The task remains the same which is to extract intelligent data from images and (or) point cloud data (LiDAR, DSM, point clouds) in the form of vectors and attributes for various disciplines. VrThree (VrLiDAR) offers the ability for photogrammetry firms to utilize existing personnel and software while offering new and powerful tools for other mapping disciplines such as architecture, all types of surveying and engineering. VrThree (VrLiDAR) is software that integrates point cloud data into the time tested Vr Mapping Software packages, VrOne® and VrTwo. This package allows the display and editing of LiDAR point data in 2D and in true three-dimensional stereo. The four configurations available in VrThree enable vector, symbol and text entities to be collected and edited using the extensive VrOne®/VrTwo mapping tools. Mapping professionals now not only need the ability to collect three dimensional vector data from traditional photogrammetric sources.

More than a Spring Calculator. ODOP:Spring is a spring design application of the problem-independent Open Design Optimization Platform (ODOP) software. It finds solutions for demanding spring application requirements in mechanical engineering and machine design. Most coil spring calculators require users to manually input values – such as wire diameter, coil diameter, free length and number of coils – and then repeatedly re-analyze until an acceptable solution is reached. ODOP’s ability to invert formula relationships removes that guesswork. Spring design equations are backsolved to meet constraints placed on the problem variables. Need to identify the lightest-possible material weight? Ensure a long spring life and low risk of failure? Our helical coil spring design software can find the constrained extreme of any variable, whether independent or dependent.
