Below I collected relevant links and papers more or less pertaining to the subject of tetrahedral meshes. 
It's an ever-growing list.

// Creating a node graph editor for Dear ImGui
// Quick sample, not production code! 
// This is quick demo I crafted in a few hours in 2015 showcasing how to use Dear ImGui to create custom stuff,
// which ended up feeding a thread full of better experiments.
// See https://github.com/ocornut/imgui/issues/306 for details

// Fast forward to 2023, see e.g. https://github.com/ocornut/imgui/wiki/Useful-Extensions#node-editors

// Changelog
// - v0.05 (2023-03): fixed for renamed api: AddBezierCurve()->AddBezierCubic().

Graphical User Interfaces

For the last few weeks I spend some time coding, writing and cleaning up my notes from almost a year since I published nuklear.

Basically this is a possible implementation for a graphical user interface builder backend with support for an immediate mode style API. So it provides a way to define non-mutating UI state, an immediate mode style API for dynamic UI components (lists,trees,...) and a combination of both.

The core implementation is ~800 LOC without any kind of default widgets or extensions. At first this seems quite counter intuitive. However since the inherent design allows for lots of different ways to define any widget like buttons it does not make sense to provide a specific default implementation. The way this code was architectured furthermore removes the need for style/skinning configurations used in Nuklear since widget painting is just calling a small

In shader programming, you often run into a problem where you want to iterate an array in memory over all pixels in a compute shader
group (tile). Tiled deferred lighting is the most common case. 8x8 tile loops over a light list culled for that tile. 

Simplified HLSL code looks like this:

Buffer<float4> lightDatas;
Texture2D<uint2> lightStartCounts;
RWTexture2D<float4> output;
