Open source maintenance is often a stressful and thankless job.

I'm doing Open Source primarily because I love it. The social aspects, the for-the-good angle and for the challenge of engineering this to work for everyone. I also do it because it is my full-time job and getting food on the table and provide for my family is not unimportant. It may come as a … C...

This clock composite glyph is entirely built in Slughorn and rendered in OpenSceneGraph. The animation is done by individually transforming layers (eg the clock hand).

Did I mention GRADIENTS?!!?! Slughorn now supports multi-stop linear and radial color gradients and COLRv1 gradient specification.

Graphics APIs and shader languages have significantly increased in complexity over the past decade. It’s time to start discussing how to strip down the abstractions to simplify development, improve performance, and prepare for future GPU workloads.

Slughorn rendering its own logo in orthographic and perspective views (via our companion osgSlug project).

We're barely scratching the surface of the potential of this algorithm in the right hands.

Initial public release coming shortly. Daring/crazy people can certainly find the repo on their own right now if they are ambitious enough.

Each layer of color in a glyph can be individually transformed, even animated.

We also have axlotls. For ... reasons.

GPU rendered curve-stroke AXLOTLS people! Are you SEEING THIS???!?1!?

We can expand centerline-based stroke graphics with a width (even variable) and endcaps to produce stroked linework rendered on GPU. Forget NVPR, this is portable across all GPU vendors.
