Class diagram for cameras

Description

Perspective Camera

A camera of class PerspectiveCamera emulates the human eye: objects farther away appear smaller in size. Perspective camera projections are natural in situations where you want to imitate how objects appear to a human observer.

PerspectiveCamera camera = new PerspectiveCamera( 
        45,             // vertical field of view
        width / height, // aspect ratio
        1,              // near plane
        1000 );         // far plane

Orthographic Camera

In contrast to perspective cameras, cameras of class OrthographicCamera produce parallel projections, with no distortions for distance. Orthographic cameras are useful for precise design work, where visual distortions would interfere with exact measurement.

// Simple creation in Parallax 1.3
OrthographicCamera camera = new OrthographicCamera( 
        width,  // width plane
        height, // height plane
        1,      // near plane
        1000 ); // far plane

// Complex creation
OrthographicCamera camera = new OrthographicCamera( 
        width / - 2,  // left
        width / 2,    // right
        height / 2,   // top
        height / - 2, // bottom
        1,            // near
        1000 );       // far

Cube Camera

Cube camera used for rendering cube maps.

// Simple example how to use the camera
CubeCamera cubeCamera = new CubeCamera( 
        1,     // near
        1000,  // far
        256 ); // cube resolution
cubeCamera.getRenderTarget().setMinFilter( TextureMinFilter.LINEAR_MIPMAP_LINEAR );
getScene().add( cubeCamera );

MeshBasicMaterial material = new MeshBasicMaterial(); 
material.setEnvMap( cubeCamera.getRenderTarget() );
