Member Function Documentation

bindVertexAttributes()

template<typename V >

void oe::render::CommonMesh::bindVertexAttributes

(

)

Bind vertex attributes for the vertex type V

Parameters

id_vertex_buffer

Vertex buffer to update

Note

please specialize this function with your own vertex type if you add a new one

bindVertexAttributeToPointer()

template<typename VertexType , typename T >

void oe::render::CommonMesh::bindVertexAttributeToPointer ( const uint32_t  index, const size_t  offset  )

inlinenoexcept

Enable and bind a vertex attribute of type T to the location, and fill value from offset in structure VertexType

Parameters

index	index of the vertex attribute to be modified
offset	Offset to get the component

renderArrays()

void oe::render::CommonMesh::renderArrays	(	const uint32_t	count,
		const uint32_t	offset = 0,
		const uint32_t	mode = 0x0004
	)

Ask the GPU to render only the vertices

Parameters

offset	id of first vertex to draw
count	total vertices to draw
mode	MeshDrawMode to specify how to render the mesh (default are triangles)

setSubBufferData()

void oe::render::CommonMesh::setSubBufferData	(	const uint32_t	size,
		const void *	data,
		const uint32_t	offset = 0
	)

Partial update of buffer
