Up & Running with Muk3D
This tutorial provides a high level overview of Muk3D including how to accomplish simple tasks such as setting up project files, importing data, creating dams, calculating embankment and storage volumes, creating outputs, etc.
The tutorial relies on the "Pine River Hills" sample dataset provided when you set up Muk3D.
Load base dataset
Initiate modeling with LIDAR-derived xyz points. Learn to drag and drop files into the 3D window, navigate its interface, use key commands, and generate a triangulated surface from point data.
Create a surface
Learn to generate a triangulated surface from LIDAR data, save using Muk3D's unique methods, manage memory by unloading layers, and adjust terrain visibility through vertical scale exaggeration.
Grid the surface
Learn how to convert a triangulated surface into a grid in Muk3D, with a focus on grid spacing selection for accuracy and aesthetics. The chapter ends with creating and saving a new 10m grid layer.
Build a dam shell
Learn to design a dam shell in Muk3D. This chapter covers choosing or drawing dam centrelines, setting geometry, aligning slopes, and ensuring proper intersections for accurate volume calculations.
Basic volume calculations
Determine the dam's fill volume by comparing the topography and dam shell. Create elevation curves to observe fill progression. Finally, integrate the dam design into the base grid, ensuring to save modifications and associated outlines.
Calculate pond volumes
After adding a dam to a topographic surface, a pond's fluid capacity is determined by setting its elevation below the dam crest. A volume-elevation curve offers insights into storage variations and surface area, with results exportable to tools like Excel.
After modeling a dam and pond in Muk3D, users can capture realistic snapshots by overlaying georeferenced aerial photos. Muk3D provides tools for consistent screenshot capture, ensuring accurate site representation.
Save & restore viewpoints
In Muk3D, users can save specific view locations to ensure consistent snapshot angles. By setting a preferred 3D view, one can save it for later retrieval. This is especially useful for maintaining alignment across multiple snapshots. It's crucial to restore viewpoints with the same vertical exaggeration as when saved to avoid unexpected results.
Create a georeferenced overlay
Using Muk3D, you can overlay a georeferenced air photo on a base grid to highlight the dam. With the Tex module, the dam area is colored differently using the dam's footprint. After blending this with the air photo, the dam stands out in the image. Users can then return to saved viewpoints to capture snapshots.
