# this illustrates how to draw a sphere using HoloDraw

# the X and Y values are degrees around the sphere
# and the Z value is the sphere's radius

# let's make some East-West lines in blue
color=0 0 1

# draw a line around the sphere's equator
# X will go from 0 to 360 degrees
# Y will be 0 since this is the equator
# Z will be 5000, the radius of our sphere
line: 0 0 5000, 360 0 5000

# how about another line at Y=+45 and Y=-45
line: 0 45 5000, 360 45 5000
line: 0 -45 5000, 360 -45 5000

# next, our North-South lines should be green
color=0 1 0

# draw a line from North pole (90 degrees) to South pole (-90) at X=0 
line: 0 90 5000, 0 -90 5000
# and again halfway around the sphere, at X=180
line: 180 90 5000, 180 -90 5000

# while we're at it, make more vertical lines every 30 degrees
line: 30 90 5000, 30 -90 5000
line: 60 90 5000, 60 -90 5000
line: 90 90 5000, 90 -90 5000
line: 120 90 5000, 120 -90 5000
line: 150 90 5000, 150 -90 5000

# and on past the 180 degree line we already drew
line: 210 90 5000, 210 -90 5000
line: 240 90 5000, 240 -90 5000
line: 270 90 5000, 270 -90 5000
line: 300 90 5000, 300 -90 5000
line: 330 90 5000, 330 -90 5000

# don't need a line at 360 degrees because that is the same as 0 degrees
