How We Do Stuff: Building a Bigger Better World

We also managed to increase the tessellation density (a process of dividing polygons into smaller parts in 3D graphics) of our rendering system by about 30% compared to the default values right out of the box. It made the spines and apexes of hills and mountains look much sharper.

The terrain render optimization let us pick out all relevant texture combinations and integrate them into batches, which resulted in a significant render productivity increase.
We’ve also added a light map for trees and other static objects. Thus, trees in the shade do not glow and give no flecks—they only get indirect lighting; objects placed in the sunlight are lit by the direct and indirect light.

In the coming weeks, expect to hear more about cloud schemes, battling arenas, and water surface rendering. Hope you enjoyed the reading.
