lookat-camera

Simple "lookat" camera abstraction built on top of gl-matrix.

Usage

See demo.js for a usage example.

camera = require('lookat-camera')()

Creates a new camera instance.

view = camera.view([view])

Updates the view matrix based on the camera's current configuration and returns the result. Optionally, you may pass in your own view array to modify directly.

camera.position

[x, y, z] vector that determines the position of the camera in world space.

camera.target

[x, y, z] vector that determines the target of the camera in world space.

camera.up

Normalized [x, y, z] vector that determines the up direction of the camera. Generally you'll want this to be [1, 0, 0], [0, 1, 0] or [0, 0, 1].
