Vulkan Grass Rendering

Features

• Represent grass as Bezier curves

  

• Simulate forces with gravity, recovery and wind.

  

• Cull the blade when the front face direction is perpendicular to the view vector and when blades are outside of the view-frustum.

• Tessellate to varying levels of detail as a function of how far the grass blade is from the camera.
