LViz - LiDAR / ALSM 3D Visualization tool

LViz is a tool developed by Jeffrey Conner in the Active Tectonics Research Group at Arizona State University. Designed for 3D visualization of LiDAR / ALSM point and interpolated data, the tool offers import of LiDAR point cloud data (delimited text file) or interpolated surfaces (in ascii or arc ascii grid formats). LViz also offers texture mapping and user control over display settings such as data and background color. LViz was originally written for visualization of outputs from the GEON LiDAR Workflow (GLW) (additional GLW information here) and is designed to run on Windows platforms. Although originally conceived for the 3D visualization of LiDAR data, LViz can be used to view any 3D point cloud data such as seismicity or gravity.

LViz is an evolving piece of software, new versions will be released periodically (see below for most recent version).

New Features in LViz Version 1.4.1.1:

• Import of files with a column header and the ability to specify which column to use for x, y, and z coordinates.
• Color points based upon an attribute in a 4th column. This feature is currently only implemented to work for classified return data with values of G (ground), V (vegetation) and S (structure). Point symbolization by attribute will be fully implemented in the next version of LViz.
• Updated "How-To" file in the zip.

LViz Version 1.2.0:

• Multiple layer import is now supported. Up to 4 layers of any supported type can be imported and displayed simultaneously.
• Added lighting and shading to interpolated layers when displayed in polygon mode.
• Combined Grid and Arc ascii imports. LViz will now automatically detect which one is being imported.
• Updated settings menu. Settings can now be changed for each layer.
• Added layer menu to allow user to toggle the visibility of the imported layers.
