This demo application belongs to the set of examples for LightningChart JS, data visualization library for JavaScript.
LightningChart JS is entirely GPU accelerated and performance optimized charting library for presenting massive amounts of data. It offers an easy way of creating sophisticated and interactive charts and adding them to your website or web application.
The demo can be used as an example or a seed project. Local execution requires the following steps:
-
Make sure that relevant version of Node.js is installed
-
Open the project folder in a terminal:
npm install # fetches dependencies npm start # builds an application and starts the development server -
The application is available at http://localhost:8080 in your browser, webpack-dev-server provides hot reload functionality.
This example demonstrates how to visualize 3D mesh models with customized coloring using the setVertexValues() method and PalettedFill.
To apply color to your 3D model using PalettedFill, you'll need to set values for each vertex.
First, every vertex of the model is iterated, and a weight for every sensor is calculated for that vertex.
This weight essentially describes how close to the vertex every sensor is.
Then, the sensor values are changed in real-time, and the vertex values are re-interpolated every time they do to update the colors.
This can be achieved by calling the setVertexValues() method, which accepts a callback function as an argument. This callback function should take a vertex as a parameter and return an array of colored values based on your criteria.
If you notice an error in the example code, please open an issue on GitHub repository of the entire example.
Official API documentation can be found on LightningChart website.
