详细描述

Borrowed 2D signed-distance field consumed by particle collision.

Negative samples are inside the solid. Providers live in higher modules (physics, fluids, gameplay) and register through capability wiring; the particles module only samples this interface and never includes provider headers.

@ownership Borrowed for the duration of the emitter binding. Callers must clear the binding before destroying the field. @thread Owner thread only; not reentrant from particle callbacks.

构造及析构函数说明

◆ ~IParticleSdfField()

virtual eve::IParticleSdfField::~IParticleSdfField ( )

virtualdefault

I particle sdf field.

成员函数说明

◆ gradient()

virtual ParticleSdfGradientStatus eve::IParticleSdfField::gradient	(	float	x,
		float	y,
		float &	outNx,
		float &	outNy
	)		const

pure virtual

Approximate outward unit gradient at a world-space position.

参数

[out]	outNx	X component of the unit gradient when the status is Defined.
[out]	outNy	Y component of the unit gradient when the status is Defined.

返回: Defined when a finite gradient was written; Undefined at empty fields or singularities.

被这些函数引用 eve::particles::stepEmitterSim().

◆ sample()

virtual float eve::IParticleSdfField::sample	(	float	x,
		float	y
	)		const

pure virtual

Sample signed distance at a world-space particle position.

返回: Finite signed distance in world units, or +inf when unsupported.

被这些函数引用 eve::particles::stepEmitterSim().
