$triregionnumber

The number of regions that is in the triangular shape.

Example

$triregionnumber
2

This means that there are two triangular regions. This command must be set after the command $ranges. The "triregionnumber" must be smaller than the "range number".

This command needs to be set before the command before the commands $triregiontype, $triranges,

For example:

$triregionnumber
2

$triregiontype
@type @periodnumber @period_spacing
@type @periodnumber @period_spacing

$triranges
@f1 @f2 @f3 @f4 @f5 @f6
@f1 @f2 @f3 @f4 @f5 @f6

@f1 @f2 @f3 @f4 @f5 @f6 are defined below according to its type For the @type, it is the same definition as type in $emptyperiodshape, see below For @periodnumber, it is repeating how many times For the @period_spacing, it is defining the spacing of each repeating objects.

Example of @type

@type.1~4 are triangle, circle, ellipse and rectangle.

@type = 1 is triangle. If it have n-trianges, it it repeating along x direction.
@type = 11 is triangle. If it have n-trianges, it it repeating along y direction.
@type = 2 is circle. If it have n-circles, it it repeating along x direction.
@type = 21 is circle. If it have n-circles, it it repeating along y direction.
@type = 3 is ellipse. If it have n-ellipses, it it repeating along x direction.
@type = 31 is ellipse. If it have n-ellipses, it it repeating along y direction.
@type = 4 is rectangle. If it have n-rectangle, it it repeating along x direction.
@type = 41 is rectangle. If it have n-rectangle, it it repeating along y direction.

If the parameters are not show in the figure, you should set those parameters as 0.

Type5~8 are sine shape period structure.

Type.5 and 6 can be determined by this expression:

$f_6<y<f_{1}sin{f}_{2}x+f_3;$

$f_4<x<f_5$

Type.7 and 8 can be determined by this expression:

$f_6<x<f_{1}sin{f}_{2}y+f_3;$

$f_4<y<f_5$
