详细描述

Flowing waterfall (falling water sheet) rendered on a vertical plane.

A custom Mesh3D fragment shader renders a vertical XY plane (facing +Z) as falling water:

Water rushes downward, driven by a scrolling noise + layered sine streaks so the surface reads as a tumbling cascade rather than a flat plane.
Animated foam/white-crest band at the top lip (water spilling over) and a turbulent splash zone at the bottom where the sheet hits the pool.
Vertical velocity streaks stretch in the fall direction to sell the motion.
Reflects the sky via the environment cubemap (binding 3), Fresnel-weighted, plus a specular glint from the primary directional light.

Parameters are packed into the shader push-constant block (data[0..31]); see Waterfall::bindParams for the layout. Caller owns Waterfall*; its Mesh / Shader are owned by Graphics.
