Detailed Description

Immutable GPU mesh (VAO + VBO + optional EBO).

Non-copyable — each instance owns unique GL handles. Vertex data is uploaded to the GPU in the constructor and released from CPU memory immediately; the GL objects live until the Mesh is destroyed.

Constructor & Destructor Documentation

Mesh() [1/3]

mnd::Mesh::Mesh	(	const VertexLayout &	layout,
		const std::vector< float > &	vertices,
		const std::vector< uint32_t > &	indices
	)

Upload indexed geometry to the GPU.

Parameters

layout	Describes how vertex bytes map to shader attributes.
vertices	Interleaved vertex data (position, normal, UV …).
indices	Triangle list indices into the vertex array.

Definition at line 50 of file Mesh.cpp.

References mnd::VertexLayout::elements, mnd::Engine::GetGraphicsAPI(), mnd::Engine::GetInstance(), LOG_INFO, and mnd::VertexLayout::stride.

Mesh() [2/3]

mnd::Mesh::Mesh	(	const VertexLayout &	layout,
		const std::vector< float > &	vertices
	)

Upload non-indexed geometry to the GPU.

Parameters

layout	Vertex attribute layout.
vertices	Interleaved vertex data; drawn with glDrawArrays.

Draw()

void mnd::Mesh::Draw
