Examples

Ex.1: Volumetric calculation

# Calculate volume of a grid down to a level
set level 2500               ;# Set the level
z                            ;# Erase screen
win demo                     ;# Get demo window (450000 460000 6450000 6460000 1000 4000)
spe bgc whi                  ;# Specify background color to white
mak ran 5                    ;# Make random points
mhi pp                       ;# Save data

ewi 30                       ;# Expand window 30%
mak ran 22 z 4500 5000       ;# Make randowm values within z range
ret 4                        ;# Return window
eli iwi                      ;# Eliminates inside window
mlo pp app                   ;# Append with saved data
# The dataset will now most likely have a dome structure
grp inc 100 100              ;# Make grid with increment 100 x 100
mhi mygrid                   ;# Move the grid to workspace
eli gt $level                ;# Eliminate greater than level
sub $level                   ;# Subtract to zero level
mul -1                       ;# Multiply with -1
und 0                        ;# Set undefined values to 1
vol                          ;# Calculate volume
mak p                        ;# Make polygrid
mhi volgrid                  ;# Save in workspace
mlo mygrid                   ;# Get structure grid
mak p                        ;# Make polygrid
mak rsc volgrid              ;# Replace scalars from volgrid 
map                          ;# Map the grid with volume on top
con n 11                     ;# Contour 11 levels
pla z $level                 ;# Draw a plane at level
acp * opa 0.4                ;# use opacity
tx2 lle col bla txt "Z::$level Vol: [gvar volume]" ;# Text with volume number
cco rev s 0 500 3000 tit "Volume" ;# Display color legend
