<!-- Reflections
|
|
|
|
PARAMETERS: There are two forms of cube map texture:- vertical cross and 6 images.
|
|
Either can be used - alternative forms are shown in <parameters> and in <texture-unit>
|
|
|
|
The reflection is set proportional to the shininess of the material. Thus by
|
|
varying the material shininess value over or between objects the amount of
|
|
refection can be controlled. The overall amount of reflection may be
|
|
adjusted by the use of <refl_correction> -1.0 (fully transparent)- 1.0 (fully opaque).
|
|
|
|
The overall values of the coloured fringing or fresnel effect may be adjusted
|
|
by the use of <rainbowiness> and <fresneliness>.
|
|
|
|
If your result is too dark/too light the overall ambient light value can be adjusted
|
|
by the use of <ambient_correction>. This correction also takes out some of the blueness
|
|
added as default to compensate for the lack of reflection.
|
|
|
|
USE: To use the default reflection effect (controlled by material shininess values) use
|
|
|
|
<effect>
|
|
<inherits-from>Effects/reflect</inherits-from>
|
|
<object-name>Fuselage</object-name>
|
|
</<effect>
|
|
|
|
To use your own reflection effectuse
|
|
|
|
<effect>
|
|
<inherits-from>Aircraft/Lightning/Models/Effects/lightningreflect</inherits-from>
|
|
<object-name>Fuselage</object-name>
|
|
</<effect>
|
|
|
|
in your model file.
|
|
|
|
To use your own effect place your efffect file containing something like this:
|
|
|
|
<name>Effects/lightningreflect</name>
|
|
<inherits-from>Effects/reflect</inherits-from>
|
|
|
|
and the the modified tags in the path as above
|
|
|
|
EXAMPLES: You can find examples of both usages in the Hunter and Lightning models.
