Blade

Blade grass is the procedural representation. Its controls are about individual blade geometry, natural starting shape and surface detail.

Shape

bladeWidth and bladeHeight control the dimensions of each rendered grass element. bladeStiffness controls rigidity; when a blade bends, stiffness also affects the visible creases/partitions in the geometry.

Initial bend

baseBend adds a natural bend before wind or interaction. baseBendScale controls the distribution and directional variation of that initial bend: lower values make the bend more consistent, while higher values introduce more directional variation.

js
grassworks.setGrassParams({
  bladeWidth: 0.12,
  bladeHeight: 2.4,
  bladeStiffness: 1.1,
  baseBend: 0.3,
  baseBendScale: 1.2
});

Blade texture

useBladeTexture can add extra texture detail while keeping the shader-generated base, tip and variation colors active. It is not a replacement for the color system.
