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  : integer, bot_fill_index1  : integer, bot_fill_index2  : integer, top_fill_index1  : integer, top_fill_index2  : integer, bot_line_index  : integer, top_line_index  : integer, draw_edge  : integer, udist  : float, vdist  : float, wdist  : 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.bot_fill_index1
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.draw_edge
An integer scalar (output) that will contain a flag that indicates whether the edges of the individual triangles will be drawn.udist
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".
