    webgl-operate (or gloperate for WebGL) is a TypeScript based WebGL rendering framework.

    npm Version Examples Documentation Travis CodeFactor

    webgl-operate encapsulates WebGL and provides various rendering capabilities such as common rendering controllers for single-frame and multi-frame rendering, raycasting, or progressive path-tracing as well as a multitude of common rendering processes and shaders. In contrast to most other rendering engines, neither a specific rendering approach/pipeline or style is favored nor a specific use-case is assumed. Instead, it features a basis for arbitrary rendering implementations and facilitates common rendering processes in an atomic manner. It can be used for, e.g., complex charting, volume rendering, point-cloud rendering, product visualization, learning webgl, raymarching or pathtracing, rendering implicit or procedural geometry, as well as modern rendering of 3D models and complex scenes.

    How to Install

    webgl-operate can be used as JavaScript or TypeScript library (types included) via npm:

    npm install --save-dev webgl-operate

    Alternatively, webgl-operate can be integrated as bundled JavaScript in your HTML:

    <script src="https://cdn.jsdelivr.net/npm/webgl-operate@latest/dist/webgl-operate.min.js"></script>

    Getting Started

    The canvas can be integrated into HTML5 as follows:

    <canvas id="multiframe">
        <!-- fallback -->
        Your browser does <strong>not support</strong> the <code>&lt;canvas&gt;</code> element.
    </canvas>
    

    This canvas can then be setup by associating the canvas element with a single-frame or multi-frame controller and attaching a renderer using JavaScript as follows:

    Source Structure

    directory description
    source most of webgl-operate's rendering and operational logic
    source/data contains, e.g., pre-built sampling patterns or other data
    source/shaders on build, shaders are packed into the dist as well (and includes are resolved)
    source/debug optional: various tools for run-time debugging
    source/viewer optional: generic viewer overlay and controller for webgl-operate based rendering
    website website demonstrating webgl-operate features (referencing examples)
    test tests of sources located in source

    NPM Configuration and Project Setup

    package.json specifies the following scripts that can be run by npm run-script <command>.

    command description
    build build for local development to ./build, creates a bundle with all facilities and a test website
    start starts a local start on port 4000 on the ./build directory
    start-watch runs build tasks concurrently in watch mode and starts start
    build-dist transpile sources and declarations to ./dist for distribution via, e.g., CDN
    build-lib transpile sources and declarations to ./lib/ for distribution via npm
    cleanup removes all build directories, i.e., ./build, ./dist, and ./lib
    lint code quality lint TSLint Rules: tslint.json
    doc build html documentation in dist/docs using TypeDoc
    test run unit tests using mocha and chai

    The above commands can be triggered directly from within a console (e.g., from within the Visual Studio Code terminal) or by using visual studio tasks. When first working on webgl-operate, use npm install to install dependencies. For development use npm run-script build and, e.g., npm run-script start to access the test website locally.

    • For deployment npm update and subsequent npm run-script prepack should be run.
    • For publishing the package to npm login to npm via npm login, then update the package version using npm version {major,minor,patch}, and, finally, run npm publish.

    Please note that deployment of documentation and examples is managed by CG Internals manually for now.

    Visual Studio Code configuration

    Please not that the workspace configuration .vscode/settings.json has automatic format on save enabled.

    All the above scripts, namely build, build-lib, build-dist, lint, cleanup, start, start-watch, doc, as well as test can be triggered from within Visual Studio Code. The intended workflow is to bind a key (e.g., ctrl+alt+t) to open the task selection and trigger the desired task. The tasks are configured in .vscode/tasks.json.
