The JSR-184 data file is represented as the root
object of your scene. Many of the parameters of
objectsintheJSR-184datafilecanbeadjusted
to optimize the output of your scene. You can
preview your exported scene using the JSR-184
Standalone Player (page 3 –570).
Note: All editable parameters are displayed in italic.

Material Table
Material Table is a special object that contains all
the materials and textures used in the JSR- 184
scene. The Material Table has a two-level structure:
the 3ds Max material nam e is the first level and its
associated textures compr ise the second level. The
Material Table is represented as [Material Table] in
theJSR-184scenetree.
The3dsMaxleveldisplaysthefollowing
parameters:
• Approx.Object Size:Showstheobjectsizewith
sub-objects.
• User-defined ID:DisplaystheuserIDforthe
object.
• Layers: Sets the rendering layer for the JSR-184
Appearance Object. When rendering a World,
Group, or Mesh, submeshes and sprites are
rendered in the order of ascending layers.
The texture level displays the following par ameters:
• Approx.Object Size:Showstheobjectsizewith
sub-objects.
• User-defined ID:DisplaystheuserIDforthe
object.
• Blending:Specifieshowtocombinethefiltered
texture color with the incoming fragment
color in a texturing unit. This is equivalent to
the texture environment m ode in OpenGL.
Options are Add, Blend, Decal, Modulate, and
Replace.
• WrappingS and WrappingT:TheRepeatand

treatment of coordinate values that are outside

• Level Filter: Sets the texture filtering. Options
are Nearest, Linear, and Base Level.
• Image Filter:Setstheimagefiltering.Options
are Nearest, Linear, and Base Level.
World
World is a spec ial Group node that is a top-level
container for scene graphs. A World Object is
represented as <<World>> in the JSR-184 scene
tree. Every world object has three sub-objects:
[Background], [Active Camera], and [Ambient
Light]. A World object has the following
parameters:
• Approx.Object Size:Showstheobjectsizewith
sub-objects.
