param3d properties

description of the 3D curves entities properties

Description

The Param3d entity is a leaf of the graphics entities hierarchy.

visible:

This field contains the visible property value for the entity . It should be "on" or "off" . By default, the curves are visibles, the value's property is "on". If "off" the curves are not drawn on the screen.

data:

This field contains the coordinates of the 3d curves. it is the matrix [X,Y,Z] such as X(:,i), Y(:,i), Z(:,i) contain the 3D coordinates of the i'th curve. This field contains the default line_style property value for Segs, Arcs, Rectangle and Polyline objects.

line_mode:

This field contains the default line_mode property value for the polyline. Its value should be "on"(line drawn) or "off" (no line drawn).

line_style:

This field selects the type of line to be used to draw lines . Its value should be an integer in [1 6]. 1 stands for solid, the other values stand for a selection of dashes.

polyline_style:

This field selects the way curve are drawn: interpolated (default), staircase, barplot, arrowed and filled modes are available through integer index [1:5].

mark_mode:

This field contains the default mark_mode property value. Its value should be "on" or "off" (default value).

mark_style:

This field contains the default mark_style property value. The mark_style selects the type of mark to be displayed. Its value should be an integer in [0 9] which stands for: dot, plus, cross, star, filled diamond, diamond, triangle up, triangle down, trefle and circle. The figure below shows the aspects of the marks depending on the mark_style and the mark_foreground and mark_background properties.

mark_size_unit:

This field contains the default mark_size_unit property value. If mark_size_unit is set to "point", then the mark_size value is directly given in points. When mark_size_unit is set to "tabulated", mark_size is computed relative to the font size array: therefore, its value should be an integer in [0 5] whith stands for 8pt, 10pt, 12pt, 14pt, 18pt and 24pt. Note that param3d and pure scilab functions use tabulated mode as default ; when using plot function, the point mode is automatically enabled.

mark_size:

This field contains the default mark_size property value

. The mark_size selects the font size of the mark to be displayed. Its value should be an integer in [0 5] whith stands for 8pt, 10pt, 12pt, 14pt, 18pt and 24pt.

mark_foreground:

This field contains the mark_foreground property value which is the marks' edge color. Its value should be a color index (relative to the current color_map).

mark_background:

This field contains the mark_background property value which is the marks' face color. Its value should be a color index (relative to the current color_map).

thickness:

This field contains the default thickness value of the lines used to draw the axes and the curves. It should be a positive integer.

foreground:

This field contains the color index used to draw the curves. Its value should be a color index (relative to the current colormap).

clip_state:

This field contains the default clip_state property value. Its value should be :

  • "off" this means that all curves created after that are not clipped (default value).

  • "clipgrf" this means that all curves created after that are clipped outside the Axes boundaries.

  • "on" this means that all curves created after that are clipped outside the rectangle given by property clip_box.

clip_box:

This field contains the default clip_box property value. Its value should be an empty matrix if clip_state is "off". Other case the clipping is given by the vector [x,y,w,h] (upper-left point width height).

user_data:

This field can be use to store any scilab variable in the param3d data structure, and to retreive it.

parent:

This property contains the handle of the parent. The parent of the 3D curves entity should be of type "Axes" or "Compound".

Examples

a=get("current_axes");//get the handle of the newly created axes
t=[0:0.1:5*%pi]';
param3d1([sin(t),sin(2*t)],[cos(t),cos(2*t)],[t/10,sin(t)])

a.rotation_angles=[65,75]; 
a.data_bounds=[-1,-1,-1;1,1,2]; //boundaries given by data_bounds
a.thickness = 2;
h=a.children //get the handle of the param3d entity: an Compound composed of 2 curves
h.children(1).foreground = 3 // first curve
curve2 = h.children(2);
curve2.foreground = 6;
curve2.mark_style = 2;

History

ВерсияОписание
5.4.0 line_style value 0 is obsolete, use 1 instead (both are equivalent for SOLID). Using value 0 will produce an error in Scilab 5.4.1.
