#include <lib_hair.h>

详细描述

◆ Alloc()

static HairCollider * Alloc

(

)

static

Allocates a hair collider. Destroy the allocated hair collider with Free() 。使用 AutoAlloc to automate the allocation and destruction based on scope.

返回: The allocated hair collider, or nullptr if the allocation failed.

◆ Free()

static void Free

(

HairCollider *&

)

static

Destructs hair colliders allocated with Alloc() 。使用 AutoAlloc to automate the allocation and destruction based on scope.

参数

[in,out]

The hair collider to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards.

◆ Init()

Bool Init

(

HairGuides *

hair

)

Initializes the hair collider.

参数

[in]

hair

The hair to initialize with.

返回: true if successful, otherwise false .

◆ Release()

void Release

(

)

Releases allocated memory. Called automatically by Free() .

◆ GetClosestPoint()

Int32 GetClosestPoint

(

const 向量 &

)

Gets the closest point to p .

参数

[in]

The point to search for.

返回: The closest point or NOTOK if an error occurred.

◆ GetClosestSegment()

Bool GetClosestSegment	(	const 向量 &	p ,
		Int32 *	guide ,
		Int32 *	segment ,
		Float *	segt
	)

Gets the closest segment to p .

参数

[in]	p	The point to search for.
[out]	guide	Assigned the guide index.
[out]	segment	Assigned the segment index.
[out]	segt	Assigned the segment t coordinate.

返回: true if successful, otherwise false .

◆ GetParticleIntersection()

Bool GetParticleIntersection	(	const 向量 &	p ,
		const 向量 &	v ,
		Float	r ,
		Int32 *	guide ,
		Int32 *	segment ,
		Float *	segt ,
		Float *	rayt
	)

Gets the intersection of particle p with vector v , looking within a distance radius of r .

参数

[in]	p	The point to search for.
[in]	v	The vector of particle to search for.
[in]	r	The search distance radius.
[out]	guide	Assigned the guide index.
[out]	segment	Assigned the segment index.
[out]	segt	Assigned the segment t coordinate.
[out]	rayt	Assigned the ray coordinate.

返回: true if successful, otherwise false .
