みなさんこんにちは。
今回はタイトルの通りTweenMax.jsとThree.jsを使用してホバーに面白いアニメーションを加えてみました。
元々あまり上記のJSを使いこなせてないので、実装できるか不安でしたがなんとか実装できたので
備忘録程度にソースを載せて置こうと思います。
使い方によってはおもしろかつおしゃれにできるのでいいかもしれません！
まずはデモから。
See the Pen three.js&tweenmax by sayuri (@giraffeweb) on CodePen.light
JSは必ずTweenMaxとthreeどちらも読み込んでください。
じゃないと動きません。
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/2.1.2/TweenMax.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/104/three.min.js"></script>
<div class="imgWrapper"> <div class="displacement-hover" data-displacement="images/displacement.png" data-speediut="1.2" data-speedout="0.9" data-intensity="0.2"> <img class="lazy" src="" data-src="images/greeting.jpg" alt="" /> <img class="lazy" src="" data-src="images/greeting2.jpg" alt="" /> </div> </div>
CSSは下記を入れておいてあげるとしっかりレスポンシブします。
なぜか最初レスポンシブがうまくいかなかったんですよね…
.imgWrapper {
position: relative;
width: 500px;
height: 300px;
&:before {
content: '';
display: block;
padding-top: 150%;
}
}
.displacement-hover {
position: absolute;
width: 100%;
height: 100%;
top: 0;
canvas {
width: 100% !important;
height: 100% !important;
}
img {
display: none;
}
}
JSの記述は以下の通り、コピペで使えます。
var hoverEffect = function(opts) {
var vertex = `
varying vec2 vUv;
void main() {
vUv = uv;
gl_Position = projectionMatrix * modelViewMatrix * vec4( position, 1.0 );
}
`;
var fragment = `
varying vec2 vUv;
uniform sampler2D texture;
uniform sampler2D texture2;
uniform sampler2D disp;
// uniform float time;
// uniform float _rot;
uniform float dispFactor;
uniform float effectFactor;
// vec2 rotate(vec2 v, float a) {
// float s = sin(a);
// float c = cos(a);
// mat2 m = mat2(c, -s, s, c);
// return m * v;
// }
void main() {
vec2 uv = vUv;
// uv -= 0.5;
// vec2 rotUV = rotate(uv, _rot);
// uv += 0.5;
vec4 disp = texture2D(disp, uv);
vec2 distortedPosition = vec2(uv.x + dispFactor * (disp.r*effectFactor), uv.y);
vec2 distortedPosition2 = vec2(uv.x - (1.0 - dispFactor) * (disp.r*effectFactor), uv.y);
vec4 _texture = texture2D(texture, distortedPosition);
vec4 _texture2 = texture2D(texture2, distortedPosition2);
vec4 finalTexture = mix(_texture, _texture2, dispFactor);
gl_FragColor = finalTexture;
// gl_FragColor = disp;
}
`;
