I have gotten fairly decent for a hobbyist with Blender and I am just starting to get into the geometry nodes. I have played with them but not done anything serious because I am rather stuck on what seems like some basic ideas.
I have figured out how to make spirals and with that I wanted to make a spiral staircase. I thought it would be a simple matter of creating a spiral, turning that into points, then instancing a cube shape (the treads) onto the points. But everything I try just goes sideways.
I am not looking for a full "how to" because I really want to figure out most of the image myself. I know there is a lot to a staircase like tapering the treads and putting on a railing and and and and... But I am totally stuck on how to get the treads to lay flat. I think if I can get past that one issue, I can create something of interest on my own at that point.
So what I found is I can create the spiral and attach treads to it. But they don't rotate around the center of the spiral. They all point in same direction.
My first thought was to attach the point rotation to the instance rotation but that just made a massive mess of things.
I fiddled with adding a transform node and tweaking the rotation on my own but it just kept getting worse and worse.
To give an idea of what I am trying to get to I created a bruit force layout by creating one tread by hand in layout mode and just duplicating it a bunch and manually rotating each tread 5 degrees. This is just so you can visualize what I am trying to do.
Any pointers you might have would be greatly valued. Again, I just want enough info to get me going and I think getting the treads to lay flat would do that.
Your input is greatly appreciated.
