■ User-defined ID: Displays the user ID for the object.
■ Blending: Specifies how to combine the filtered texture color with the
incoming fragment color in a texturing unit. This is equivalent to the
texture environment mode in OpenGL. Options are Add, Blend, Decal,
Modulate, and Replace.
■ WrappingS and WrappingT: The Repeat and Clamp texture wrapping
modes define the treatment of coordinate values that are outside the [0,1]
range.
■ Level Filter: Sets the texture filtering. Options are Nearest, Linear, and Base
Level.
■ Image Filter: Sets the image filtering. Options are Nearest, Linear, and Base
Level.
World
World is a special 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: Shows the object size with sub-objects.
■ User-defined ID: Displays the user ID for the object.
■ Enable Rendering: Sets the picking enable flag of this node. The effective
rendering enable status for this node is the logical AND of the enable flags
on this node and all of its ancestors. This means that the World node is
disabled if any of its ancestors are disabled. The status of the World node
has an effect only if all its ancestors are enabled. If the effective status is
set to True, this node is enabled. If it is False, it is disabled.
■ Enable Picking: Sets the picking enable flag of this node. The effective
rendering enable status for this node is the logical AND of the enable flags
on this node and all of its ancestors. This means that the World node is
disabled if any of its ancestors are disabled. The status of the World node
has an effect only if all its ancestors are enabled. Options are True and
False.
■ Alpha Factor: Allows groups of mesh objects to fade in and out
conveniently, provided that certain preconditions related to their
appearance are met. The Alpha Factor is defined for each node, and its
value is between 0 and 255.
