DME
Operations
Setting lights
Light source types
The following type of light sources are available (see
figure).
Parallel: Parallel light source
Point: Point light source. As the light source is placed
further away, the illuminated range becomes wider
and the light becomes weaker.
Line: Line light source
Whole: Non-directional light source which illuminates the
whole image.
Spotlight
Image before movement
Light source
Light source
Coordinate axis = Source
Spotlight moves together
with DME image.
Coordinate axis = Target
Spotlight does not move,
even if DME image moves.
Parallel Point
Light source
Selecting the lighted area
You can select the area lit by the spotlight.
FRGD: The light strikes the image foreground.
BKGD: The light strikes the image background.
Both: The light strikes both foreground and background.
Line Whole
Linking and unlinking image and spotlight
The spotlight can move together with a DME image, or be
fixed in place.
Source: Place the light source in source coordinate space.
The spotlight is linked and moves when the image
moves.
Target: Place the light source in target coordinate space.
The spotlight does not move, even when the image
moves.
Background
No effect

Surface Flat
For the currently selected light source only, you can
forcibly make the image surface effect flat.
This is effective when you have selected texture as image
surface effect and want a flat effect for one light source
only.
Light shape
Creates the light shape.
•
Select the shape pattern
For shape patterns, see “Shape Patterns” (page 409).
•
Set the size, degree of deformation, softness, and
