grass_02

This article describes the data/samples/objects/grass_02.cpp sample.

The grass_02 sample demonstrates how to place the grass on the terrain according to an image 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 image mask according to which the grass is placed

Grass placed upon the terrain according to the image mask
