Detailed Description

Owns a headless WebGPU device/queue pair for GPU rendering.

GeodeDevice is the entry point to the Geode rendering backend. It creates a Dawn instance, selects a default adapter, and creates a device — all without any window system integration. All rendering happens into offscreen textures.

Typical usage:

auto maybeDevice = GeodeDevice::CreateHeadless();
if (!maybeDevice) {
  // Dawn initialization failed — likely no GPU available.
  return;
}
GeodeDevice& device = *maybeDevice;
wgpu::Texture target = device.device().CreateTexture(...);
// ... render ...

CreateHeadless()

std::unique_ptr< GeodeDevice > donner::geode::GeodeDevice::CreateHeadless ( )

static

Create a headless GeodeDevice.

Returns

A valid GeodeDevice on success, or an empty unique_ptr if Dawn could not create an adapter/device (e.g., no GPU, no driver).
