QUESTION

Subtracting SVG paths programmatically

Asked 2022-Feb-11 at 20:51

I'm trying to find a way to subtract a SVG path from another, similar to an inverse clip mask. I can not use filters because I will need to find the intersection points of the compound path with other paths. Illustrator does this with the 'minus front' pathfinder tool like this:

The path of the red square before subtracting:

This is a nontrivial problem in general.

It can be solved easily (little code) if you can accept rasterizing the shapes to pixels, perform the boolean operation there, and then vectorize back the result using marching squares + simplification.

Known algorithms to compute instead a somewhat exact* geometric result are quite complex and difficult to implement correctly while keeping them fast.

Clipper is an easy to use library to perform this kind of computation in C++, with ports to Javascript.

Please note that what is difficult is to correctly handle edge cases (e.g. when input lines are partially overlapping or vertices fall exactly on a line and when the result includes zero-area parts).

Code that only reasons about cases in which crossings are clear is a lot easier to write, but unfortunately can produce results that are macroscopically wrong when those edge cases do actually happen.

Floating point math is too unpredictable to be used for these computations... see for example https://hal.inria.fr/inria-00344310/document for a detailed discussion of the kind of issues that will be present when using floating point math for exact geometric computation.

Even a "simple" equation like the one that tells if three points are collinear, clock-wise or counter-clokwise behave crazily when computed with floating point math... (images from the paper)

(*) The coordinates of the intersection of two segments with integer coordinates cannot, in general, be represented exactly by double-precision numbers; thus the result will still be an approximation unless you use a numeric library with support for rationals.

QUESTION

Merging two bezier-based shapes into one to create a new outline

Asked 2022-Feb-11 at 15:12

Lets say I have the data to render two overlaying bezier-based shapes, that are overlapping, displayed in a svg or on the canvas (doesn't really matter where). I would like to calculate the outline of the shape resulting from the merge of the two shapes, so that I have a clean (new) outline and as few nodes and handles as possible. I would like to achieve the effect that vector programs like adobe illustrator offers with Pathfinder > Add or the font program glyphs with Remove Overlap. Example: https://helpx.adobe.com/illustrator/using/combining-objects.html

Is there possible a library or a concept for that task? I am working with javascript in the browser, but any other source for how to make such a calculation would help as well.

It is also important, that this calculation happens before the rendering an agnostic to the rendered result (be it svg/canvas).

In the illustration bellow, on the left side is the input shape. and on the right side the expected result. I have the data, meaning all the nodes and handles (from the bezier curve) and I would like to calculate the coordinates of the red (nodes) and green dots (handles) on the right side.

Paper.js might be the perfect library for this task:
In particular it's Boolean operations – like unite() to merge path elements. The syntax looks something like this:

Simply said:
a) VS Code is not affect by vcpkg integrate install, only MSBuild is ...
b) setting the CMAKE_TOOLCHAIN_FILE only works before the very first project() call
c) setting CMAKE_TOOLCHAIN_FILE before project() via cmake.configureSettings or other means does not work if there is already a configured cmake cache. d) don't modify CMAKE_PREFIX_PATH

So starting from a clean cmake build without any cache: Set CMAKE_TOOLCHAIN_FILE before project() by any means you want and it works. You might also need to set VCPKG_TARGET_TRIPLET. (using #include seems fine)

Get distance between two locations using non-solid blocks with bukkit

Asked 2021-Nov-27 at 15:06

My goal is to achieve that players on my bukkit server only hear each other, when there are no walls between them. So my idea was to get the distance between the sender of a message on the AsyncPlayerChatEvent and the recipient (getRecipients()) using a (Flying)Pathfinder(Goal), so that there is a path (throught the air) to the other player. If there is no way or the path is too long, I would remove the recipient from the list.

QUESTION

Is there a (CSS) filter to cut out the outlines of an image on top of another image?

Asked 2021-Sep-04 at 08:17

I've got two images on top of my webpages. One is a rectangle-shaped JPG file banner, the other is a wave-shaped SVG vector file. Similar to how Adobe Illustrator has its pathfinder tool to cutout shapes: Is there any way to invert-cutout the wave from the banner, using any sort of CSS filter or blend mode or something?

The reason I want to do this using CSS is because it would only require me to change one HTML template for the banner. Otherwise I would have to edit 125+ unique banner image files. Editing the wave file is not a problem if needed, as I would only need it once for the banner template.

Example banner:
