CyrusBeck line clipping in c# - converted from C++ code at https://www.geeksforgeeks.org/line-clipping-set-2-cyrus-beck-algorithm/
You can simply create a clipping rectangle (polygon) with a set of Vector3 objects and then pass a start and end Vector3 object which defines the line. Two more Vector3 objects are passed as out variables and will contain the trimmed locations. And a CyrusBeck.CyrusBeckResult enum object which lets you know what was the result.
The boolean result is false if the result is DoesNotIntersect otherwise true.
bool IntersectsWithRectangle = CyrusBeck.LineClipping(clipRectangle, startVector, endVector, out startVectorTrimmed, out endVectorTrimmed, out result);
Along with a sample application that shows the result of the line clipping
- DoesNotIntersect,
- NotTrimmed,
- StartTrimmed,
- EndTrimmed,
- StartAndEndTrimmed
This code resolves issues with the original c++ code for horizontal lines not returning correct results.
