Using Spline Parameter As a Parameter for the Set Position Node

Since the individual strands here have different profiles, you can unfortunately not simply control this via the radius of the curve, because otherwise the individual profiles would be distorted. ...

How to correct curve tilt, tangents and normals of a curve?

So the task is to align the direction of the curves uniformly, and to adjust the Curve Tilt so that it follows a given vector. This can be solved as follows: First, the direction of the curve must be ...

how to make the end of a curve round like a semisphere?

I agree with @Vagabonk's comment, that's a neat method, but it does depend on Catmull-Clark's approximation of a square subdividing as a circle, which isn't perfect, and a level of subdivision you ...

How can the Screw modifier be implemented using Geometry Nodes?

Is that are you looking for? I think it is easy to rotate points depending on curve factor:

How can the Screw modifier be implemented using Geometry Nodes?

Here is an (almost) complete replica of the Screw modifier as a node group: The instructions for this can actually be taken, by and large, from the Blender documentation. The only differences to the ...

Geometry nodes - Split Curve by Control Points

To solve this task you would have to proceed as follows: Here I first capture the index of each point with Capture Attribute. Then I convert the curve into a poly ...

Spline parameter (factor) and instance on curve (No influence)

The following answers your question: As @Chris already noted: You have to capture the value for Factor with Capture Attribute before. ...However, I don't ...

Instance on every 10th node of curve

You can do it by using modulo in selection input: Also note that I've used Index as input instead of Spline parameter. Your spline is converted to mesh by Curve to Mesh node, Spline parameter doesn't ...

Create an Array of Mesh Conforming Curve that has a Start and End Point using Vertex Groups via GeoNodes

After working through your question, the following question emerges: How can I convert the vertex group "Start/End" into a curve? The answer is easily given: You would just have to filter ...

How can the Screw modifier be implemented using Geometry Nodes?

One of the advantages of the Screw modifier is that, with adjustment, it can give nice clean topology on a helix, with parallel subdivisions along the twist-axis, and relatively clean quads. Here's a ...

How can the Screw modifier be implemented using Geometry Nodes?

Making geometry with Curve to Mesh is a different thing than what screw modifier does. If you make a curve with a profile, the geometry is extruded along the curve, while screw extrudes geometry and ...

Right angle corners issue with Instances that follow Tangent Curve for Brick Wall with Geo Nodes

With the technique you used, the corners would always appear strange, because by moving the curve points along the tangents, they would always protrude a bit. In addition, you wouldn't be able to get ...

How can i make this text follow this circle path?

I would just use the Curve Deform to get the text bent around the curve and then add keyframes to rotate the curve itself. Rather than messing with the offset or whatever, that seems like a big ...

Spline parameter (factor) and instance on curve (No influence)

I would suggest using transform node before instancing. In this case, you don't need to use Capture attribute and leaf offset scales automatically with object scale and offset direction is always ...

Curves to mesh texture painting not working

The meshes have very bad topology- in this case the overlapping is causing the problem. So, you paint on the front faces (faces with normals outwards) but the back faces are flickering through. ...

How to make an object follow path and face the same direction as the other object

If I correctly understand your question, you can give a Follow Path constraint to your object with the curve as Target, then a Shrinkwrap constraint, with the surface as Target, enable the Align to ...
