This was an experiment I recently finished and I think it turned out quite nice.
The grass you see is a particle system. All of the particles are the same diffuse color, and I didn’t use modeled geometry for the grass blades. I mainly did this to see how realistic I could make the result without the aid of detailed grass strands.
Like real mown grass, each row and column is pushed slightly in one direction. Since this grass is mowed in the X and Y directions, you get four different sections, each with a different [X,Y] combination. Here’s a diagram I drew when testing to help you understand.
I made each section have a different angle by adjusting the particle system’s settings.
