h2. Description
Command using multiple downsampled/decimated versions of the dataset for fast display of large datasets.
h2. {color:#000000}{*}Syntax for general commands{*}{color}
{color:#333333}{*}frustum{*}{color}
{indent}Create a polygonal model of the current view frustum in the active dataset.{indent}
{color:#333333}{*}automatic{*}{color} {color:#333333}"on" \| "off" {color}
{indent}Turn the automatic level of detail level selection on and off.{indent}
{color:#333333}{*}epsilon{*}{color} {color:#333333}value{color}
{indent}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. {indent}
{color:#333333}{*}glreport{*}{color}
{indent}Prints information about the active opengl GPU in the Messages window.{indent}
{color:#333333}{*}glextensions{*}{color}
{indent}Prints information about the opengl extensions in the Messages window.{indent}

h2. {color:#000000}{*}Description{*}{color}
{color:#333333}For displaying point cloud data.{color}
h2. {color:#000000}{*}Arguments{*}{color}
*range* min max
{indent} Specify data range to be used for color lookups. When not specified the range of the data is used.
{indent}
*zerocenter*
{indent}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))
{indent}
*point_size* size
{indent} Size of the points to display. The default value is 1.0.
{indent}
*color_filling_method* "solid" \| "continous" \| "discrete"
{indent} 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.
{indent}
*contour_increment* distance
{indent}Display evenly spaced color regions with distance in meters between regions.
{indent}
*contour_values* num_values value1 .. value32
{indent}Explicitly specify the color regions.
num_values is an integer, valueXX are floats representing depth in meters.
{indent}
*contour_aml*
{indent}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.
{indent}
*solid_color* r g b
{indent}Specify the color to be used with "solid" color display.
The RGB values should be between 0.0 and 1.0.
{indent}
*show_all_points*
{indent} Always show all the points in the dataset.
{indent}
