Geometry Nodes: The Key to Procedural Animation
Geometry Nodes have revolutionized the way artists work in Blender, enabling procedural modeling and animation with unprecedented flexibility. Cinematic Cookie’s tutorial leverages this power to create a realistic and engaging paint brush effect. The core idea is to use Geometry Nodes to control the deformation and movement of the brush and bristles, simulating the act of painting.
Here’s a glimpse into the process:
- Base Mesh Creation: Start with a basic model of a paint brush.
- Geometry Nodes Setup: Use Geometry Nodes to distribute points along the brush’s path.
- Bristle Generation: Instance bristles onto these points, controlling their length, thickness, and orientation.
- Animation: Animate the points to simulate the brush strokes, creating a dynamic painting effect.
