Detailed Description

template<typename PosT, typename TexCoordT = detail::NullAtribT, typename ColorT = detail::NullAtribT>
struct ImFusion::GL::FixedFunctionPipeline::VertexData< PosT, TexCoordT, ColorT >

Utility struct to build a VertexBuffer to be used with FixedFunctionPipeline in a type-safe fashion.

You can either fill a VertexBuffer with the data using assign() or create a new one using createBuffer(). This interface also provides an implicit conversion to std::unique_ptr<VertexBuffer> to minimize code overhead.

Note

Do instantiate this class manually but use the FixedFunctionPipeline::makeVertexData() factory function:

std::vector<vec2> vertices = ...;
std::vector<vec2> texCoords = ...;
std::unique_ptr<VertexBuffer> vbo = FixedFunctionPipeline::makeVertexData(vertices).useTexCoords(texCoords);

Public Member Functions
template<typename T>
VertexData< PosT, TexCoordT, T >	useColors (const std::vector< T > &colors) const
	Add per-vertex colors to the vertex data.
template<typename T>
VertexData< PosT, T, ColorT >	useTexCoords (const std::vector< T > &texCoords) const
	Add per-vertex texture coordinates to the vertex data.
void	assign (VertexBuffer &buffer) const
	Assign the previously specified vertex data to the given buffer.
std::unique_ptr< VertexBuffer >	createBuffer () const
	Create a new GlVertexBuffer and fill it with the previously provided vertex data.
	operator std::unique_ptr< VertexBuffer > () const
	Implicit conversion to a std::unique_ptr<GL::VertexBuffer>.

Public Attributes
const std::vector< PosT > *	m_vertices
	Pointer to vertex position data, must not be 0.
const std::vector< TexCoordT > *	m_texCoords
	Pointer to vertex texture coordinate data, points to detail::emptyBuffer if not specified.
const std::vector< ColorT > *	m_colors
	Pointer to vertex color data, points to detail::emptyBuffer if not specified.

useColors()

template<typename PosT, typename TexCoordT = detail::NullAtribT, typename ColorT = detail::NullAtribT>

template<typename T>

VertexData< PosT, TexCoordT, T > ImFusion::GL::FixedFunctionPipeline::VertexData< PosT, TexCoordT, ColorT >::useColors

(

const std::vector< T > &

colors

)

const

Add per-vertex colors to the vertex data.

The number of colors must match the number of vertex positions.

useTexCoords()

template<typename PosT, typename TexCoordT = detail::NullAtribT, typename ColorT = detail::NullAtribT>

template<typename T>

VertexData< PosT, T, ColorT > ImFusion::GL::FixedFunctionPipeline::VertexData< PosT, TexCoordT, ColorT >::useTexCoords

(

const std::vector< T > &

texCoords

)

const

Add per-vertex texture coordinates to the vertex data.

The number of colors must match the number of vertex positions.

assign()

template<typename PosT, typename TexCoordT = detail::NullAtribT, typename ColorT = detail::NullAtribT>

void ImFusion::GL::FixedFunctionPipeline::VertexData< PosT, TexCoordT, ColorT >::assign

(

VertexBuffer &

buffer

)

const

Assign the previously specified vertex data to the given buffer.

Note

The buffer will remain bound to the current OpenGL state.

createBuffer()

template<typename PosT, typename TexCoordT = detail::NullAtribT, typename ColorT = detail::NullAtribT>

std::unique_ptr< VertexBuffer > ImFusion::GL::FixedFunctionPipeline::VertexData< PosT, TexCoordT, ColorT >::createBuffer

(

)

const

Create a new GlVertexBuffer and fill it with the previously provided vertex data.

Note

The buffer will remain bound to the current OpenGL state.
