LIS Visualization - visualization products from point clouds

This package contains tools for the creation of visualization products from point clouds, including an orthoimager and a point cloud photographer supporting different lens types.

Tool: Analytical Hillshading

Features
• calculation of an analytical hillshading based on pre-computed point normals
Applications
• shading of a point cloud

Tool: Colorize Point Cloud by Morphology

Features
• attachment of a morphological shading (based on topographic openness and slope) as RGB values to a point cloud
• calculation of point normals, optional
Applications
• morphological shading of a point cloud

Tool: Colorize Virtual Point Cloud by Morphology

Features
• attachment of a morphological shading (based on topographic openness and slope) as RGB values to a point cloud
• calculation of point normals, optional
• automated subset extraction from a virtual point cloud based on a polygon shapes layer
Applications
• morphological shading of point cloud subsets

Tool: Direction Vectors

Features
• creation of direction vectors from a point cloud attribute as 3D line shapes layer
• control of vector length
Applications
• construction of 3D direction vectors as line shapes layer for visualization
• e.g. visualization of normal vectors together with the point cloud in the '3D Point Cloud Viewer'

Tool: Point Cloud Orthoimager

Features
• orthoimage (orthorectified raster) creation from all points detected within a user specified range to a profile line
• profile line (x-axis of the image) is defined by a line shapes layer or by coordinates
• AOI is aligned left or right to the profile line, or centered on the profile line
• gridding of a user specified attribute
• additional output: depth image (range)
Applications
• orthoimage creation from, e.g., terrestrial point cloud data
• distance measurements in the output image
• point cloud visualization

Tool: Point Cloud Orthoimager [interactive]

Features
• orthoimage (orthorectified raster) creation from all points detected within a user specified range to a profile line
• profile line is interactively digitized in a Map View
• AOI is aligned left or right to the profile line, or centered on the profile line
• gridding of a user specified attribute
• additional output: depth image (range)
Applications
• orthoimage creation from, e.g., terrestrial point cloud data
• distance measurements in the output image
• point cloud visualization

Tool: Point Cloud Photographer

Features
• image creation from point clouds by modelling a camera pose, focal length and camera sensor
• lense types: tele, panorama, or hemisphere
• adjustable focal length and sensor size
Applications
• image creation from point clouds
• reproduction of photographs
• creation of virtual hemispherical images (VHI)
• point cloud visualization

Tool: Shading Normals

Features
• computation of normal vectors describing the surface orientation at each point
Applications
• normal vector computation for normal-based shading e.g. in the '3D Point Cloud Viewer'
