This object is intended to be used as a relatively cheap memory hint to the hardware ray-tracing pipeline to attempt to cut down on the number of times the expensive <code>AnyHit</code> shader has to be called. </p> <p> It may still be relatively big however; so in this work we introduce a way to interpret the micromap as a tree structure that in turn can be compressed in a very efficient way: Up to 110 times in some actual content. </p> <p> You can find the presentation, the slides, and the paper itself among my <a href="/pages/publications/">publications</a>. </p>micromapsray tracingtexturesVulkanhttps://gustafwaldemarson.com/posts/succinct-opacity-micromaps/Sun, 18 Aug 2024 10:58:18 GMT
