class  Texture1Dsegment  from  Graphic3d 
    
inherits  Texture1D  from  Graphic3d  

 
    ---Purpose:  This class provides the implementation
    -- of a 1D texture applyable along a segment.
    -- You might use the SetSegment() method
    -- to set the way the texture is "streched" on facets. 


uses

    StructureManager      from  Graphic3d 

is 
    Create(VM  :  StructureManager  from  Graphic3d; 
    	   FileName  :  CString  from  Standard)  returns  mutable  Texture1Dsegment  from  Graphic3d; 
    ---Purpose: Creates a texture from a file


    Create(VM  :  StructureManager  from  Graphic3d; 
    	   NOT  :  NameOfTexture1D  from  Graphic3d)  returns  mutable  Texture1Dsegment  from  Graphic3d;  
    ---Purpose: Creates a texture from a predefined texture name set.

	       X2,Y2,Z2  :  ShortReal  from  Standard);
    ---Purpose: Sets the texture application bounds. Defines the way
    -- the texture is stretched across facets.
    -- Default values are <0.0, 0.0, 0.0> , <0.0, 0.0, 1.0>
