PicoGK v2.1.0

[leap71]

PicoGK v2.1

This release adds a number of new features for dealing with coordinates, including non-Cartesian ones.

Release Notes

• NEW: Added Polar 2D coordinate type
• NEW: Added Cylindrical 3D coordinate type
• NEW: Added Spherical 3D coordinate type
• NEW: Added Viewer.AddCross and Viewer.AddArrow functions
• NEW: float.bAlmostZero and Vector3.bAlmostZero extension functions.
• NEW: Added float.bAlmostLessOrEqual and float.bAlmostMoreOrEqual extension functions.
• NEW: Vector3/Vector2 extension functions vecNormalized and vecSafeNormalized.
• NEW: Vector3 extension functions to convert from local to world coordinates and back. You can now write vec.vecPtWorld(from) etc.
• NEW: Added Rad.TwoPi constant to avoid having to constantly write 2*float.Pi for angles in radians.
• FIX: Renamed Frame3d.vecFromWorld to Frame3d.vecPtFromWorld for consistency

I just pushed this new release. Most notably, it adds extension functions to the Vector3 class to easily deal with Frame3d conversions. We will push some changes to the Shape Kernel in the coming days that allows interoperability between Frame3d and LocalFrame.

So you can do something like that:

LocalFrame oFrame = new(...);

Vector3 vec = new( ... );

Vector3 vecWorld = vec.vecPtWorld(oFrame);

Vector3 vecBackToLocal = vecWorld.vecPtLocal(oFrame);

This will make the code for coordinate transforms a lot easier.

I also implemented Polar, Cylindrical, and Spherical coordinates as types.

This just-published Coding for Engineers book chapter explains how to use them.

PicoGK 2.1 is available as NuGet as usual.

Enjoy,
