Gaussian blur is a simple effect, particularly well suited to GPU architecture. In this first part, we will explore how to implement it in the browser using WebGPU.

In this second part, we will leverage the separability of the Gaussian kernel to improve the performance and efficiency of the implementation. We will also see how to measure actual execution times on the GPU.

Robust, reliable, and maintainable code requires the support of an adequate test suite, and code that leverages the GPU is no exception. In this article, we will see how to test Gaussian blur using the QUnit framework.
