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
- 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
Grass placed upon the terrain according to the mesh-based mask
In this sample, the samples/objects/meshes/grass_01.mesh planar mesh is used as the mask.
