[Visualpython-users] controlling zooming

[jon s. <js...@so...>]

(Happy New Year!)

This program builds blocks out into space correctly, but it automatically
"zooms" way out (too far out) about midway through.

I can't figure out how to control this.

When I fiddle with scene.range, the image gets dim as if the lights have
been turned down.

I'd appreciate any ideas.


from visual import *
from time import sleep

pause=.2

c=[]
def init():
	for i in range(10):
		c.append((0,0,0))

	c[0]=[255,255,255]
	c[1]=[255,153,51]
	c[2]=[102,102,153]
	c[3]=[255,0,102]
	c[4]=[102,102,153]
	c[5]=[255,102,0]
	c[6]=[128,0,128]
	c[7]=[255,255,0]
	c[8]=[51,51,153]
	c[9]=[255,0,102]
	for each in c:
		for i in (0,1,2):
			each[i]=each[i]/255.
	scene.forward=[0.5,-0.5,-1]

init()

def tenblocks(firstblock=0):
	global pause
	for i in range(10):
		box(color=c[i],pos=(0,0,-firstblock + 10 -i))
		print scene.forward
		if pause>0.1:
			pause= pause * 0.99
			sleep(pause)

def ShowUpTo(Number=50):
	Tens=Number/10
	for i in range(Tens):
		tenblocks(firstblock=i*10)

ShowUpTo(Number=100)
