org.das2.graph.PolyMeshRenderer

render a 2-D poly (typically triangle) mesh. This was introduced just to identify this schema. This renderer needs rank 3 data with 2 bundled datasets, the points in X-Y data space and the triangles (or polys) which connect them. When a rank 1 dataset with a triangleMesh as DEPEND_0 is passed in, then colors or text will be drawn. Note, QDataSet should not support a join of non-qube datasets, so all polygons should have the same length (all triangles or all four-sided polys). Most codes will work fine if this is not the case. Applications for this include marking data and drawing tesselations.
