[RELEASED]Large-scale grass rendering For Mobile ---- High-performance

Very early gpu gems series books have been introduced to the rendering of large-scale grass, although the technology inside is old but very practical.

I made a certain modification on the basis of their description, by increasing the vertices without using any alpha test, and reducing the use of the billboard through the intersection of a super large grid.

In addition, I have added additional interactive features that require OpenGL 3.0 support. You can see that when the ball moves, the grass will fall in the right direction. I drew a love through the ball.

The entire grassland can still have excellent performance on mobile phones.

have a look

 

How big / large can we make the grass area?
can we mix different grass types?
How do you control the density of the grass? Any random heights?
Can you show more on how the asset is set up?
What kind of lighting does the grass have? Shadows?
