Spherical Camera 球形照相机

A spherical camera can capture a 360-degree panorama. The produced images are called 'latitude-longitude' images (often abbreviated as 'latlong') and can be used as environment maps or as a dome light texture.

球形照相机可以捕捉到360度的全景。产生的图像被称为“经纬度”图像(通常缩写为“ latlong”) ，可用作环境地图或作为一个圆屋顶光纹理。

Parameters

参数

The spherical camera has no options of its own. The main camera's FOV is ignored but its aspect ratio is used to allow for fine-tuning the effect, if necessary. A spherical camera always captures an image with 360 degrees of horizontal FOV and 180 degrees of vertical FOV. For this reason, it is recommended that the rendered image size has a 2:1 aspect ratio. The recommended camera aspect ratio is 1.0.

球形照相机没有自己的选择。主相机的视场被忽略，但它的长宽比是用来微调的效果，如果必要的。球面相机总是能捕捉到360度水平视场和180度垂直视场的图像。由于这个原因，建议渲染图像的大小应该是2:1的纵横比。推荐的相机长宽比是1.0。

To demonstrate the effect of the spherical camera, we'll use the following reference scene. The camera is pointing towards the green sphere. The red sphere is 90 degrees to the left of the camera and the blue sphere is 90 degrees to the right. The black sphere is exactly behind the camera.

为了演示球形相机的效果，我们将使用下面的参考场景。照相机正对着那个绿色的球体。红色的球体在照相机左侧90度，蓝色的球体在右侧90度。黑色的球体正好在照相机的后面。

Below we demonstrate the spherical camera on 2:1 pixel ratio image. As it can be seen, it captures a full 360 degree panorama around the camera.

下面我们演示了2:1像素比例的球形相机图像。正如它可以看到的，它捕获了一个完整的360度全景照相机周围。
