Evaluate Opacity Micromaps for ray-traced game assets

Who is this for?

This Learning Path is for game graphics developers who need to evaluate whether an alpha-tested asset is suitable for Opacity Micromaps (OMM) on Arm Mali G2-Ultra NX. You can complete the Learning Path without OMM-capable hardware.

What will you learn?

After completing this Learning Path, you'll be able to perform the following tasks:

• Classify microtriangles as opaque, transparent, or unknown from alpha-mask data.
• Trace OMM data from baking through acceleration-structure traversal.
• Choose an OMM format, subdivision strategy, fallback, and validation plan for an asset.
• Identify the Vulkan enablement requirements for ray pipelines and ray queries.

Prerequisites

Before starting, you'll need the following prerequisites:

• Basic familiarity with triangle geometry and alpha-tested materials
• Basic familiarity with ray tracing intersections and acceleration structures
• (Optional) An Arm Mali G2-Ultra NX device and Vulkan capability tools for device validation
