lod (modifier)
Usage
member(whichCastmember).model(whichModel).lod.lodModifierProperty
Description
3D modifier; dynamically removes detail from models as they move away from the camera.
This modifier can only be added to models created outside of Director in 3D modeling programs.
The value of the
type property of the model resources used by these models is #fromFile. All
such models use detail reduction whether or not the
lod modifier is attached. Attaching the
modifier allows you to control the properties of detail reduction. The modifier cannot be added
to primitives created within Director.
The
lod modifier data is generated by 3D modeling programs for all models. Setting the
userData property "sw3d_no_lod = true" allows you to specify that the lod modifier data and
memory be released when streaming is complete.
Be careful when using the
sds and lod modifiers together, because they perform opposite
functions (the
sds modifier adds geometric detail and the lod modifier removes geometric
detail). Before adding the
sds modifier, it is recommended that you disable the lod.auto
modifier property and set the
lod.level modifier property to maximum resolution, as follows:
member("myMember").model("myModel").lod.auto = 0
member("myMember").model("myModel").lod.level = 100
member("myMember").model("myModel").addmodifier(#sds)
The lod modifier has the following properties:
• auto allows the modifier to set the level of detail reduction as the distance between the model
and the camera changes. The value of the modifier’s
level property is updated, but setting the
level property will have no effect when the auto property is set to TRUE.
• bias indicates how aggressively the modifier removes detail from the model when the
modifier’s
auto property is set to TRUE. The range for this property is from 0.0 (removes all
polygons) to 100.0 (removes no polygons). The default setting for this property is 100.0.
• level indicates the amount of detail reduction there will be when the modifier’s auto property
is set to
FALSE. The range of this property is 0.0 to 100.00.
Note: For more detailed information about these properties, see the individual property entries.
