Gets the definition of a specified rendering style (for use with selected TDPACK routines).

Available in version 4.3.1 and later.


	procedure tdgtrs (
		render_index    [1] : integer,  
		bot_fill_index1 [1] : integer,  
		bot_fill_index2 [1] : integer,  
		top_fill_index1 [1] : integer,  
		top_fill_index2 [1] : integer,  
		bot_line_index  [1] : integer,  
		top_line_index  [1] : integer,  
		draw_edge       [1] : integer,  
		udist           [1] : float,    
		vdist           [1] : float,    
		wdist           [1] : float     



An input integer scalar specifying the index of the rendering style to be retrieved. See the low-level "Rendering-Style Arrays" section for descriptions of the internal parameters defining the rendering styles.


Color indices (output) that will contain a range of colors used for the "bottom" side of a surface (where function values are less than the value on the surface).


Color indices (output) that will contain a range of colors used for the "top" side of a surface (where function values are greater than the value on the surface).


Color indices (output) that will contain colors used for lines drawn on the "bottom" or "top" side of a surface. If either one is set to a negative value, the drawing of those lines is turned off.


An integer scalar (output) that will contain a flag that indicates whether the edges of the individual triangles will be drawn.


Float scalars (output) that will contain the distances between slices in the U, V, and W directions, respectively.


This routine is part of the low-level TDPACK package, which is a group of Fortran and C callable routines for projecting objects from a 3-dimensional coordinate system having U, V, and W axes to a 2-dimensional projection plane having X and Y axes and/or for drawing the projections of those objects. This can be referred to somewhat loosely as "drawing objects in three dimensions".

Please see the documentation on TDGTRS for a full description of this procedure.
