v1.3 beta1 of Java3D OpenGL version support this
(No support in DirectX version) if it detects that
OpenGL v1.2 is used and extension support.
See doc in Texture
public void setMinimumLOD(float minimumLod)
public void setMaximumLOD(float maximumLod)
public void setMaximumLevel(int maximumLevel)
public void setBaseLevel(int baseLevel)
public void setLodOffset(float s, float t, float r)
Thanks.
