Description

Represents a sequence of vertices.

VertexSeq represents a sequence of vertices with arbitrary attributes, which may be indexed. It uses an OpenGL vertex buffer and an optional index buffer.

The typical creation cycle is:

Creating a new instance of VertexSeq (which is useless on it's own)
Call create to create the underlying data structures
Call prime to obtain a HotVertexSeq (the VertexSeq needs to be created first)

See Also: HotVertexSeq; HotVertexSeq<>

Inherits GLObject.

Member Function Documentation

void create	(	uint16_t	vertexSize,
		uint32_t	vertexCount,
		uint32_t	indexCount = `0`
	)

Creates internal data structures.

Creates a OpenGL vertex buffer (VBO), a vertex array object (VAO), and an optional index buffer when indexCount is not 0.

Note: You cannot call this while another VertexSeq is primed!

Parameters

vertexSize	The size of one vertex in number of GLfloats. If your vertex contains just a position of three floats (x,y,z) the size is 3.
vertexCount	The number of vertices this sequence should hold. If you want to represent a triangle, you need 3 vertices.
indexCount	The number of indicies in the index buffer (0 if you don't need an index buffer)

void prime ( L lambda )

Primes the VertexSeq to obtain a HotVertexSeq.

Binds all OpenGL resources in order to use (writing data) the VertexSeq.

Note: You cannot call prime while another VertexSeq is primed!

Parameters

lambda A functor that accepts a HotVertexSeq& as parameter. It will be called after the HotVertexSeq is created.

Template Parameters

Cs	A list of types of which a vertex consists. If your vertices contain a 3D-Position and a 2D-UV-Coordinate, use those templates: Vec3f, Vec2f

void prime ( std::function< void(HotVertexSeq<> &)> func )

Primes the VertexSeq to obtain a HotVertexSeq.

Binds all OpenGL resources in order to use (writing data) the VertexSeq. This is the type-unsafe overload of prime. Whenever you can, you should use the type-safe variant.

Note: You cannot call prime while another VertexSeq is primed!

Parameters

func	A functor that accepts a HotVertexSeq<>& as parameter. It will be called after the HotVertexSeq is created.
