vector-graphics

This area is hardly documented online and it would be great to see a working Swift 3 example, of say, a custom drawn cube with manual SCNvector3s. There is this in objective-C but not Swift. This might not be a usual form of question but I know it would help many. If there is somewhere I missed, please mention. The documentation is not very helpful scngeometrysource, etc. Thanks 0x141E A custom geometry is constructed from a set of vertices and normals. Vertices In this context, a vertex is a point where two or more lines intersect. For a cube, the vertices are the corners shown in the

I've been testing out Andorid Studio with the new gradle plugin - 1.4.0-beta3. I've been trying to import my own vector assets, made in Inkscape. However I keep getting import errors. The error message includes lots of tags in the svg that arn't supported. In mm_card.svg: ERROR@ line 54 <defs> is not supported ERROR@ line 56 <linearGradient> is not supported ERROR@ line 58 <stop> is not supported ERROR@ line 62 <stop> is not supported ERROR@ line 66 <stop> is not supported ERROR@ line 70 <stop> is not supported ERROR@ line 74 <stop> is not supported ERROR@ line 78 <stop> is not supported ERROR

I am using a drop shadow filter inside an SVG file that is embedded using an img tag. On my MacBook, it looks fine in Safari. However, in mobile Safari, the graphic gets really pixelated and loses all it's sharpness. When the filter is not applied, the SVG renders fine. Is there any way to fix that besides to pass on the filter? You should try explicitly setting the "filterRes" attribute of the filter to a value that matches retina displays. This problem is still relevant in 2018, and I've found a solution. You can duplicate the element you give the filter to, place it below the actual element

I've come to a conceptually difficult problem. In short, I need to find the vector path of two vector paths combined through different boolean operations. Such as the Union, the Difference, the Intersection, and Subtraction. It would be nice if I could do it similar to how Canvas does it's globalCompositeOperation. How in the world would I go about doing this? There is a JavaScript library that allows for boolean operations on SVG paths under the condition that the path is a polygon. Using a high enough sampling, the beziers can be polygonized to such a high quality that the visual result is

All the time previously I was exporting Matlab figures in a raster format (JPG, PNG) Is there a way to export a plot from Matlab in a vector format (SVG). I need it to inset that plots into LaTeX document. The only thing, I have found so far is a plugin from mathworks and the answer from stackexchange , but this looks rather too complicated There is also matlab2tikz and matlabfrag which exports to eps with annotation for importing to LaTeX. Here is an example of mine where I've used matlabfrag. I've also discussed this with a Mathworks engineer, who agreed that there is not a nice-and-ready

Looking at the cross-platform nature of potrace http://potrace.sourceforge.net/ , is it possible to compile this for iOS? If so, how? Paul Guyot Yes, it is possible to compile potrace for iOS. As a matter of fact, most open source libraries using standard (GNU) configure tools that compile on MacOS X will easily compile on iOS, because they are likely free of platform-specific code (e.g. linuxisms ) and standard configure tools allow cross-compilation. You can compile these libraries in the shell by pointing configure to the proper toolchain and SDKs. Paths changed with Mavericks and Xcode 5,

Given an arbitrary sequence of points in space, how would you produce a smooth continuous interpolation between them? 2D and 3D solutions are welcome. Solutions that produce a list of points at arbitrary granularity and solutions that produce control points for bezier curves are also appreciated. Also, it would be cool to see an iterative solution that could approximate early sections of the curve as it received the points, so you could draw with it. The Catmull-Rom spline is guaranteed to pass through all the control points. I find this to be handier than trying to adjust intermediate control
