Many Useful Nodes - for Blender Geometry Nodes

Many Useful Nodes

Has custom nodes for Geometry Nodes, that I use to develop stuff.
If you save the .blend file in an Asset Library folder, the nodes will appear in the Add drop-down inside the Geometry Nodes editor.

Geometry Read and Modify

1. Curve to Mesh with UV
   Like the Curve to Mesh node, but with generated UV map, like I showed in this video: https://youtu.be/Pzs_Uvb9DTg?si=-THTokc8uzyLqaJL
2. Factor Adjust
   With this you can adjust the values of the curve factor from the Spline Parameter node
3. Curve Attributes
   A quick way to capture most used curve attributes.
4. Randomize Point Indices
   With this you can randomize the indices for points in a mesh, on a curve or a point cloud.
5. Set Polygon Perimeter
   Define the input radius for a regular polygon, made from a mesh circle, by defining it's Perimeter and number of sides.
6. Index Selection
   Select up to 10 defined indices from a geometry. This is useful when prototyping and you need to select a bunch of specific points.
7. Visualize Index
   A simple way to preview the order of an index in a geometry. (You can use the Index Selection node to preview multiple indices)
8. Select Face
   Select a face from a mesh by index.

Math Nodes

1. Three-Way Mix (Float)
   You can mix three values: A, B, C, such that 0=A, 0,5=B, 1=C
2. Three-Way Mix (Vector)
   Similar to the float type, but for vectors.
3. Pythagorean Theorem
   Input the two legs of a right angle triangle and het the hypotenuse.
4. Convert Value
   Quick math functions on a value: N, -N, 1-N, 1/N, 2N, N/2
5. Positive Integer
   Input only positive integers (N ≥ 0), and do a quick modification to it.
6. Linear Range
   Like a Mix node, but with socketed Clamp input.
7. Logarithmic Range
   Like a Mix node, but the midpoint is at 0,1 (not 0,5). Useful in some situations, where the slider has a lot of influence at one end, but barely any at the other end.
8. Adder (GEO)
   Compact way to add up to 10 numbers.
9. Multiplier (GEO)
   Compact way to multiply up to 10 numbers.

Picker Nodes

Output 1 item out of a list. You can have a list with up to 10 items.

1. Pick Geometry
2. Pick String
3. Pick Float
4. Pick Integer
5. Pick Vector
6. Pick Boolean
7. Pick Collection
8. Pick Object
9. Pick Color
10. Pick Image
11. Pick Texture
12. Pick Material

Noise Nodes

1. Noise
   Like a Noise Texture, but with a bit more controls, like contrast and min and max values.
2. Noise along Curve
   Create a value variation along the length of a curve.

Animation Nodes

1. Animator
   Used to drive a value with controls for speed, offset and range.
