grass_01

This article describes the data/samples/objects/grass_01.cpp sample.

The grass_01 sample demonstrates how to place the grass according to a mesh mask, namely:

• Add the grass to the editor
• Set a transformation matrix and assign a material to make the grass visible in the scene
• Specify the required options: maximum visible and fade distances, width and height, step for cells used to render grass, density factor, etc.
• Set the mesh-based mask to specify the areas where the grass should grow
