This is the Windows app named WebGL Heatmap whose latest release can be downloaded as webgl-heatmapsourcecode.zip. It can be run online in the free hosting provider OnWorks for workstations.
Download and run online this app named WebGL Heatmap with OnWorks for free.
Follow these instructions in order to run this app:
- 1. Downloaded this application in your PC.
- 2. Enter in our file manager https://www.onworks.net/myfiles.php?username=XXXXX with the username that you want.
- 3. Upload this application in such filemanager.
- 4. Start any OS OnWorks online emulator from this website, but better Windows online emulator.
- 5. From the OnWorks Windows OS you have just started, goto our file manager https://www.onworks.net/myfiles.php?username=XXXXX with the username that you want.
- 6. Download the application and install it.
- 7. Download Wine from your Linux distributions software repositories. Once installed, you can then double-click the app to run them with Wine. You can also try PlayOnLinux, a fancy interface over Wine that will help you install popular Windows programs and games.
Wine is a way to run Windows software on Linux, but with no Windows required. Wine is an open-source Windows compatibility layer that can run Windows programs directly on any Linux desktop. Essentially, Wine is trying to re-implement enough of Windows from scratch so that it can run all those Windows applications without actually needing Windows.

WebGL Heatmap
DESCRIPTION
webgl-heatmap is a browser-side rendering library that uses the GPU via WebGL to draw smooth, continuous heatmaps from large numbers of data points. Instead of relying on CPU-bound canvas operations, it leverages fragment shaders and additive blending to accumulate intensity and colorize results in real time. The API lets you push points or weighted samples into a buffer and then renders a gradient map where hot areas emerge organically from density rather than discrete markers. Because most work happens on the GPU, it scales well as the number of points grows and remains interactive for animations, live telemetry, or dynamic overlays. The library focuses on visual quality, producing anti-aliased, blur-free gradients that look good at various zoom levels and resolutions. It fits well into data-viz stacks where you need a responsive heat layer on top of maps, charts, or custom canvases, and it is compact enough to embed in dashboards and demos without heavy dependencies.
Features
- GPU-accelerated rendering via WebGL for smooth heatmap performance
- Supports floating point textures and custom gradient mapping
- Methods to add individual or batches of data points (x, y, size, intensity)
- Operations: update, display, multiply (scale), clamp, blur etc.
- Fallback / error handling when WebGL or required extensions are absent
- Example usage and demo included (example.html)
Programming Language
CoffeeScript
