Approximating Perspective Transforms in SVG for Lightweight 3D Rendering
2025-06-05
A developer built a vanilla Typescript 3D renderer to render circuit boards made in React as SVGs. Since SVGs lack native perspective transforms, they cleverly used affine transformations and image subdivision. By splitting the image into many sub-regions and applying locally-correct affine transforms to each, they approximated perspective. Results showed excellent visual quality with 512 subdivisions while keeping SVG file sizes manageable. This approach offers a neat solution for displaying and reviewing circuit board changes on GitHub.
