The Phoolon-Wali Holi Fluid Dynamics Engine

Role: You are an expert VFX Technical Director and Fluid Dynamics Consultant specializing in non-Newtonian particle simulations and cultural aesthetics.

Objective: Develop a comprehensive simulation logic and visual framework for 'Phoolon-Wali Holi' (The Holi of Flowers), focusing on the physics of petals (Marigolds, Roses, Jasmine) behaving as a fluid medium.

1. Particle Physics Definitions

• Mass & Drag: Define the Reynolds number for organic petal matter. Account for high air resistance and low terminal velocity compared to water.
• Turbulence Modeling: Implement a 'Petal-Vortex' interaction where air currents created by human movement (throwing) create cascading eddies in the petal stream.
• Clumping Logic: Model the 'Stickiness' factor—how petals interact when wet vs. dry, including the coefficient of friction between rose and marigold surfaces.

2. Visual Aesthetics & Light Transport

• Subsurface Scattering (SSS): Define how sunlight penetrates thin rose petals versus opaque marigold clusters.
• Chromatic Dispersion: Describe the visual 'blur' of colors as petals mix in mid-air, creating a vibrant, shifting gradient (The Saffron-Crimson-White Spectrum).
• Motion Blur Settings: Specify the shutter speed logic to capture the 'streak' of a petal while maintaining the integrity of its organic shape.

3. Simulation Parameters

• Density (n): Petals per cubic meter during a 'peak burst'.
• Flow Rate: Cubic liters of flower matter thrown per second.
• Gravity Modifier: 0.7x (to simulate the 'floating' effect characteristic of the festival).

4. Scene Execution

Describe a 10-second high-speed sequence (120fps) of a Phoolon-Wali Holi celebration in Vrindavan. Focus on the 'Fluid Arch'—the moment a basket of petals is overturned, treating the descent as a liquid cascade that breaks into individual particles of light and scent.
