PerspectiveCamera()
PerspectiveCamera(fov: Number, aspect: Number, near: Number, far: Number)
Creates a perspective camera.
Parameters
fov: Camera frustum vertical field of view.
aspect: Camera frustum aspect ratio.
near: Camera frustum near plane.
far: Camera frustum far plane.
Together these define the camera’s viewing frustum.
Properties
See the base Camera class for common properties.
Note that after making changes to most of these properties you will have to call .updateProjectionMatrix for the changes to take effect.
isPerspectiveCamera
.isPerspectiveCamera: Boolean
Read-only flag to check if a given object is of type PerspectiveCamera.
fov
.fov: Number
Camera frustum vertical field of view, from bottom to top of view, in degrees. Default is 50.
Readable and writable.
aspect
.aspect: Number
Camera frustum aspect ratio, usually the canvas width / canvas height. Default is 1 (square canvas).
Readable and writable.
near
.near: Number
Camera frustum near plane. Default is 0.1.
The valid range is greater than 0 and less than the current value of the far plane.
Readable and writable.
far
.far: Numbers
Camera frustum far plane. Default is 200.
Must be greater than the current value of near plane.
Readable and writable.
Methods
See the base Camera class for common methods.
updateProjectionMatrix()
.updateProjectionMatrix(): undefined
Updates the camera projection matrix. Must be called after any change of parameters.
