Mesh Class Reference

Mesh represents a drawable collection of vertices, textures, and shader data. It stores vertex data, manages a vertex array object (VAO), and allows attaching multiple textures. The mesh also supports serialization of vertex data into a flat array for GPU uploading. More...

	Mesh ()
	Default constructor. Initializes an empty mesh.
	Mesh (const std::vector< Vertex > &pVertices)
	Constructs a mesh using a list of vertices. Automatically creates a vertex array object using the provided vertex data.

	Unloads the mesh by deleting the vertex array object. This frees GPU resources associated with the mesh.
void	AddTexture (Texture *pTexture)
	Adds a texture to the mesh. The texture can later be bound during rendering.

void	SetVertexArray (VertexArray *pVao)
	the vertex array object (VAO) for the mesh. This replaces the current VAO if one exists.

Detailed Description

Mesh represents a drawable collection of vertices, textures, and shader data. It stores vertex data, manages a vertex array object (VAO), and allows attaching multiple textures. The mesh also supports serialization of vertex data into a flat array for GPU uploading.

Constructor & Destructor Documentation

Mesh() [1/2]

Mesh::Mesh

(

)

Default constructor. Initializes an empty mesh.

Mesh() [2/2]

Mesh::Mesh

(

const std::vector< Vertex > &

pVertices

)

Constructs a mesh using a list of vertices. Automatically creates a vertex array object using the provided vertex data.

Parameters

pVertices

The list of vertices that make up the mesh geometry.

Member Function Documentation

AddTexture()

void Mesh::AddTexture

(

Texture *

pTexture

)

Adds a texture to the mesh. The texture can later be bound during rendering.

Parameters

pTexture

Pointer to the texture to add to the mesh.

GetShaderProgram()

ShaderProgram Mesh::GetShaderProgram

(

)

the shader program currently assigned to the mesh.

Returns

The shader program used by this mesh.

GetTexture()

Texture * Mesh::GetTexture

(

int

index

)

Retrieves a texture attached to the mesh at a specified index.

Parameters

index

The index of the texture in the internal texture list.

Returns

Pointer to the texture if it exists, otherwise nullptr.

GetVertexArray()

VertexArray * Mesh::GetVertexArray

(

)

the vertex array object used to render the mesh.

Returns

Pointer to the VertexArray object associated with the mesh.

SetShaderProgram()

void Mesh::SetShaderProgram

(

ShaderProgram

pShaderProgram

)

the shader program to be used by the mesh for rendering.

Parameters

pShaderProgram

The shader program to assign.

SetVertexArray()

void Mesh::SetVertexArray

(

VertexArray *

pVao

)

the vertex array object (VAO) for the mesh. This replaces the current VAO if one exists.

Parameters

pVao	Pointer to the VertexArray object.

ToVerticeArray()

float * Mesh::ToVerticeArray

(

)

Converts the mesh's vertex data into a flat float array suitable for GPU uploading. Each vertex contributes 8 floats (position [3], normal [3], uv [2]).

Returns

Pointer to a newly allocated float array. Caller is responsible for deleting it.

Unload()

void Mesh::Unload

(

)

Unloads the mesh by deleting the vertex array object. This frees GPU resources associated with the mesh.
