vector-graphics

I am trying to render some locally-stored and vector-based tiles download from OpenMapTile. The reason I am doing that is because my end application will only run on a computer that cannot be connected to the internet. I have read many different things on whether or not leaflet can render vector-based tiles but it seems that it can from some examples. It seems that it is not possible with Vector Grid that only does raster tiles but that it is possible with Leaflet.TileLayer.MBTiles So I tried to do just that but always stumble upon an empty page when trying it out... I have the controllers for

As a result to a call to findHomography() I get back a 3x3 matrix mtx[3][3]. This matrix contains the translation part in mtx[0][2] and mtx[1][2]. But how can I get the rotation part out of this 3x3 matrix? Unfortunaltely my target system uses completely different calculation so I can't reuse the 3x3 matrix directly and have to extract the rotation out of this, that's why I'm asking this question. Generally speaking, you can't decompose the final transformation matrix into its constituent parts. There are some certain cases where it is possible. For example if the only operation preceding the

I have written a vector-based 3D editor (UI customized somewhat like technical drawings). I now want save the vectors/drawing data in portable formats. Which formats are available; which (one?) of them are the most widely accepted, and where can I get hold of the format specifications? Commercially, many users will look for AutoCAD DWG and Bentley DGN formats. While not free, libraries for producing these formats can be found from the open design alliance The GIS community use shape files quite a bit for vectorised 3d models, a free SDK for shape files can be found here . The OSG library is

I would like to edit SVG files using some scripting language (preferably Python). In particular, I would like to merge two SVG files, add some annotations, and arrange them in a larger image. Is there any software available for such purposes? Thanks, Bartosz UPDATE I finally decided to use the approach proposed by nosklo. You can find the code of SVG handling python module on github repo . I also described how to use it in this post nosklo You could use something like lxml - after all SVG files are XML. It's available from PyPI pip: https://pypi.python.org/pypi/lxml/ I don't know if you could

For an article I am generating plots of deformed finite element meshes, which I visualize using matplotlib's polycollection. The images are saved as pdf. Problems arise for high density meshes, for which the naive approach results in files that are too large and rendering too intensive to be practical. For these meshes it really makes no sense to plot each element as a polygon; it could easily be rasterized, as is done when saving the image as jpg or png. However, for print I would like to hold on to a sharp frame, labels, and annotations. Does anyone know if it is possible to achieve this

I'm looking for a plugin for inkscape (or any vector based editor for that matter) to see a window with the code next to the window with the graphical objects for SVGs. Both windows would be dynamic, meaning that if you change something in the graphical view it automatically updates the code, and changing the code would automatically update the graphical object. Also it would be nice if selecting an object would highlight the relevant code. I have had a look here but didn't see anything like this: http://wiki.inkscape.org/wiki/index.php/Extension_repository Does anything like this exist or
