svg2prwm

CLI tool to convert SVG files into PRWM files.

Packed Raw WebGL Model is a binary file format for nD geometries specifically designed for JavaScript and WebGL with a strong focus on fast parsing (from 1ms to 0.1ms in Chrome 59 on a MBP Late 2013). More information on this here.

Currently this tool only support the conversion of SVG containing a path.

Installing

With npm do:

npm install svg2prwm -g

CLI Usage

svg2prwm -i inputFile -o outputFile [OPTIONS]

Options

• --normals : Generate a set of normals.
• --uvs : Generate a set of uvs.
• --separateTriangles : Make sure no vertex is shared between multiple triangles. Produces larger files.
• --scale : Scale used for the bezier curves. A higher value means a better resolution.
• --simplify : Simplification amount. A higher value means a more simplified mesh.
• --be : Indicate that the destination file must be in Big Endian byte order. By default the destination file is in Little Endian.
• -q, --quiet : Quiet mode. Silence the output to the console.

API

svg2prwm.convert(svgString, options)

Arguments

• svgString : The svg file as a string.
• options : Options
  • normals : Generate a set of normals.
  • uvs : Generate a set of uvs.
  • separateTriangles : Make sure no vertex is shared between multiple triangles. Produces larger files.
  • scale : Scale used for the bezier curves. A higher value means a better resolution.
  • simplify : Simplification amount. A higher value means a more simplified mesh.
  • bigEndian : Indicate that the destination file must be in Big Endian byte order. By default the destination file is in Little Endian.
  • quiet : Quiet mode. Silence the output to the console.

Example

$ svg2prwm -i original.svg -o destination.prwm --normals --scale 1 --simplify 0.5
