PLSCMAP1LA(3plplot)						    PLplot API						       PLSCMAP1LA(3plplot)

NAME

       plscmap1la - Set color map1 colors using a piece-wise linear relationship

SYNOPSIS

       plscmap1la(itype, npts, pos, coord1, coord2, coord3, coord4, rev)

DESCRIPTION

       This  is a version of plscmap1l(3plplot) that supports alpha transparency. It sets color map1 colors using a piece-wise linear relationship
       between position in the color map (from 0 to 1) and position in HLS or RGB color space (see the PLplot documentation) with alpha value (0.0
       - 1.0). It may be called at any time.

       This function is used in example 30.

ARGUMENTS

       itype (PLBOOL, input)
	      true: RGB, false: HLS.

       npts (PLINT, input)
	      number of control points

       pos (PLFLT *, input)
	      position for each control point (between 0.0 and 1.0, in ascending order)

       coord1 (PLFLT *, input)
	      first coordinate (H or R) for each control point

       coord2 (PLFLT *, input)
	      second coordinate (L or G) for each control point

       coord3 (PLFLT *, input)
	      third coordinate (S or B) for each control point

       coord4 (PLFLT *, input)
	      fourth coordinate, the alpha value for each control point

       rev (PLBOOL: *, input)
	      reverse flag for each control point. (rev[i] refers to the interpolation interval between the i and i + 1 control points).

NAME

       plfill3 - Draw filled polygon in 3D

SYNOPSIS

       plfill3(n, x, y, z)

DESCRIPTION

       Fills the 3D polygon defined by the n points in the x, y, and z arrays using the pattern defined by plpsty(3plplot) or plpat(3plplot).  The
       routine will automatically close the polygon between the last and first vertices.  If multiple closed polygons are passed in x,	y,  and  z
       then plfill3(3plplot) will fill in between them.

       Redacted form:  General: plfill3(x, y, z) Perl/PDL: plfill3(n, x, y, z)

       This function is used in example 15.

ARGUMENTS

       n (PLINT, input)
	      Number of vertices in polygon.

       x (PLFLT *, input)
	      Pointer to array with x coordinates of vertices.

       y (PLFLT *, input)
	      Pointer to array with y coordinates of vertices.

       z (PLFLT *, input)
	      Pointer to array with z coordinates of vertices.
