MeshData

Add this in your code:

#include <engine/graphics/3d_graphics/mesh_data.h>

Description

Asset that stores all the data of a mesh.

Static methods

CreateMeshData

Dynamically create a mesh.

std::shared_ptr<MeshData> CreateMeshData()

Code sample:

std::shared_ptr<MeshData> newMesh = MeshData::CreateMeshData();

Public methods

GetMinBoundingBox

Get the minimum position of the bounding box. (Box including all submeshes).

const Vector3& GetMinBoundingBox() const

Code sample:

std::shared_ptr<MeshData> meshData; // Filled variable
const Vector3& minPos = meshData->GetMinBoundingBox();

GetMaxBoundingBox

Get the maximum position of the bounding box. (Box including all submeshes).

const Vector3& GetMaxBoundingBox() const

Code sample:

std::shared_ptr<MeshData> meshData; // Filled variable
const Vector3& maxPos = meshData->GetMaxBoundingBox();

GetBoundingSphere

Get mesh bounding sphere. (Sphere including all submeshes).

const Sphere& GetBoundingSphere() const

Code sample:

std::shared_ptr<MeshData> meshData; // Filled variable
const Sphere& meshSphere = meshData->GetBoundingSphere();

CreateSubMesh

Create a sub mesh and allocate memory for it.

Parameters:

• vertexCount: The number of vertices allocated
• indexCount: The number of indices allocated
• vertexDescriptorList: The vertex data structure

void CreateSubMesh(uint32_t verticeCount, uint32_t index_count, const VertexDescriptor& vertexDescriptorList)

Code sample:

std::shared_ptr<MeshData> newMesh = MeshData::CreateMeshData();

VertexDescriptor descriptor;
descriptor.AddVertexElement(VertexElements::UV_32_BITS);
descriptor.AddVertexElement(VertexElements::POSITION_32_BITS);

newMesh->CreateSubMesh(6,0, descriptor);

GetSubMesh

Get a submesh by index.

Parameters:

• index: Index of the submesh

const std::unique_ptr<SubMesh>& GetSubMesh(size_t index)

Code sample:

std::shared_ptr<MeshData> meshData; // Filled variable
const std::unique_ptr<SubMesh>& subMesh0 = meshData->GetSubMesh(0);
const std::unique_ptr<SubMesh>& subMesh2 = meshData->GetSubMesh(2);

Update

Update the mesh after a modification on the submeshes.

void Update()
