Member Function Documentation

accept()

void accept ( Visitor &  )

overridevirtual

Accept a visit from our friendly visitor.

Reimplemented from Drawable.

render()

void render ( const Camera &  camera )

overridevirtual

Parameters

camera

The current camera to be used for rendering.

Reimplemented from Drawable.

addVertices() [1/3]

unsigned int addVertices	(	const Core::Array< Vector3f > &	vertices,
		const Core::Array< Vector3f > &	normals,
		const Core::Array< Vector4ub > &	colors
	)

Add vertices to the object. Note that this just adds vertices to the object. Use addTriangles with size_t indices to actually draw them.

Parameters

vertices	The 3D vertex points to add to the drawable.
normals	The normal direction at the vertex.
colors	Vertex color. If not specified, use the current color() and opacity(). If the 3 component color is set, the current opacity() is used.

Note

All arrays must be the same length, or this function call will fail, returning InvalidIndex.

Returns

The index of the first vertex added by this call, used to specify element arrays for the actual triangles.

addVertices() [2/3]

unsigned int addVertices	(	const Core::Array< Vector3f > &	vertices,
		const Core::Array< Vector3f > &	normals,
		const Core::Array< Vector3ub > &	colors
	)

Add vertices to the object. Note that this just adds vertices to the object. Use addTriangles with size_t indices to actually draw them.

Parameters

vertices	The 3D vertex points to add to the drawable.
normals	The normal direction at the vertex.
colors	Vertex color. If not specified, use the current color() and opacity(). If the 3 component color is set, the current opacity() is used.

Note

All arrays must be the same length, or this function call will fail, returning InvalidIndex.

Returns

The index of the first vertex added by this call, used to specify element arrays for the actual triangles.

addVertices() [3/3]

unsigned int addVertices	(	const Core::Array< Vector3f > &	vertices,
		const Core::Array< Vector3f > &	normals
	)

Add vertices to the object. Note that this just adds vertices to the object. Use addTriangles with size_t indices to actually draw them.

Parameters

vertices	The 3D vertex points to add to the drawable.
normals	The normal direction at the vertex.
colors	Vertex color. If not specified, use the current color() and opacity(). If the 3 component color is set, the current opacity() is used.

Note

All arrays must be the same length, or this function call will fail, returning InvalidIndex.

Returns

The index of the first vertex added by this call, used to specify element arrays for the actual triangles.

addTriangle()

void addTriangle	(	unsigned int	index1,
		unsigned int	index2,
		unsigned int	index3
	)

Add triangles to the mesh. Triangles are specified as 3-tuples of vertex indices. Must call addVertices first, and use the return value to obtain the valid index range.

addTriangles()

void addTriangles

(

const Core::Array< unsigned int > &

indices

)

Add triangles to the mesh. Triangles are specified as 3-tuples of vertex indices. Must call addVertices first, and use the return value to obtain the valid index range.

clear()

void clear ( )

overridevirtual

Clear the contents of the node.

Reimplemented from Drawable.

vertexCount()

size_t vertexCount

(

)

const

Get the number of vertices.

indexCount()

size_t indexCount

(

)

const

Get the number of vertices.

triangleCount()

size_t triangleCount

(

)

const

Get the number of triangles.

setColor()

void setColor

(

const Vector3ub &

c

)

The default color of the mesh. This is used to set the color of new vertices when no explicit vertex color is specified.

color()

Vector3ub color

(

)

const

The default color of the mesh. This is used to set the color of new vertices when no explicit vertex color is specified.

setOpacity()

void setOpacity

(

unsigned char

opacity_

)

The default opacity of the mesh. This is used when either no explicit vertex color is specified, or a three component color is used.

opacity()

unsigned char opacity

(

)

const

The default opacity of the mesh. This is used when either no explicit vertex color is specified, or a three component color is used.
