Point and Line options

As points and lines can be viewed, there are several interesting options for each of them.

Menu: Options->Geometry->Point options...

Point options:

Point options window

Here you can select whether to draw the points Quick, Nice or with the center of a Texture glued to the point. Quick: points will be drawn as big dots. Nice: points will be drawn as little spheres (quadrilateral meshes). For every draw style, the Point Size can be changed, but ranges vary between Quick, which depends on the graphics library, and Nice and Texture. When the Nice style is selected, the Nice detail level can be adjusted. The number represents the number of vertical and horizontal subdivisions of a sphere.

Note: The changes affect the representation of all the points - point elements and the arrow heads of vectors when using the Point detail level (see Display vectors ).

Menu: Options->Geometry->Line options...

Line options window

Here you can select whether to draw the lines with a Quick style or a Nice one. Selecting a Line Size of 0.0 in the Nice style, will cause the lines not to be drawn. Quick: lines are drawn as 3-point thick lines. The line size is fixed. Nice: lines are drawn as long 4-sided or 8-sided prisms. The size and width of the lines can be changed. When the lines are drawn nicely, the number of sides of the prism used to draw them can be changed between 4 and 8 sides.

Note: Line options no longer affect the stream lines as before, but only the line elements. For stream lines options see Stream Lines .
