Camera that uses orthographic projection.

In this projection mode, an object's size in the rendered image stays constant regardless of its distance from the camera.

This can be useful for rendering 2D scenes and UI elements, amongst other things.

Code Example

const camera = new v3d.OrthographicCamera(width / - 2, width / 2, height / 2, height / - 2, 1, 1000); scene.add(camera);

OrthographicCamera(left : Number, right : Number, top : Number, bottom : Number, near : Number, far : Number)

left — Camera frustum left plane.
right — Camera frustum right plane.
top — Camera frustum top plane.
bottom — Camera frustum bottom plane.
near — Camera frustum near plane.
far — Camera frustum far plane.

Together these define the camera's viewing frustum.


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.

.bottom : Float

Camera frustum bottom plane.

.far : Float

Camera frustum far plane. Default is 2000.

Must be greater than the current value of near plane.

.left : Float

Camera frustum left plane.

.near : Float

Camera frustum near plane. Default is 0.1.

The valid range is between 0 and the current value of the far plane. Note that, unlike for the PerspectiveCamera, 0 is a valid value for an OrthographicCamera's near plane.

.right : Float

Camera frustum right plane.

.top : Float

Camera frustum top plane.

.view : Object

Set by setViewOffset. Default is null.

.zoom : number

Gets or sets the zoom factor of the camera. Default is 1.


See the base Camera class for common methods.

.setViewOffset (fullWidth : Float, fullHeight : Float, x : Float, y : Float, width : Float, height : Float) : null

fullWidth — full width of multiview setup
fullHeight — full height of multiview setup
x — horizontal offset of subcamera
y — vertical offset of subcamera
width — width of subcamera
height — height of subcamera

Sets an offset in a larger viewing frustum. This is useful for multi-window or multi-monitor/multi-machine setups. For an example on how to use it see PerspectiveCamera.

.clearViewOffset () : null

Removes any offset set by the .setViewOffset method.

.updateProjectionMatrix () : null

Updates the camera projection matrix. Must be called after any change of parameters.

.toJSON (meta : Object) : Object

meta -- object containing metadata such as textures or images in objects' descendants.
Convert the camera to Verge3D JSON Object/Scene format.
