Hi there,
I am reviving this topic as I would like to enhanced the radiation solar dome with iso-value contour. I think this kind of plot is a lot more readable with those lines or with discret colors.
After few searches, the algorithm behind the hood seems to be “marching square” (more info here)
An alternative is to extrude the mesh (if it is flat / with Z = vertex value) and do plane intersection (with Z plane = iso value) and project back the contours on the mesh. This is what this legacy component seems to do right ? Are there any plans to add it to LB 1.6 ?
