Nice one, thank you great introduction to Geometry Nodes. I was wondering if you could explain why the Spline Parameter which is mapped 0-1 on the length of the curve, became mapped to to Z axis when meshed? Really hoping for a part two :)
Thanks! So at 8:33, you see an animation that shows how a torus is created. You can think of adding a circular profile to a curve as placing many circles along that curve and then connecting them to create the final mesh. We have the spline parameter mapped from 0 to 1 on the profile curve. Then, the "mesh to curve" node places many circles (as many as there are points on the main curve) along the main curve. Each circle still retains the custom attribute that we saved with the "store named attribute" node, specifically the splineFactor attribute. When the "curve to mesh" node connects these circles with edges and faces, the attribute still remains. It looks like it is mapped to the Z-axis, but if you rotate the profile curve along the Z-axis just before connecting it to the "curve to mesh" node using the "transform geometry" node, you will see that the attribute on the torus is also rotating. I hope this explanation clears things up a bit. If you have further questions, feel free to ask. Glad to help! :)
@@jakobdesign8066 Ah, now it makes sense! Thank you so much for taking the time to provide such an in-depth explanation. I really appreciate it, and it helped me better grasp what is happening!
Excellent video! I'm looking forward to the rest!
