# 20 degree tilted square polygon, 1x1 samp/pix
# Looks jaggy
load samp_1x1_20deg.pix a1

# 20 degree tilt, 3x3 regular
# Looks good
load samp_3x3_20deg.pix b1

# 20 degree tilt, 5x5 regular
# Only slightly better
load samp_5x5_20deg.pix c1

# 2 degree tilt, 1x1
# Looks jaggy
load samp_1x1.pix a2	

# 2 degree tilt, 3x3 regular
# At this tilt, acts almost like only 2 samples/pixel
load samp_3x3reg.pix b2	

# 2 degree tilt, 5x5 regular
# Looks good, but only like 4 samples/pixel, not 4x4
load samp_5x5reg.pix c2	

# 2 degree tilt, 2x2 jittered
# Looks like 4 samples/pixel, but noisy
load samp_2x2jit.pix b3	

# 2 degree tilt, 4x4 jittered
# Looks even better, like 16 samples/pixel
load samp_4x4jit.pix c3	

load samp_post_4.pix b4	
# 2 degree tilt, 1x1, postfiltered w. Gaussian
# Sigma = 0.4 x (filter_scale=4.0) / 2 = 0.8
# Blurry jaggies, just as you would expect

load samp_post_8.pix c4	
# 2 degree tilt, 1x1, postfiltered w. Gaussian
# Sigma = 0.4 x (filter_scale=8.0) / 2 = 1.6
# Blurrier jaggies
