项目历史

The official README presents Triangle as a tool that takes a source image and turns it into an abstract image made of triangular tiles. Its documented process blurs the image, converts it to grayscale, extracts edges with a Sobel filter, adjusts the data with convolution, and then applies Delaunay triangulation.

The project is distributed as both a Go module/API and a command-line tool. Its README copyright dates the project to 2018, while the GitHub releases page shows later 1.x and 2.x releases, including v2.0.0 with CLI flag updates.

采用历史

Triangle found adoption among users who want an installable low-poly generator rather than a GUI-only art tool. Its README explicitly documents Homebrew installation, release binaries, Go installation, recursive directory processing, concurrent processing, URL inputs, SVG output, and stdin/stdout pipeline usage.

The GitHub repository page shows broad open-source interest for a niche creative tool, with thousands of stars and packaged release assets. That makes it a recognizable package for users browsing Homebrew media/image-processing formulae.

使用方式

Typical command-line usage passes an input image and output path, then adjusts parameters such as blur radius, point rate, edge factor, maximum points, grayscale mode, wireframe mode, stroke width, and SVG output. The tool can process single images, recurse over directories, or read and write through pipes.

For developers, the README documents an API where callers configure a `triangle.Processor`, decode an image, call `Draw`, and encode the output, which lets the same triangulation engine be embedded in other Go programs.

为什么软件包爱好者会关心

Triangle is significant in package-manager culture because it is a visually demonstrable CLI: `brew install triangle` gives a user a scriptable image transformer with reproducible parameters and no heavyweight creative-suite dependency.

It also illustrates the overlap between Go modules, release binaries, and Homebrew formulae for media tools. Package nerds care about that mix because it makes batch image effects portable across local scripts, CI asset generation, and terminal-first creative workflows.
