Microtome

GPU-accelerated model slicer for DLP-style resin 3D printers. Generates black-and-white bitmap slice images using wgpu compute and render pipelines.

Features

• Fast GPU slicing via wgpu (intersection-test / slice-extract two-pass algorithm)
• 3D viewport with Phong-shaded mesh rendering, orbit camera, and transform gizmos
• Real-time slice preview with overlay visualization
• STL file loading with automatic winding order correction
• Batch export to ZIP archives of PNG slice images
• Handles overlapping and self-intersecting geometry without boolean pre-processing

Building

Requires Rust 1.85+ and a GPU with Vulkan, Metal, or DX12 support.

cargo build --release
cargo run --release
