Method Detail
setLens(focalLength, frameHeight)
Uses Focal Length (in mm) to estimate and set FOV
35mm (fullframe) camera is used if frame size is not specified;
Formula based on http://www.bobatkins.com/photography/technical/field_of_view.html
- Parameters:
- focalLength
- frameHeight
setViewOffset(fullWidth, fullHeight, x, y, width, height)
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
var w = 1920;
var h = 1080;
var fullWidth = w * 3;
var fullHeight = h * 2;
--A--
camera.setOffset( fullWidth, fullHeight, w * 0, h * 0, w, h );
--B--
camera.setOffset( fullWidth, fullHeight, w * 1, h * 0, w, h );
--C--
camera.setOffset( fullWidth, fullHeight, w * 2, h * 0, w, h );
--D--
camera.setOffset( fullWidth, fullHeight, w * 0, h * 1, w, h );
--E--
camera.setOffset( fullWidth, fullHeight, w * 1, h * 1, w, h );
--F--
camera.setOffset( fullWidth, fullHeight, w * 2, h * 1, w, h );
Note there is no reason monitors have to be the same size or in a grid.
- Parameters:
- fullWidth
- fullHeight
- x
- y
- width
- height
