Description
Small tech demo created in 2013 showcasing a variety of features.
The goal is simply to find & click as many bugs as possible.
Grass Shader description
As most games implement basic grass vegetation as a single plane, I felt that experimenting with a different approaches was an interesting topic for a geometry shader.
The framework passes only a single vertex to the shader, which respresents the position of a single grass blade.
Grass blades consist of 1 to 5 planes in height (depending on the lod) and have the ability to wave with the wind (both simulated & generated by an object).
Even tough it's a fairly inefficient way of rendering large patches of grass, it has a unique look & feel to it.
