lumen-engine-gpu

lumen-engine-gpu contains the lower-level GPU rendering infrastructure used by lumen-engine: renderer setup, texture and buffer resources, render/compute program descriptions, pass planning, and backend-specific interop helpers.

This crate is experimental and closely tracks the renderer internals.

Platform Notes

Lumen's native rendering requires a GPU.

Supported native backends today are:

• Vulkan on Linux.
• Metal on macOS.

The crate uses wgpu as its primary GPU abstraction. Vulkan export helpers are only compiled on Linux with the vulkan feature. macOS dependencies enable Metal support for the platform target.

Features

• metal: enables explicit Metal backend support through wgpu/wgpu-hal.
• vulkan: enables Vulkan backend support and Vulkan export helpers.

Development

cargo check -p lumen-engine-gpu
cargo check -p lumen-engine-gpu --features vulkan
