grass_03

This article describes the data/samples/objects/grass_03.cpp sample.

The grass_03 sample demonstrates how to place the grass on the terrain according to a mesh mask, namely:

• Load the terrain
• Add the grass to the editor and make it a child node of the terrain
  Notice

  It is also required to enable intersection with parent objects to make the grass grow upon the terrain.
• 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
