writeLibe

public void writeLibe(GLMaterial[] mtls,
                      java.lang.String filename)

Write an array of GLMaterial objects to a .mtl file.

Parameters:

mtls - array of materials to write to file

filename - name of .mtl file

writeLibe

public void writeLibe(GLMaterial[] mtls,
                      java.io.PrintWriter out)

write

public void write(java.io.PrintWriter out,
                  GLMaterial mtl)

Write one material.

getClone

public GLMaterial getClone(GLMaterial mtl)

return a duplicate of this material. all values are duplicated except the texture, which is passed by reference to the clone (to prevent multiple copies of the same texture).

Returns:

the cloned material

find

public GLMaterial find(java.lang.String materialName)

find a material by name in an array of GLMaterial objects

findID

public int findID(java.lang.String materialName)

find a material by name in an array of GLMaterial objects return the array index of the material
