|The grass blades are the purple dots everywhere|
They are barebone though - they don't have any texture. Nevertheless, they do have a pretty decent mesh. The mesh for these grass strands are inspired by this picture from Markus R. Tillman's bachelor's thesis on DIVA (link here). The figure below is a screenshot of the illustration made by Per Axmark which my implementation attempts to recreate.
In my project, however, I only create the highest level of detail grass blade. There are three different ways the grass blade geometry can vary.
- The width of the grass blade.
- The height of the grass blade.
- The inclination of the grass blade.
