Texture Sources
Three nodes that create textures from nothing — LoadImage for files, SolidColor for flat fills, and NoiseTexture for procedural Perlin, Simplex, and Worley patterns.

The devlog
145 posts of what shipped, what broke, and what got deleted on the way to 1.0. Numbered in order; start anywhere.

GPU Texture Pipeline
Lux gets a GPU-resident texture processing engine — handle-based allocation, free-list pooling, shader caching, and a declarative op system that keeps plugins completely decoupled from wgpu.

Stop Cloning Everything
Four performance improvements that boil down to one lesson: stop copying things you don't need to copy. Arc-wrapped layers, zero-alloc output maps, borrowed spread slices, and a wire drag fix.

The Cleanup Episode
A deep code review found 39 issues, a 274KB font was being copied every frame, circles were made of 360 line segments, and five unwrap() calls were lurking in the render pipeline. We fixed all of it.

Shapes, Docs, and Polish
A big session: 6 new shape primitives, inline documentation for every node and 203 pins, smarter tooltips, z-ordered nodes, search-at-cursor, a Filter node, and an adversarial review that caught 14 issues before users could.

Filter: The Missing Spread Node
A new Filter node lets you keep only the elements you want from a spread using a boolean mask. Wire a comparison node into the mask and you've got conditional data flow.

Editor Polish, Round One
Proper z-ordering, smarter tooltips, a disappearing inspector, search that opens where you're looking, and a theme system that replaces every magic number.

Every Node, Documented
110 nodes and 203 pins now carry structured documentation — summaries, descriptions, tags, cross-references, and per-pin help text — all the way from source code to the editor UI and a machine-readable JSON export.

42 Math and Logic Nodes
Add, Subtract, Multiply, Divide, Sin, Cos, Lerp, SmoothStep, Map, and 33 more. Polymorphic, type-preserving, NaN-safe.

Animation: Timing Nodes
Timer, Metro, Delay, Debounce, Throttle, OnChange. When things happen matters as much as what happens.

Animation: Damper, Spring, and Easing
Raw data is jagged. These nodes make everything smooth, bouncy, or shaped exactly how you want.

Animation: LFO, Phasor, and Pulse
The heartbeat of any patch. Three oscillator nodes that make things move.

Zero-Allocation Evaluation
I tore apart the eval loop and rebuilt it. Pre-allocated buffers, cached adjacency maps, borrowed NodeInfo. No allocations in the hot path.

Spreads: The Core of Lux
What if you never wrote a loop again? One wire carries [10, 20, 30, 40, 50]. Every node downstream evaluates per-element automatically.
