详细描述

Collision cache : stores a set of triangles, each with an ID, for use with the other collision classes.

注意: Has to be created with Alloc() and destroyed with Free() 。使用 AutoAlloc to automate the allocation and destruction based on scope.

The following function fills a GeColliderCache from a BaseObject :

Bool FillColliderCache( GeColliderCache & c, BaseObject & obj) { // Get polygon object ModelingCommandData md1; md1. op = &obj; md1. doc = obj. GetDocument (); if (! SendModelingCommand ( MCOMMAND_CURRENTSTATETOOBJECT , md1)) return false ;

// Triangulate it ModelingCommandData md2; md2. op = static_cast< BaseObject * > (md1. result -> GetIndex (0)); if (! SendModelingCommand ( MCOMMAND_TRIANGULATE , md2)) return false ; AutoAlloc<PolygonObject> poly( static_cast< PolygonObject * > (md2. op )); if (!poly) return false ;

// Get the polygon data CPolygon * tris = poly->GetPolygon(); 向量 * points = poly-> GetPoint ();

// Fill the cache

if (c. BeginInput (poly->GetPolygonCount()) != COL_OK ) return false ;

for ( int i = 0; i < poly->GetPolygonCount(); ++i) { if (c. AddTriangle (points[tris[i].a], points[tris[i].b], points[tris[i].c], i) != COL_OK ) return false ; } if (c. EndInput () != COL_OK ) return false ; return true ; }

◆ Alloc()

static GeColliderCache * Alloc

(

)

static

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

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

◆ Free()

static void Free

(

GeColliderCache *&

data

)

static

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

参数

[in,out]

data

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

◆ CopyTo()

Bool CopyTo

(

GeColliderCache *

dest

)

Copies all triangles to another cache.

参数

[in,out]

dest

The destination cache. The caller owns the pointed collider cache.

返回: true if successful, otherwise false .

◆ BeginInput()

Int32 BeginInput

(

cnt_tris

)

Call this function before storing triangles into the cache. Removes any previous data and allocates space for cnt_tris number of triangles.

参数

[in]

cnt_tris

The number of triangles to store.

返回: The result: COL

◆ AddTriangle()

Int32 AddTriangle	(	const 向量 &	p1 ,
		const 向量 &	p2 ,
		const 向量 &	p3 ,
		Int32	id
	)

Adds a triangle to the cache with the specified corners and id .

参数

[in]	p1	The first point.
[in]	p2	The second point.
[in]	p3	The third point.
[in]	id	The triangle ID.

返回: The result: COL

◆ EndInput()

Int32 EndInput

(

)

Call this function after storing triangles into the cache.

返回: The result: COL
