map - Map display

Name

map — Map display of dataset

Syntax

map [nor] [opa] [act] [mct | ctb] [sas | ups] [cel] [nrg] [flat] [dlev] [rng] [nrg] [liw] [drain] [rev] [all]

Description

Mapping scalar values onto the data geometry.

Arguments

No arguments. Map using the scalars to color the dataset.

nor

Use normal vectors to smooth the display. Takes more time.

opa opacity

To set opacity of an area. Values between 0 and 1.

act

Apply the active color table specified by the spe ctb ... command.

mct | ctb

Apply the menu color table specified by the spe ctb set ... command.

sas

Save scalar actor. A new scalar set can be immediately updated. See upd option.

upd

Will update the scalar actor made by map sas with the new scalar values.

cel

Map the cells in the dataset using cell scalars in coloring.

nrg

Use no regridding (no decimation) when mapping large grids. Only valid for grids because polydata will no be decimated.

flat [z_value]

Make a flat map at z_value, default 0.

dlev display_level

Apply display level in mapping, from 0 (no decimation) to 4 (high decimation and fast display for large grid).

rng range1 range2

Map the color table into the range area.

liw linewith

Map lines using linewith.

drain

Apply a color table usefull for drainage areas with good contrast between adjacent regions.

rev

Reverse the color table when mapping.

all

Will display all contours even when in 2D mode and the grid is outside the window. Default in 2D mode is that only the grid part that is inside the graphical window is mapped.

Examples

Ex.1: Map with color range

z                            ;# Erase screen
win demo                     ;# Get demo window (450000 460000 6450000 6460000 1000 4000)
spe bgc whi                  ;# Specify background color to white
mak ran 11                   ;# Make 11 random points
poi 2                        ;# Display points with size 2
grp inc 100 100              ;# Make grid with increment 100 x 100
map rng 2000 3000            ;# Map using range from 2000 to 3000
bol 2                        ;# Draw border lines
cco rev col bla s 2000 200 3000 tit "Range"  ;# Color legend

The above example produces this image.

Color range and legend

Ex.1: Map drainage area

z                            ;# Erase screen
win demo                     ;# Get demo window (450000 460000 6450000 6460000 1000 4000)
spe bgc whi                  ;# Specify background color to white
mak ran 22                   ;# Make 22 random points
grp inc 50 50                ;# Make grid with increment 50 x 50
oco frq 14 col bla liw 1     ;# Draw orthogonal contours 
oco dar                      ;# Generate default drainage areas
map drain                    ;# Map the drainage areas using a color table with good color contrast
