详细描述

GLSL compute kernels for the GPU surface-flow solver.

GLSL compute kernels for screen-space fluid surface reconstruction.

CPU reference fluid solver for surface flows.

Voxelized signed distance field (SDF) of a solid surface.

Core math shared by the CPU reference solver and the GLSL kernels.

The kernels mirror FluidSimulation.cpp 1:1. Push-constant layout (float[32]):

FluidMath holds the SPH kernel functions (poly6 / spiky gradient / viscosity Laplacian), the tuning parameters and the particle layout used by both the reference implementation in FluidSimulation and the GPU kernels in FluidGpuKernels. Keep the two in step: every formula here is mirrored 1:1 in GLSL, and the push-constant layout is documented in FluidGpuKernels.h.

The mesh is baked into a uniform 3D grid once at setup; particles then query distance + gradient per frame in the GPU kernels (trilinear interpolation, central differences) to stay glued to the surface while gravity pushes them tangentially along it. Positive distance = outside the solid.

This is the executable spec for the GPU kernels in FluidGpuKernels: uniform grid neighbor search, SPH density, PBF density constraints, XSPH viscosity, Akinci-style cohesion/adhesion, gravity, surface projection through the mesh SDF and velocity decomposition. Tests exercise it numerically; the GLSL kernels mirror it 1:1.

Pipeline (mirrors FluidSurfaceRenderer.cpp): clear -> splat (particles to depth+thickness) -> smooth (bilateral, ping-pong) -> normals (depth gradients) -> shade (water or mud).

◆ buildVolumeFluidCubeDistribution()

EVENGINE_API_DOMAINS Result< std::vector< VolumeFluidDistributionPoint > > eve::fluids::buildVolumeFluidCubeDistribution	(	glm::vec3	size,
		float	spacing,
		bool	surface
	)

Builds an Fluid3D-compatible box surface or volume lattice during setup.

size is the full local box size. Surface points emit along the normalized sum of their incident face normals; volume points emit along local +Z. Candidate and output counts are limited to 65536 and 4096; failure returns no partial distribution.

		float	spacing,
		bool	edgeEmission
	)

Builds Fluid3D's concentric disk or circumference-only distribution.

Radius/spacing must be finite and positive. Edge samples emit along their radial normal; filled-disk samples emit along local +Z. Setup-time only, owning, with 65536 candidate and 4096 output limits.

		float	spacing,
		float	radialVelocityDegrees
	)

Builds Fluid3D's edge lattice with per-sample radial velocity directions.

length is the full local X extent. Samples use spacing plus Fluid3D's 0.01 metre separation bias; radialVelocityDegrees rotates local +Z around X for each successive sample. Setup-time only, owning, and limited to 4096 points.

◆ buildVolumeFluidImageDistribution()

		unsigned	width,
		unsigned	height,
		float	pixelScale,
		float	maximumSize,
		float	spacing,
		float	alphaThreshold
	)

Precomputes a bilinear alpha-masked image distribution on a spacing lattice.

Pixels are linear RGBA, bottom row first. No image pointers are retained. Aspect ratio is preserved when clamping world dimensions to maximumSize. At most 65536 lattice candidates and 4096 output points are allowed; excess returns a diagnostic without partial output. Call during authoring/setup.

		glm::vec3	scale,
		float	spacing
	)

Voxelizes indexed triangles, returning surface and enclosed interior cell centers.

Setup-time only, owns its result and retains no mesh pointers. Scaled bounds determine voxel size, at least spacing and at least longest extent/32. Open meshes produce surface cells without assuming an enclosed interior. Limits: 65536 triangles, 4M cell/triangle checks, 4096 output samples; exceeding any budget returns a diagnostic rather than a partial distribution.

◆ composeVolumeFluidEmitterShapes()

EVENGINE_API_DOMAINS Result< VolumeFluidEmission > eve::fluids::composeVolumeFluidEmitterShapes	(	const VolumeFluidEmission &	base,
		std::span< const VolumeFluidEmission >	shapes
	)

Builds one emitter distribution from an ordered set of Fluid3D emitter shapes.

base owns emitter-wide material, speed, lifetime, filter and RNG settings. Each shape must be a Distribution description; its pose transforms its owned local samples into solver space. An empty shape contributes its pose origin/direction, and an empty shape list contributes the base pose, matching Fluid3DEmitter's default point behavior. The setup-time operation accepts at most 64 shapes and 4096 total samples, publishes no partial result, retains no input storage and adds no per-step allocation or GPU work. Same ordered inputs produce the same ordered distribution on the same build. Simulation-thread affinity applies when the returned value is later used by an emitter; this pure composition call itself touches no solver and invokes no callbacks.

参数

base	Borrowed emitter-wide description, copied into the returned owning value.
shapes	Borrowed ordered shape descriptions, valid only for this synchronous call.

返回: Owning combined Distribution description, or a structured validation diagnostic.

Atomically maps every Fluid3DEmitterBlueprint field to native 3D setup values.

Pure setup-time operation. The returned solver settings and emission description own all data; no solver, callback, render resource or GPU work is created. The default shared-solver capacity equals the actor blueprint capacity and may be increased before solver construction.

◆ prepareVolumeGranularEmitterBlueprint3D()

EVENGINE_API_DOMAINS Result< VolumeFluidEmitterBlueprintApplication3D > eve::fluids::prepareVolumeGranularEmitterBlueprint3D ( const VolumeGranularEmitterBlueprint3D & blueprint )

Atomically maps an Fluid3DGranularEmitterBlueprint to owned native 3D setup values.

Pure setup-time operation. Radius variation uses the existing seeded emission stream; no global RNG, solver, render resource or GPU work is created by this call.
