lib-composit
Comp's operators and their GPU executor, beside Kinogaki Studio's Comp plugin (which holds the node types and compiles a network to a plan): plans of steps that turn a render engine's images (the beauty and its outputs, linear ACEScg, premultiplied, at each step's own size) and image files into what a view shows or a final render writes. It runs on the GPU, on the host's own wgpu device (wgpu 30, Studio's version). The crate docs describe what exists.
| Crate | Role |
|---|---|
kinogaki-composit (crates/composit) | No device: each operator's parameters decoded for the GPU and its maths on one pixel (the CPU reference), tone curves, and the plan a host compiles a network to |
kinogaki-composit-wgpu (crates/wgpu) | The executor: a plan's steps as compute passes encoded into the host's encoder, pooled step textures, reruns only what changed |
Module (kinogaki-composit) | Role |
|---|---|
curve | Tone curves (monotone cubic or straight keys from 0 to 1) and ACEScct's log shaper for curves on scene light |
image | Images on the CPU, which the spatial operators' references read and write |
nodes | Levels, Curves, Grade, Hue / Saturation (OkLCh), Blur, Bloom and Merge: each operator's decoded parameters and its maths (the CPU reference) |
plan | Steps in order, each an operator over the images it reads, the last's image what the plan shows; only values, so a host compares two plans' steps to know what changed |
Module (kinogaki-composit-wgpu) | Role |
|---|---|
executor | Executor::run: a plan on the images a host lends it (Images: the render's outputs and the image files) into the host's encoder, giving the image it shows (Shown) |
kernels | Compute kernels (WGSL in kernels/shaders, shared pieces such as oklab.wgsl put first), each listing its bindings; compiled when first needed |
work | A step's passes, uniforms and scratch (Blur's half-blurred image, Bloom's levels, Curves' table), rebuilt only when its shape, inputs or size change |
pool | Rgba16Float textures: each step's output, and the textures hosts hold an image's pixels in |
Siblings
It reaches sibling checkouts as the Kinogaki Studio tree has them under libs/: ../lib-color (the matrices and Oklab the CPU references use), ../lib-ui and ../lib-misc-utils (the frozen crates the patch table names).
