Detailed Description

The type t_pattern contatins all the necessary information to apply a texture on a given shape's surface.

Parameters

has_pattern	Stores TRUE if shape has a pattern or FALSE, if not.
pattern_at	Receives a pattern function to apply the corresponding pattern. For more information, see t_pttr_at description.
texture_map	This structure creates a t_pattern subclass (the same as t_pttr_at, which calls stripe_at() or checkered_at()). t_text_map is a subclass that uses spherical_map(), planar_map() or cylindrical_map() to define how to apply a pattern on a given 2D or 3D shape's surface.
width	Receives u, the horizontal value of checkers squares.
height	Receives v, the vertical value of checkers squares.
a	Receives the first color of a given pattern to be applied.
b	Receives the second color of a given pattern to be applied.
transform	Stores matrix transformation so that pattern be manipulated.
