Closed pomadchin closed 4 years ago

pomadchin commented 4 years ago

This PR adds a benchmark project that compares DEMRasterSource that uses PDAL triangulation and that uses GeoTrellis triangulation.

This PR also benchmarks a split of PDALTrianglesRasterizer into a separate object, the results are below

/**
