Minimal D3D11

Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube

Also check out Minimal D3D11 pt2, reconfigured for instanced rendering and with a smaller, tighter, simplified overall code structure, or Minimal D3D11 pt3, with shadowmapping + showcasing a range of alternative setup and rendering techniques.

Using Exp for zooming

One of the things I’m happiest to have learned in the past few months is a great use for Log + Exp in games when zooming in and out.

You may have already know that linear speeds work horribly for zooming, e.g.:

void Update() {
    scale = scale + speed * Time.deltaTime;
}
