Description:
Create offline tool to generate the specific noise textures required by Horizon paper: Perlin-Worley, Worley, and Curl noise.
Tasks:

Research Perlin-Worley noise generation
Create offline noise generation tool (separate binary)
Implement 3D Perlin noise generation
Implement 3D Worley noise generation
Combine Perlin and Worley (Perlin-Worley)
Generate 128³ 4-channel texture (base shape)
Generate 32³ 3-channel texture (detail erosion)
Implement 2D Curl noise generation
Generate 128² 3-channel texture (turbulence)
Save textures in appropriate format (DDS or raw)
Load textures into engine as 3D textures

Acceptance Criteria:

Can generate all required noise textures
Textures tile seamlessly
3D texture loading works in Vulkan
File sizes reasonable (compressed if possible)

Related Issues: None
Resources:

CloudNoiseGen Unity example
The Book of Shaders noise section
GPU Gems 2 Chapter 26

Estimated Time: 4-5 days
