * stickProgress u_offset * offsetProgress; gl_Position = projectionMatrix * modelViewMatrix * vec4(pos, 1.0); }.
