Three.js中的相机参数 [英] Camera arguments in Three.js

问题描述

这是实例化相机的方式：

This is how a camera is instantiated:

var camera = new THREE.PerspectiveCamera(
    VIEW_ANGLE,
    ASPECT,
    NEAR,
    FAR
);

这些值是什么意思？

推荐答案

第一个参数是FOV，它表示视野，想象一下三脚架上的相机，如果将镜头换成广角，则FOV会更高。试想像一下，一个圆锥形从相机中出来，它只能看到该区域中的物体。

The first param is FOV means field of view, imagine a camera on a tripod, if you change lens to wide angle you get a higher FOV. Try to imagine a cone coming out from the camera, it can only see objects in that area.

ASPECT表示宽高比，宽屏电视是16/9，旧的是4/3，通常只要给它一个屏幕宽度/高度或您想要three.js使用的DIV的暗度即可。

ASPECT means aspect ratio, a widescreen TV is 16/9 and old ones were 4/3, usually just give it the screen width/height or the dims of a DIV you would like three.js to use.
