krpano实践之全景图缩放，旋转，倾斜，自动旋转，VR，全屏方法

/*定义控件*/
var krpano = document.getElementById("krpanoSWFObject");
/*获取变量*/
var fov = Number(krpano.get("view.fov"));
var hlookat = Number(krpano.get("view.hlookat"));
var vlookat = Number(krpano.get("view.vlookat"));
/*放大*/
fov -= 10.0;
krpano.set("view.fov", fov);
/*缩小*/
fov += 10.0;
krpano.set("view.fov", fov);
/*左旋转*/
hlookat += 10.0;
krpano.set("view.hlookat", hlookat);
/*右旋转*/
hlookat -= 10.0;
krpano.set("view.hlookat", hlookat);
/*上倾斜*/
vlookat -= 10.0;
krpano.set("view.vlookat", vlookat);
/*下倾斜*/
vlookat += 10.0;
krpano.set("view.vlookat", vlookat);
/*自动旋转*/
krpano.set("autorotate.enabled", true);
/*VR模式*/
krpano.call("WebVR.enterVR();");
/*全屏*/
krpano.set("fullscreen", true);
/*停止旋转*/
krpano.set("autorotate.enabled", false);

以上的方法如放大缩小是不带动画的，有卡顿的感觉。下面的方法利用setTimeout方法实现平滑过渡。

/*放大*/
krpano.set("fov_moveforce",-1);
setTimeout("krpano.set('fov_moveforce',0)",200);
/*缩小*/
krpano.set("fov_moveforce",1);
setTimeout("krpano.set('fov_moveforce',0)",200);
/*左旋转*/
krpano.set("hlookat_moveforce",-1);
setTimeout("krpano.set('hlookat_moveforce',0)",200);
/*右旋转*/
krpano.set("hlookat_moveforce",1);
setTimeout("krpano.set('hlookat_moveforce',0)",200);
/*上倾斜*/
krpano.set("vlookat_moveforce",-1);
setTimeout("krpano.set('vlookat_moveforce',0)",200);
/*下倾斜*/
krpano.set("vlookat_moveforce",1);
setTimeout("krpano.set('vlookat_moveforce',0)",200);
