Water Global

The Water Global samples demonstrate how to control Global Water via API:

This sample demonstrates how to control the wave spectrum of Global Water in Manual mode via API over wave parameters (octaves - a set of waves at a specific size/frequency level, count per octave, length, amplitude, phase, and steepness).

Because all wave parameters are managed on the CPU side, they can be dynamically generated, modified, or stored for reproducible results and external integration (for example, to process Weather Control packets from IOS).

This sample demonstrates how various parameters influence the accuracy of fetch (sampling water height and normal) and intersection (ray-water collision detection) operations on the Global Water object across different Beaufort levels (the Beaufort slider).

You can interactively adjust the following parameters:

• Steepness Quality: Controls wave detail resolution used in sampling.
• Amplitude Threshold: Filters out minor waves to improve performance at the cost of detail.
• Precision: Controls ray-water intersection accuracy. Lower values reduce jitter when intersecting at an angle.
• Intersection Angle: Adjusts the incoming ray direction for intersection tests, helping evaluate how steep angles affect detection stability.

The UI also allows you to:

• Select between Fetch and Intersection modes
• Show or hide normals at the sampled points
• Adjust the number of samples and visual point size

This sample is useful for fine-tuning water interaction accuracy in physics, gameplay, and visual effects - especially when working with sloped or moving viewpoints (e.g., cameras, characters, or objects interacting with water).
