Texture Object Agents


A Texture Object Agent can be generated from the Surface Object Agent (using its getTexture() method). This Object Agent provides an interface to a texture assigned to a specific channel in a surface. Textures have their own settings, including one or more layers that accumulate to represent the visual makeup of the surface.


The following texture constants have been defined in LScript for use with the Texture Object Agent:

TXTRIMAGE                            Image Texture type

TXTRPROCEDURE                  Procedural Texture type

TXTRGRADIENT                      Gradient Texture type

Data Members

There are no Data Members currently exported by Texture Object Agents.


setChannelGroup(Channel Group Object Agent)
setChannelGroup(Channel Group Object Agent) sets the channel group for the Texture using the provided Object Agent. Envelopes created for parameters in the Texture's layers will belong to this group.

getChannelGroup( )
getChannelGroup() returns the Channel Group Object Agent for the Texture.

firstLayer( )
firstLayer() returns the TextureLayer Object Agent for the first layer defined in the Texture.

nextLayer(TextureLayer Object Agent)
nextLayer(TextureLayer Object Agent) returns the TextureLayer Object Agent that follows the specified TextureLayer for the Texture.

addLayer(layer type)
addLayer(layer type) creates a new layer in the Texture of the specific type—of TXTRIMAGE, TXTRPROCEDURE or TXTRGRADIENT—and returns the TextureLayer Object Agent for it.


This example demonstrates using the Texture Object Agent by adding a new Texture layer to an existing channel. You must load the "objects/geography/genearth/earth.lwo" object from the LightWave content into Layout for this example to work.
