The EuroCG just finished today. I already posted about day 1, so here is the second part. Don't forget that all abstracts are available for download.

## Day 2

The second day also had some very nice talks. Probably the talk I was looking most forward to was the talk of **Stefan Felsner **about *"Exploiting Air Pressure to Map Floorplans on Point Sets". *A floorplan is a dissection of a rectangle into smaller rectangles. All rectangles are axis aligned. The floorplan is realized on a point set, if every segment contains exactly one point of the point set. Stefan showed that for every floorplan, you can find a realization of an equivalent floorplan on every point set in general position. This is not only a nice result, Stefan used also some cool tools to prove it.

Another talk I liked was given by **Nieke Aerts** about *"Straight Line Triangle Representation"* (joint work with Stefan Felsner). Nieke talked about the following problem: Can I draw a planar graph, such that every face has the form of a triangle? To realize such drawings many vertices have to be adjacent to an angle of exactly 180°. The talk was about necessary and sufficient conditions that such drawings exist. There are still many open questions left. This problem seems related to the stretchability of combinatorial pseudo-triangulations, but the straight line triangle representations are more difficult to understand - at least for now.

The second invited talk was given by **James McLurkin. **James talked about geometric challenges in multi-robot systems and showed many nice videos.
