View source for VVIEW2D: Switches of the Program VVIEW2D

[[de: VVIEW2D: Schalter des Programmes VVIEW2D]]
Within the program VVIEW2D some parameters can be modified at different levels. The user of the program can modify the appearance of the representation of the data using different switches interactively. These switches can only have the values ON/OFF (+/-). Arrangement, tagging and significance are briefly explained in the following:

* working level LEVEL_2
:* '''OvlGrd''': superpose grid / do not superpose grid
:* '''ProfTx''': display labelled locations / do not display labelled locations
: Notice: the result can be influenced through a file of type [[GPROFIL.DAT|gprofil.dat]]
:* '''InsBau''': read structural informations from [[INSEL.DAT|insel.dat]] / do not read
: Notice: not realized at the moment
:* '''BodPol''': display bottom polygon / do not display bottom polygon
:* '''StLogo''': display company logo / do not display company logo
:* '''HScale''': display scale / do not display scale
:* '''OflPol''': display surface polygon / do not display surface polygon
:* '''MitVek''': display superimposed vectors / do not display superimposed vectors when vector quantities are plotted (works in combination with switch '''OvlVek''' on level 3) 
* working level LEVEL_3
:* '''FFlGra''': use [[VVIEW2D: Demo Examples: Coloured Isosurface Representation|coloured isosurface representation]] / use isoline representation
:* '''FillAr''': fill polygons with colour / fill polygons with coloured pixels
:* '''zIsDat''': show additional data-isolines / do not show additional data-isolines
:* '''NoSel''': out of function
:* '''BIsDat''': label data-isolines / do not label data-isolines
: Notice: labelling isolines is time consuming for large grids
:* '''NoSel''': out of function
:* '''OvlVek''': [[VVIEW2D: Demo Examples: Coloured Isosurface Representation#Orthogonal Velocity 1|coloured isosurface representation]] with superimposed vector arrows/circles of constant length/diameter / [[VVIEW2D: Demo Examples: Vector Representation#Orthogonal Velocity 1|vector representation]] with vector arrows/circles of constant or variable length/diameter; when superimposed vector arrows of constant length are plotted then also switch '''MitVek''' of level 2 will influence the contents of the resulting scene
:* '''PrpVek''': length and width of vector arrows or diameter of vector circles is proportional to the value of the vector quantity / length and width of vector arrows or diameter of vector circles is constant
:* '''ScrfON''': generate [[VVIEW2D: Demo Examples: Hatching Representation|hatching representation]] / do not generate hatching representation
: Notice: switch '''FFlGra''' must be ON in this case
:* '''ScrfFF''': in case of hatching representation, a background coloured isosurface representation is generated / not generated
:* '''ScrfPM''': in case of hatching representation, only two different hachures are used to show areas with positive and negative values of the data / many hachures are used
:* '''IsoChH''': character height for labelled contour lines can be not modified manually / may be modified manually during program execution
:* '''IsoBox''': a box is drawn / not drawn around the labels of the contour lines. 
* working level LEVEL_4
:* '''ReRLgt''': read the contents of the file [[LIGHTS.DAT|lights.dat]] before generating a picture / do not read
:* '''MetaFi''': write graphical information to a plot metafile / do not write
:* '''NoStop''': all selected time steps of synoptic data are displayed one after the other in non stop mode / stop for user interaction after each figure
:* '''ProjBe''': [[VVIEW2D: Demo Examples: Coloured Isosurface Representation#Orthogonal Velocity 2|coloured isosurface representation]] filled with colour corresponding to the value of the displayed component]] of the vector / [[VVIEW2D: Demo Examples: Coloured Isosurface Representation#Orthogonal Velocity 1|coloured isosurface representation filled with colour corresponding to the value of the overall vector]]
:* '''ProjOr''': display [[VVIEW2D: Demo Examples: Vector Representation#Orthogonal Velocity 1|orthogonal component of the vector]] / dipsplay [[VVIEW2D: Demo Examples: Vector Representation#Parallel Velocity 1|parallel component of the vector]]
:* '''HollowArr''': superimposed vector arrows for the parallel component are not filled with constant colour above a before displayed scalar quantity
:* '''NoSel''': out of function
:* '''ZusTxT''': additional comment lines which are stored in a file of type [[LAYOUT.DAT|layout.dat]] are displayed in the figure / not displayed
