Camera frustum aspect ratio, window width divided by window height.

Camera frustum far plane.

Camera frustum vertical field of view, from bottom to top of view, in degrees.

Camera frustum near plane.

Sets an offset in a larger frustum. This is useful for multi-window or multi-monitor/multi-machine setups. For example, if you have 3x2 monitors and each monitor is 1920x1080 and the monitors are in grid like this:

+---+---+---+ | A | B | C | +---+---+---+ | D | E | F | +---+---+---+

then for each monitor you would call it like this:

const w = 1920; const h = 1080; const fullWidth = w * 3; const fullHeight = h * 2;

// A camera.setViewOffset( fullWidth, fullHeight, w * 0, h * 0, w, h ); // B camera.setViewOffset( fullWidth, fullHeight, w * 1, h * 0, w, h ); // C camera.setViewOffset( fullWidth, fullHeight, w * 2, h * 0, w, h ); // D camera.setViewOffset( fullWidth, fullHeight, w * 0, h * 1, w, h ); // E camera.setViewOffset( fullWidth, fullHeight, w * 1, h * 1, w, h ); // F camera.setViewOffset( fullWidth, fullHeight, w * 2, h * 1, w, h ); Note there is no reason monitors have to be the same size or in a grid.

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