Radeon Raytracing Analyzer

Visualize.

Analyze.

Optimize.

Available as part of the Radeon™ Developer Tool Suite.

RRA BLAS

Meet the Radeon™ Raytracing Analyzer (RRA) tool. Investigate the performance of your raytracing applications and highlight potential bottlenecks.

Download now - v1.0

Initial release: 

  • Visualize bounding volume hierarchies (BVHs).
  • Show BVH memory usage, instance and triangle counts, and a whole host of other useful statistics.
  • Analyze the application environment, using different rendering and coloring modes.

Benefits

By using either geometry mode or traversal mode in addition to a selection of coloring modes, RRA allows you to easily spot areas of interest in your scene that need optimizing.

RRA generates easy to understand visualizations of how your DirectX®12 and Vulkan® ray-tracing applications can be optimized. As with all the tools, capturing the ray-tracing content of a game is both quick and simple, using the Radeon™ Developer Panel and our public GPU driver.

Assess your acceleration structures

Get a high level view of your acceleration structures.

See how many TLAS and BLAS objects you are using, how large the acceleration structures are, and how much memory they are consuming.

Visualize the scene

Use the TLAS viewer to visually inspect your scene. Select from a number of coloring modes to highlight areas of interest. See opaque/non-opaque geometry at a glance and a host of other parameters.

Some coloring modes use a range of colors in a heatmap (the surface area heuristic modes, for example) making it easy to see hotspots.

Review your ray traversals

Switch to the traversal counter rendering mode to see how rays interact with your scene.

The heapmap image will show areas that require attention. Generally the more red an area, the greater the counter number. The counter types can be selected to show instance hit, box hit/miss, triangle hit/miss and more.

Inspect those instances

A list of all of the instance in the TLAS is available. A separate table is available for instances of a particular BLAS.

Blast through your BLASes

Here, you can see high level statistics for every BLAS in your scene, including things such as memory usage and triangle counts.

All the tables in RRA, like the other tools, have column sorting and text searching so it’s easy to find what you’re looking for.

Double-clicking on a BLAS will display it in the BLAS viewer, almost identical to the TLAS viewer but allows inspection of a single BLAS.
