| Parameter | Description |
|---|---|
| bakeInput | Scene data extracted using ExtractFromScene. |
| progress | Progress tracking object for monitoring world population status. |
| context | Device context that will be used for light transport calculations. |
| world | World object to populate with the processed scene data. |
bool True if world population completed successfully, false if errors occurred.
Converts extracted scene data into optimized data structures for light transport calculations.
This method transforms the raw scene data from BakeInput into optimized data structures suitable for ray tracing and light integration. The process includes:
Data Processing:
Device Compatibility:
The populated world is optimized for the specific device context:
- GPU contexts: Data uploaded to GPU memory with optimized layouts.
- CPU contexts: Data organized for SIMD processing and cache efficiency.
Performance Impact:
This operation can take significant time for complex scenes as it involves:
- Geometry preprocessing and optimization.
- Memory allocations and data transfers.
- Acceleration structure construction.
- Shader compilation (on first use).
The populated world can be reused across multiple integrators for efficiency.
// Complete workflow: extract scene data and populate world bool extractResult = InputExtraction.ExtractFromScene(out var bakeInput); Assert.IsTrue(extractResult, "Scene extraction failed");
// Create device context and world using var context = new RadeonRaysContext(); bool initResult = context.Initialize(); Assert.IsTrue(initResult, "Failed to initialize RadeonRays context");
var world = new RadeonRaysWorld();
// Set up progress monitoring using var progress = new BakeProgressState(); progress.SetTotalWorkSteps(1000); // Estimate based on scene complexity
// Populate world with extracted data bool populateResult = InputExtraction.PopulateWorld(bakeInput, progress, context, world);
if (!populateResult) { Debug.LogError("Failed to populate world with scene data"); return; }
// World is now ready for integration operations var integrator = new RadeonRaysProbeIntegrator(); integrator.Prepare(context, world, probePositions, 0.1f, 2);
// Proceed with lighting calculations var result = integrator.IntegrateDirectRadiance(context, 0, probeCount, 1024, false, outputBuffer);
