lod --- Level Of Detail display
...
Syntax for general commands
frustum
Create a polygonal model of the current view frustum in the active dataset.
automatic "on" | "off"
Turn the automatic level of detail level selection on and off.
epsilon value
Approximate error in number of pixels. This affects which version of the decimated dataset is selected for display. Only positive values are supported. The default value is 1.0. A lower epsilon value means that a finer resolution version of the dataset is used for display.
glreport
Prints information about the active opengl GPU in the Messages window.
glextensions
Prints information about the opengl extensions in the Messages window.

lod dis [showfullresmesh] [col] [alpha] |
Description
For displaying solid color grids.
Arguments
showfullresmesh
Show gridlines on the grids when the finest (the original) version of the data has been selected and is used for display.
col r g b
Specify the color to be used.
The RGB values should be between 0.0 and 1.0.
alpha a
Specify the alpha to be used.
The alpha value should be between 0.0 and 1.0.

lod poi [range] [zerocenter] [point_size] [contour_increment] [contour_values] [contour_aml] [color_filling_method] [solid_color] [show_all_points][field] |
Description
For displaying point cloud data.
Arguments
range min max
Specify data range to be used for color lookups. When not specified the range of the data is used.
zerocenter
Setting the data range to +- the maximum absoulute range of the dataset:
range_min = -max(abs(data_range_min), abs(data_range_max))
range_max = max(abs(data_range_min), abs(data_range_max))
point_size size
Size of the points to display. The default value is 1.0.
color_filling_method "solid" | "continous" | "discrete"
Specify the coloring method to be used for the grid surface.
"solid" - The same color everywhere. See the "solid_color" argument for how to specify the color.
"continous" - A color lookup table is used for coloring based on depth.
"discrete" - A single color is selected from the color lookup table for each region between the contour lines. The color is taken from the color lookup table.
contour_increment distance
Display evenly spaced color regions with distance in meters between regions.
contour_values num_values value1 .. value32
Explicitly specify the color regions.
num_values is an integer, valueXX are floats representing depth in meters.
contour_aml
Display color regions according to the Additional Military Layers specification:
For depths less than 100 meters the color regions are 5 meters tall.
For depths between 100 and 400 meters the color regions are 10 meters tall.
For depths greater than 400 meters the color regions are 20 meters tall.
solid_color r g b
Specify the color to be used with "solid" color display.
The RGB values should be between 0.0 and 1.0.
show_all_points
Always show all the points in the dataset.
field str
Use field data with given name for coloring.

lod map [range] [zerocenter] [showfullresmesh] [contour_increment] [contour_values] [contour_aml] [color_filling_method] [solid_color] [show_contour_lines] [contour_line_color] [textures] |
Description
For displaying grid data with color lookup table from height/depth, contour lines and projected images.
Arguments
range min max
Specify data range to be used for color lookups. When not specified the range of the data is used.
zerocenter
Setting the data range to +- the maximum absoulute range of the dataset:
range_min = -max(abs(data_range_min), abs(data_range_max))
range_max = max(abs(data_range_min), abs(data_range_max))
showfullresmesh
Show gridlines on the grids when the finest (the original) version of the data has been selected and is used for display.
contour_increment distance
Display evenly spaced contour lines with distance in meters between contour lines.
contour_values num_values value1 .. value32
Display a given number of contour values.
num_values is an integer, valueXX are floats representing depth.
contour_aml
Display contour lines according to the Additional Military Layers specification:
For depths less than 100 meters the distance between the contour lines is 5 meters.
For depths between 100 and 400 meters the distance between the contour lines is 10 meters.
For depths greater than 400 meters the distance between the contour lines is 20 meters.
color_filling_method "solid" | "continous" | "discrete"
Specify the coloring method to be used for the grid surface.
"solid" - The same color everywhere. See the "solid_color" argument for how to specify the color.
"continous" - A color lookup table is used for coloring based on depth.
"discrete" - A single color is selected from the color lookup table for each region between the contour lines. The color is taken from the color lookup table.
solid_color r g b
Specify the color to be used with "solid" color display.
The RGB values should be between 0.0 and 1.0.
show_contour_lines line_thickness
Display contour lines with the given line thickness.
The line thickness should be between 0.1 and 10.0.
The default line thickness is 1.0.
contour_line_color r g b
Specify the color of the contour lines.
The RGB values should be between 0.0 and 1.0.
The default color is black (0.0 0.0 0.0).
