COMPONENT Texturing:3

# Test of multitexturing MODULATE and ADD modes used together.
# It shows that the order of operations matters (for some cases).
#
# From left to right:
# 1. yellowish material * squirrel texture
# 2. yellowish material * bricks texture
# 3. yellowish material * squirrel texture + bricks texture
# 4. yellowish material * bricks texture   + squirrel texture
#
# Notice how 3. and 4. are different --- order matters!
#
# "yellowish material" above means actually
# "X3D yellowish material combined with lighting".

# A nice test is to disable headlight (Ctrl + H in view3dscene).
# If the X3D implementation calculates the lighting before texturing
# (which is always true for Gouraud shading), then turning headlight off
# should make the lighting result black, which should result in:
#
# From left to right:
# 1. black
# 2. black
# 3. black + bricks texture   = just bricks texture
# 4. black + squirrel texture = just squirrel texture
# NavigationInfo { headlight FALSE }
