Project Overview

Interactive Grass & Plant

Grass: I mainly used vertex offset to realize grass offset by calculating the direction from player to each vertex.

Plant: I used render target to get record the position of the player add a attenuation to it's vertex offset to make it looks more realistic.

Wind: Add a global vertex offset by using noise.

I used two render target, first one to draw foot prints, second one to record previous foot prints, so that the brush area could always follow the player and will not affect previous render target position.
