问题描述
我注意到每个街景视图的视野(FOV)度在不同浏览器之间的缩放级别不同
我相信记录在FOV中的街景缩放级别
p> 0:180,1:90,2:45,3:22.5,4:11:25
我在街景全景中使用v3 Maps API,并在周围的镀铬区获取FOV的缩放级别。
0:127,1:90,2:53,3:28,4:14
在Firefox和IE6中,这些放大到FOV的视图与IE7和IE8中的相同:
>
0:180,1:90,2:45,3:22.5,4:11:25
- 是否记录在案?
- 如何执行街景FOV
在浏览器中保持一致或计算该缩放
等级的FOV值?
解决方案目前,有一个表将zoom和FOV关联起来:
0 => 180 1 => 90 2 => 45 3 => 22.5 4 => 11.5
您可以在JavaScript中将缩放转换为FOV,如下所示:
var fov = 180 / Math.pow(2,zoom);
I notice the Field of View (FOV) degree per street view zoom level is different between browsers
I believe the documented street view zoom level to FOV is
0: 180, 1: 90, 2: 45, 3: 22.5, 4: 11:25
I am using the v3 Maps API with street view panorama and get zoom levels to FOV in chrome around
0: 127, 1: 90, 2: 53, 3: 28, 4: 14
These zoom to FOV are the same in IE7 and IE8
in Firefox and IE6 they are:
0: 180, 1: 90, 2: 45, 3: 22.5, 4: 11:25
- Is this documented?
- How can I enforce the street view FOVconsistently across browsers or calculate the FOV value for that zoomlevel?
解决方案Currently, there is a table here relating zoom and FOV that says:
0=>180 1=>90 2=>45 3=>22.5 4=>11.5
You can convert from zoom to FOV in javascript like this:
var fov = 180 / Math.pow(2,zoom);
