软件介绍
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>
