WebGL 库:twgl.js

jopen 9年前

twgl.js 是一个使 WebGL API 更佳简洁的库。(WebGL 是一种 3D 绘图标准)

示例:

<canvas id="c"></canvas>  <script src="../dist/twgl-full.min.js"></script>  <script>    var gl = twgl.getWebGLContext(document.getElementById("c"));    var programInfo = twgl.createProgramInfo(gl, ["vs", "fs"]);    var arrays = {      position: [-1, -1, 0, 1, -1, 0, -1, 1, 0, -1, 1, 0, 1, -1, 0, 1, 1, 0],    };    var bufferInfo = twgl.createBufferInfoFromArrays(gl, arrays);    function render(time) {      twgl.resizeCanvasToDisplaySize(gl.canvas);      gl.viewport(0, 0, gl.canvas.width, gl.canvas.height);      var uniforms = {        time: time * 0.001,        resolution: [gl.canvas.width, gl.canvas.height],      };      gl.useProgram(programInfo.program);      twgl.setBuffersAndAttributes(gl, programInfo, bufferInfo);      twgl.setUniforms(programInfo, uniforms);      twgl.drawBufferInfo(gl, gl.TRIANGLES, bufferInfo);      requestAnimationFrame(render);    }    requestAnimationFrame(render);  </script>
