Name	camera()
Examples	size(100, 100, P3D); noFill(); background(204); camera(70.0, 35.0, 120.0, 50.0, 50.0, 0.0, 0.0, 1.0, 0.0); translate(50, 50, 0); rotateX(-PI/6); rotateY(PI/3); box(45);
Description	Sets the position of the camera through setting the eye position, the center of the scene, and which axis is facing upward. Moving the eye position and the direction it is pointing (the center of the scene) allows the images to be seen from different angles. The version without any parameters sets the camera to the default position, pointing to the center of the display window with the Y axis as up. The default values are camera(width/2.0, height/2.0, (height/2.0) / tan(PI*30.0 / 180.0), width/2.0, height/2.0, 0, 0, 1, 0). This function is similar to gluLookAt() in OpenGL, but it first clears the current camera settings.
Syntax	camera() camera(eyeX, eyeY, eyeZ, centerX, centerY, centerZ, upX, upY, upZ)
Parameters	eyeX float: x-coordinate for the eye eyeY float: y-coordinate for the eye eyeZ float: z-coordinate for the eye centerX float: x-coordinate for the center of the scene centerY float: y-coordinate for the center of the scene centerZ float: z-coordinate for the center of the scene upX float: usually 0.0, 1.0, or -1.0 upY float: usually 0.0, 1.0, or -1.0 upZ float: usually 0.0, 1.0, or -1.0
Returns	void
