MTK

MTK is now a core-only Swift package for medical volume rendering. It ships:

• MTKCore for volume data, Metal rendering, presentation passes, export, and MPR/transfer-function primitives.
• MTKFixtures for reusable test and rendering fixtures.

Screenshots

What is included

• VolumeDataset as the stable input contract
• Metal-native rendering, MTLTexture frames, PresentationPass, and MPRPresentationPass
• CGImage export and snapshot/readback helpers
• Transfer functions, volume pipeline helpers, and clinical geometry/picking
• Loaders and adapters that stay inside the core rendering contract

What is not included

• No shipped product UI module
• No demo app
• No SwiftUI, UIKit, or AppKit product surface
• No external bridge package

Installation

dependencies: [
    .package(url: "https://github.com/ThalesMMS/MTK.git", from: "1.0.0")
]

Then depend on:

.product(name: "MTKCore", package: "MTK")
.product(name: "MTKFixtures", package: "MTK")

Core flow

The package contract ends at frames and textures:

VolumeDataset -> loader/transform -> GPU textures -> render passes -> PresentationPass / MPRPresentationPass -> MTLTexture or explicit CGImage export.

Testing

cd MTK && swift build
cd MTK && swift test
cd MTK && swift build -c release
