ArcBall
ArcBall functionality for processing (ruby versions) as gem
Example Usage
The sketch class need to to inherit from PApplet to work and self should return such an instance. The following is a propane example. Drag mouse to rotate. Hold down 'x', 'y' or 'z' keys to constrain axis of rotation, mouse-wheel to zoom.
class ArcBallBox < Propane::App
############################
# Use mouse drag to rotate
# the arcball. Use mousewheel
# to zoom. Hold down x, y, z
# to constrain rotation axis.
############################
def setup
sketch_title 'Arcball Box'
Processing::ArcBall.init self, 300, 300
fill 180
end
def draw
background 50
box 300, 300, 300
end
def settings
size 600, 600, P3D
smooth 8
end
end
ArcBallBox.newSince version 0.0.2, you can also fix rotation to one axis at initialization
require 'arcball'
def setup
size(600, 600, P3D)
smooth(8)
Processing::ArcBall.constrain self #, :zaxis # default constrains to y-axis
fill 180
end
def draw
background(50)
box(300, 300, 300)
end
