I've a requirement to draw a few Circles and Curves connecting those circles. The circles have to be drawn in rows and columns fashion, so I guess using a GridPane would be a good choice. However, once all the circles have been drawn, how do I add curves to connect circles belonging to different columns on this GridPane?
I cannot use GridPane.add(node, row, column) for curves cuz that would add the curves to GridCells, neither does GridPane have .getchildren.add() method.
Is there a better design to this problem? Should I chose a different Pane that can help me plot circles in rows and columns along with the curves connecting them?

I want to identify the gap between two non-overlapping polygons as a new polygon. As displayed in the image below, the comparison will be between polygons A and C, and the result should be the black area (gap) between them. For display purposes the gap area is highlighted with a red line. Any ideas on how to approach this problem ?
I tried using boolean clipping operation in c++, such as difference and exclusiveOr, but given that the polygon where non intersecting the results where not the gap between them.
I have a question. I am trying to calculate the area of the following layer (see picture)
intersect area
I used the intersection tool to find the intersection between the layer of 4 overlapping buffers with another polygon (transformed from raster and therefore consists of many other polygons). This layers now consists of more than 200 polygons and most of them on top of each other. I actually want to calculate the 2D area of this layer, so I actually want to transform this layer of many polygons into one polygon so that you are able to calculate the area of this one polygon. My question is therefore, is there a possibility to transform this layer into polygons that are adjacent of each other and that there are no overlapping polygons anymore so I can calculate the area? Maybe there is another way to do this?
If understand your question correctly, you should be able to use the Dissolve Boundaries tool in ArcGIS; dissolve into one polygon; then calculate the area of that polygon.
I'm looking into creating a web application trough witch the user could draw an arbitrary picture on a canvas (only lines involved, no fill and no different colors) and then obtain an equation witch graphs the same picture they've drawn. Does anybody has any idea on witch approach would be the most sensible one?
I thought about simply using Bézier curves to draw and then calculate it's equation, but I wanted to know if there's any other approach which might be more appropriate.
I want to create a hexagonal lattice but it should be centered basically the whole lattice is a central hexagon and then layers of hexagon around, like shown in the figure. (may be my description is confusion, but right now that is how I am seeing it).
So I want to generate the coordinates for lattice below. I found many algorithm to create square lattice of hexagons but I want to ask if there is a algorithm for following lattice too.
Note:
N-th layer consists of 6N cells.
First cell of that layer in your representation has coordinate shift
(N*A*Sqrt(3)/2, N*A*3/2), where A is edge length.
First cell of that layer has number
2+3*N*(N-1) //(you have missed 14)
You can start from the first cell of Nth layer, make N more cells to left, N cells to left-down and so on...
Something really simple, like a big circle 'A' and a smaller circle 'B' inside it. Surprisingly no examples have nested circles.
Graphviz doesn't draw circles; it draws graph nodes of different shapes. You can get a node consisting of two concentric circles by setting the node's shape=doublecircle. Alternatively, you can draw two nodes with shape=circle at the same position. For a basic catalogue of node shapes, see https://www.graphviz.org/doc/info/shapes.html
