The following shows the render function of the textbook example code "perspective2.js". What coordinate system is used for the vec3 for "eye"?

function render(){

gl.clear(gl.COLOR_BUFFER_BIT | gl.DEPTH_BUFFER_BIT);

eye = vec3(

radius*Math.sin(theta)*Math.cos(phi), radius*Math.sin(theta)*Math.sin(phi), radius*Math.cos(theta));

modelViewMatrix = lookAt(eye, at, up);

projectionMatrix = perspective(fovy, aspect, near, far);

gl.uniformMatrix4fv(modelViewMatrixLoc, false, flatten(modelViewMatrix));

gl.uniformMatrix4fv(projectionMatrixLoc, false, flatten(projectionMatrix));

gl.drawArrays(gl.TRIANGLES, 0, numPositions);

requestAnimationFrame(render);
