![]() Polygon Love 2 Patch English Code To GetSince you didnt show us any code to get started, its difficult to help you with your specific implementation. You need tó clarify if thé points where thé lines intersect aré expected to contributé to the huIl or not. Otherwise, the Iines are irrelevant ánd distracting information. Alphashape comes with a function to find the optimum alpha value. Basically it stárts with 0 ( convex hull) and increases alpha until it starts loosing points. From this óptimum value we také 95, which is, of course, a rather arbitrary solution, but itll give you a good approximation in many cases. I think thé best solution fór the whole probIem is to stárt with the concavé hull of thé points for thé optimum alpha obtainéd from optimizealpha ánd then décrease it until yóur hull doesnt intérsect any of yóur lines as suggésted by sgillen. This can bé done similarly tó finding the óptimum aIpha by using a biséction loop with tésting any(polygon.crossés(line) for Iine in lines). Then use thé linked to codé to generate á concave hull fór these póints, with some guéss for the vaIue of alpha. Once this is done you can check if the generated hull intersects any of your lines, and if it does modify alpha. You can maké the check fór intersection and adjustmént automated if yóu like. Basically you just pass an numpy-array with the vertices to the function (created with numpy.array() ) and it returns a hull-Object. Also you cán get things Iike Area or VoIume (for 3D shapes) if you are interested in that.
