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 heat map 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 AMD 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.

Reveal your ray dispatches

Starting with v1.3, AMD RRA now gives you the ability to see individual rays and how they interact with the scene, showing intersections, misses and the shaders called on those rays, including additional rays generated from the initial ray.

Select a “pixel” from the table or heatmap ..

.. and see the rays that are shot from that pixel.
