Class LwoTexture

java.lang.Object

com.sun.j3d.loaders.lw3d.ParserObject

com.sun.j3d.loaders.lw3d.LwoTexture

 class LwoTexture
extends ParserObject

This class is responsible for parsing the binary data in an Object file that describes a texture for a particular surface and turning that data into Java3D texture data. If the texture is coming from a file (which is the only type of texture handled by the loader currently; other types of texture definitions are ignored), then this class instantiates a TargaReader object to read the data in that file. Once all of the data has been read, the class creates a Java3D Texture object by first scaling the image using the ImageScaler class (since all textures must have width/height = power of 2; Note: this functionality is now built into the TextureLoader class, so it could be removed from this loader) and then creating a Texture with that image.

          int length,
          java.lang.String typename,
          int debugVals)
     throws java.io.FileNotFoundException

isHandled

boolean isHandled()

The loader currently only handles CTEX and DTEX texture types (These either represent the surface color like a decal (CTEX) or modify the diffuse color (DTEX)

getTexture

Texture getTexture()

Return the actual Texture object associated with the current image. If we've already created a texture for this image, return that; otherwise create a new Texture

getType

readTexture

void readTexture(int length)
           throws java.io.FileNotFoundException,
                  ParsingErrorException

Parse the binary file to retrieve all texture parameters for this surface. If/when we encounter a TIMG parameter, which contains the filename of an image, then create a new TargaReader object to read that image file

Throws:

java.io.FileNotFoundException

ParsingErrorException
