Detailed Description

Format-independent abstract Mesh base class. Each mesh consists of a VertexBuffer, an IndexBuffer and a vertex array. This class realizes the RAII-idiom w.r.t. the vertex array.

The class maintains a so-called OpenGL vertex array in RAII-manner, which, contrary to its name, basically is a conjunction of vertex and index buffer. Because a vertex array is not sharable across OpenGL contexts, objects from this class are always coupled to a particular context.

Any OpenGL object types which are not containers are sharable, as well as Sync Objects and GLSL Objects (excluding program pipeline objects). All container objects are not shared between contexts. [1]

Container objects:

Framebuffer Objects

Program Pipeline

Transform Feedback Objects

Vertex Array Objects [2]

Constructor & Destructor Documentation

◆ MeshBase()

Carna::base::MeshBase::MeshBase	(	const VertexAttributes &	va,
		Association< VertexBufferBase > *	vertexBuffer,
		Association< IndexBufferBase > *	indexBuffer
	)

Creates new mesh. It is only valid within the current OpenGL context.

Postcondition: &GLContext::current() == &glContext

◆ ~MeshBase()

virtual Carna::base::MeshBase::~MeshBase ( )

virtual

Deletes.

Precondition: &GLContext::current() == &glContext

Member Function Documentation

◆ bind()

void Carna::base::MeshBase::bind ( ) const

Binds the vertex array object.

Precondition: &GLContext::current() == &glContext

◆ render()

void Carna::base::MeshBase::render ( ) const

Renders the mesh.

Precondition: &GLContext::current() == &glContext
