# graphics-resources

A few of my bookmarks related to game development and realtime graphics programming.

## Bulk Download

You can use [gh-readme-scrape](https://github.com/mattdesl/gh-readme-scrape) to bulk download some of the content here for offline reading. For example:

```sh
gh-readme-scrape mattdesl/graphics-resources resources/ -e pdf,pptx,ppt --rename
```

This will download all PDFs and power-point slides into a folder called `resources`.
