Detailed Description

Represents a 3D mesh composed of vertices and indices.

The Mesh class encapsulates the vertex data, index data, and the associated OpenGL objects (Vertex Array Object, Vertex Buffer Object, and Index Buffer Object) required to render a 3D model.

Constructor & Destructor Documentation

Mesh() [1/2]

Mesh::Mesh	(	float *	vertices,
		unsigned int	vSize,
		unsigned int *	indices,
		unsigned int	iCount
	)

Constructs a Mesh object from raw C-style arrays.

Parameters

vertices	Pointer to the array of vertex data (e.g., positions, normals, texture coordinates).
vSize	Total size of the vertex data array in bytes.
indices	Pointer to the array of indices that define the triangles.
iCount	Total number of indices.

Mesh() [2/2]

Mesh::Mesh	(	const std::vector< float > &	vertices,
		const std::vector< unsigned int > &	indices
	)

Constructs a Mesh object from C++ std::vector containers.

Parameters

vertices	A constant reference to a vector of floats representing vertex data.
indices	A constant reference to a vector of unsigned integers representing index data.

~Mesh()

Mesh::~Mesh

(

)

Destroys the Mesh object.

This destructor will handle the cleanup of OpenGL resources if the underlying VertexArray, VertexBuffer, and IndexBuffer classes manage their own resource deallocation.

Member Function Documentation

Draw()

void Mesh::Draw

(

)

const

Renders the mesh.

This method binds the associated Vertex Array Object and issues a draw call using the Index Buffer Object.

GetBounds()

void Mesh::GetBounds	(	Vec3 &	minBounds,
		Vec3 &	maxBounds
	)		const

Gets the axis-aligned bounding box of the mesh.

Parameters

minBounds	Output minimum bounds of the mesh.
maxBounds	Output maximum bounds of the mesh.

GetCenter()

Vec3 Mesh::GetCenter

(

)

const

Gets the center point of the mesh bounds.

Returns

The center point of the mesh.

GetIndices()

const std::vector< unsigned int > & Mesh::GetIndices ( ) const

inline

Gets access to the index data for intersection testing.

Returns

Const reference to the index data vector.

GetVertices()

const std::vector< float > & Mesh::GetVertices ( ) const

inline

Gets access to the vertex data for intersection testing.

Returns

Const reference to the vertex data vector.
