  • Modelling haul roads using Bezier splines

    The current version of Haul Infinity uses standard straight-line segments to display roads. In future, we’re looking to transition to rendering smooth roads. The benefits of this approach include: more accurate distance calculations, and the capability to calculate and visualize road curvature for use in applying speed limits. The following two images show a classic…

  • Faster path finding in C#

    Until recently at work, we’ve been using the excellent QuickGraph library for finding optimal haul routes across pits. This week, I replaced it with my own creation, SpryGraph, written from the ground up for performance. (SpryGraph is not a replacement for QuickGraph, due to only having a tiny subset of the features) Path finding is…

  • Synchronising music playback on networked computers

    , , , ,

    Now and again I get questions about SyncBoss – software for synchronizing music between computers between LAN which I wrote during my Uni daze. Sharing with three housemates at the time, an eclectic range of music playing all at once was the norm. While Bon Jovi, Mos Def and Tiesto can sound great in isolation,…

  • Draping an image over a triangulation

    I recently added a feature to Alastri HaulInfinity to drape an image over a 3d triangulation.The idea is to help engineers design their haul network by allowing them to reference an aerial photo. Vertically projecting the photo onto the terrain is quite straightforward, and not discussed here. To perform an affine transformation based on registration…
