This type of intersection is easily done by the "min of the maxes" and "max of the mins" idea. To write it out one needs a specific notion for the rectangle, and, just to make things clear I'll use a namedtuple: from collections import namedtuple Rectangle = namedtuple('Rectangle', 'xmin ymin...

For more control over the rounded corners (beyond using a Stroke), you can combine 3 lines for the sides, and 3 bezier curves for the rounded corners. Use linear interpolation to get the start/end point of the lines and curves, with the corner points being the control point for the...

In the CAD industry, we would call this operation a 2d sweep, or a 2d planar sweep; in this case a 2d planar rotational sweep. (Not to be confused with a sweep line algorithm.) The resulting area would be the 2d swept area or 2d swept face, and the outline...

Push is simply adding items to the array it has nothing to do with Google Maps API. For a polygon to know its "closed" - make sure your first and last point in the array of points are the same - otherwise its not a valid polygon. if its not...

You can try alpha shapes. Basically it a delaunay triangulation without edges exceeding alpha. You can also traverse the convex hull of the triangulation and use a point in polygon test, for example with the rays method.

The easiest way is to using Path: <Path Stretch="Fill" Width="100" Height="100" Fill="Green" Data="M4.1561281,2.2702953 L4.8524521,2.2702954 4.8509674,3.963097 5.8969377,3.9630803 5.8969378,5.0916036 4.8524628,5.1061913 4.8524521,6.7843885 4.1561281,6.7843887 4.1559771,5.0877741 3.1116421,5.0916036 3.1116421,3.9630803 4.1556735,3.9654722 4.1561281,2.2702953 z"/> This Path you can easily edit in Blend using "Direct Selection". Polygon example: <Viewbox Width="50" Height="50"> <Polygon Name="myPolygon" Fill="Green"...

You need to convert your second image to raster (see here). sp.grid <- cbind(grid, col = predict(m, grid)) coordinates(sp.grid) <- ~ x + y gridded(sp.grid) <- TRUE sp.grid <- raster(sp.grid) Then your attempt works. grid.pols <- rasterToPolygons(sp.grid, n = 16, dissolve = TRUE) plot(grid.pols) class : SpatialPolygonsDataFrame features : 3...

downloadUrl is asynchronous, you need to use the data returned inside the callback routine. Right now, the bermudaTriangle polygon is constructed before the data is returned (outside of the callback function). function initialize() { var mapOptions = { zoom: 3, center: new google.maps.LatLng(49.724479, 17.578125), mapTypeId: google.maps.MapTypeId.TERRAIN }; map = new...

You don't need to use JQuery. A CSS transition will do fine. To keep things simple, use a <g> element with a transform attribute to move the coordinate origin to the middle of the object you want to scale. That way it will stay in the same place instead of...
