This thesis presents the design and implementation of a GPU-based ray tracer capable of rendering NVIDIA's micro-meshes. The method operates entirely in two dimensions by projecting both rays and triangles onto a 2D domain. Within this domain, the projected ray traverses the micro-triangles, starting at subdivision level 0. The triangles are then recursively subdivided until the finest subdivision level is reached, at which point the micro-triangle intersected by the original 3D ray is identified. To accelerate traversal, the approach employs height field ray tracing, which restricts subdivision to regions where it is strictly necessary. In addition, the proposed method demonstrates a reduced memory footprint compared to traditional ray tracing, while maintaining acceptable runtime performance. Memory savings of up to approximately 50% are achieved relative to a fully tessellated representation.

Continuous Integration (CI) systems automate the building, testing, and possibly more. However, it is still unclear how CI should be implemented in different contexts. Therefore, this paper tries to answer the question "What metrics can be used to describe project activity", as part of a bigger study. We mined information from 500 repositories and then applied several analysis techniques to find out whether a metric can be used to describe activity or not. Among the results, we show that the activity around a release date increases, and that Java is a way more active language than other languages, with the highest amount of commits, closed pull requests, contributors, issues, and releases.
