Detailed Description

Container for Triangle objects.

There are also static methods to deal with Triangle object and its components to leave Triangle structure as POD.

static float TriangleSet::distance	(	Vertex	a,
		Vertex	b
	)			[inline, static]

Compute distance of two vertexes.

Parameters:

	a	Vertex a.
	b	Vertex b.

Returns:

Return distance of vertexes a and b.

Definition at line 33 of file TriangleSet.h.

References Vertex::x, Vertex::y, and Vertex::z.

static Vertex TriangleSet::centre	(	Vertex	a,
		Vertex	b
	)			[inline, static]

Compute center of two vertexes.

Note:

Used for patch division.

Parameters:

	a	Vertex a.
	b	Vertex b.

Returns:

Return center of vertexes a and b as Vertex.

References Vertex::x, Vertex::y, and Vertex::z.

void TriangleSet::add

(

Triangle *

triangle

)

Add copy of triangle to container.

Note:

There is no need to keep Triangle object in memory outside this class.

Parameters:

triangle

Pointer to triangle to copy to container.

void TriangleSet::add

(

TriangleSet *

tset

)

Add copy of triangles to container.

Note:

There is no need to keep Triangle objects in memory outside this class.

Parameters:

tset

Pointer to TriangleSet containing source triangles.

size_t TriangleSet::count

(

)

Return current count of triangle stored in container.

Returns:

Return current count of triangle stored in container.

Triangle& TriangleSet::operator[]

(

unsigned

index

)

Access triangle using its index.

Parameters:

index

Index of triangle - must be in range <0, count()-1>.

Returns:

Return reference to desired triangle.

float TriangleSet::size< 1 >

(

Triangle *

triangle

)

[inline, static]

Compute triangle size.

Template parameter QUALITY Switch algorithm to express triangle size (0 - girth, 1 - area). There are two way to express triangle size - girth and area. The 1st is faster, the 2nd is realistic.

Parameters:

triangle

Triangle to compute.

Returns:

Return triangle size using selected algorithm.

static TriangleSet* TriangleSet::divide

(

Triangle *

triangle

)

[static]

Divide triangle to 4 triangles, each with 1/4 area.

Note:

Vertex oriantation is kept.

Parameters:

triangle

Pointer to triangle to divide.

Returns:

Return TriangleSet object (allocated on the heap) containing 4 triangles.
