rotating an object

[Jerry]

Since spinning balls is so much fun,
Let's try spinning more than one.

from viz import *

go()

clearcolor(.8,.8,.8)
ball1 = add('ball.wrl')
ball1.translate(.3,1.8,1.5)
ball2 = add('ball.wrl')
ball2.translate(-.3,1.8,1.5)

balls = []
balls.append(ball1)
balls.append(ball2)

INCREMENT = .5

mouse(OFF)
restrictmouse(OFF)

def mousemove(x,y):					
	
	object = pick() 

	if viz.mouse.getState() == viz.MOUSEBUTTON_LEFT:
		mousedown = 1
	else:
		mousedown = 0
		
	if object in balls and mousedown == 1:
		object.rotate(0,1,0,-x*INCREMENT,RELATIVE_WORLD)
		object.rotate(1,0,0,y*INCREMENT,RELATIVE_WORLD)

		
mousedata(RELATIVE,RELATIVE)
callback(MOUSEMOVE_EVENT,mousemove)

Or if you like the number three,
Let's try to make them all agree.

from viz import *

go()

clearcolor(.8,.8,.8)
ball1 = add('ball.wrl')
ball1.translate(0,2.1,2)
ball2 = add('ball.wrl')
ball2.translate(.4,1.5,2)
ball3 = add('ball.wrl')
ball3.translate(-.4,1.5,2)

balls = []
balls.append(ball1)
balls.append(ball2)
balls.append(ball3)

INCREMENT = .5

mouse(OFF)
restrictmouse(OFF)

def mousemove(x,y):					
	
	object = pick() 

	if viz.mouse.getState() == viz.MOUSEBUTTON_LEFT:
		mousedown = 1
	else:
		mousedown = 0
		
	if object in balls and mousedown == 1:
		for b in range(len(balls)):
			balls[b].rotate(0,1,0,-x*INCREMENT,RELATIVE_WORLD)
			balls[b].rotate(1,0,0,y*INCREMENT,RELATIVE_WORLD)

		
mousedata(RELATIVE,RELATIVE)
callback(MOUSEMOVE_EVENT,mousemove)

And here's the one you want the most,
Just like iPhone make it coast.

from viz import *

go()

clearcolor(.8,.8,.8)
ball1 = add('ball.wrl')
ball1.translate(.3,1.8,1.5)
ball2 = add('ball.wrl')
ball2.translate(-.3,1.8,1.5)

balls = []
balls.append(ball1)
balls.append(ball2)

increment = .5
COAST = 1
mx = 0
my = 0
object = []
spinning = 0

mouse(OFF)
restrictmouse(OFF)

def mousemove(x,y):					
	global mx,my,object,spinning,increment
	
	if spinning == 0:
		object = pick() 

	if mouse.getState() == MOUSEBUTTON_LEFT:
		object = pick() 
		mousedown = 1
		killtimer(COAST)
		spinning = 0
	else:
		mousedown = 0
		
	if object in balls and mousedown == 1:
		object.rotate(0,1,0,-x*increment,RELATIVE_WORLD)
		object.rotate(1,0,0,y*increment,RELATIVE_WORLD)
		mx = x
		my = y

	if mousedown == 1 and spinning == 0:
		increment = .5
		spinning = 1
		starttimer(COAST,.01,FOREVER)
		
mousedata(RELATIVE,RELATIVE)
callback(MOUSEMOVE_EVENT,mousemove)

def onTimer(num):
	global spinning,mx,my,object,increment
	
	if num == COAST:
	
		object.rotate(0,1,0,-mx*increment,RELATIVE_WORLD)
		object.rotate(1,0,0,my*increment,RELATIVE_WORLD)

		increment = increment - .01
		if abs(increment) < .01:
			spinning = 0
			increment = .5
			killtimer(COAST)
						
viz.callback(viz.TIMER_EVENT,onTimer)
