# RenderKit

Yet another Metal Rendering engine experiment…

## Assumptions

Post-multiplication, Column-Major, Right-handed, Y up

## Screenshots

## Goals

### Longer Term

* Tie into WASD/Game Controller system (from RenderKit - move code to Everything)

* Render the position of lights

* Learn from [RenderKit2](https://github.com/schwa/RenderKit/tree/RenderKit2) & [RenderKitClassic](https://github.com/schwa/RenderKit/tree/RenderKitClassic)

* More type-safety. Especially pipeline attributes

* Async. (Good luck)

* Outputs

  * A unified "renderable" system. Can render to any of multiple locations - MTKView, "raw" CAMetalLayer, offscreen textures, VistionKit immersive spaces etc.

  * ~~Built-in offscreen renderer~~ (Working but API can be fixed)

  * Built-in support for ~~MTKView~~ and CAMetalLayer

  * VisionKit 'CPSceneSessionRoleImmersiveSpaceApplication' output

  * (The more outputs the less fragile the APO will be)

* Simpler API for just getting shit on-screen

  * Create a simple render API that takes a single pipeline

* RenderEnvironment variables modelled after SwiftUI.Environment for safety

* Use Function-builder for pipelines/stages etc

* Cleaner render model that more closely matches Metal.

* Built-in support for RenderGraph editor (use NodeEditor)

* Work with multi-sample, ray tracing

* Figure out how to #include metal headers across packages (likely not possible).

* Get more helper code of RenderKit and into MetalSupport etc

* Use Spatial framework

  * Use the shape code from Spatial to bring in a `shape3d` type that can export MTKMeshes* Simple SwiftUI Canvas style line drawing mode.

  * Some of the rotation code here may be useful - what else is new in Spatial?

* Bring over my Projection package (3d vector graphics)

* Take advantage of Swift macros (macro to encode struct into a buffer compatible with SwiftUI)

* Sort out the various projection APIs
