Constructor & Destructor Documentation

Mesh ( const std::vector< Vertex > &  vertices,
const std::vector< uint32 > &  indices,
const std::vector< MeshSurface > &  surfaces,
const std::string &  name 
)

Creates a Mesh from vertices

Parameters
verticesVertices
indicesIndexes of vertices
surfacesSurfaces
name
Mesh ( const std::string &  name)
inline
~Mesh ( )
override

Member Function Documentation

void buildAABB ( )
const AABB& getAABB ( ) const
inline

Returns the local space axis aligned bounding box

std::vector<uint32>& getIndices ( )
inline

Return all the vertices indexes

const std::vector<uint32>& getIndices ( ) const
inline

Return all the vertices indexes

auto getIndicesIndex ( ) const
inline
auto& getMaterials ( )
inline
const auto& getMaterials ( ) const
inline
constexpr const std::string& getName ( ) const
inlineconstexpr
unique_id getSurfaceMaterial ( const uint32  surfaceIndex) const
inline

Returns the material for a given surface

Parameters
surfaceIndexZero-based index of the surface
std::vector<MeshSurface>& getSurfaces ( )
inline

Returns all the Surfaces

const std::vector<MeshSurface>& getSurfaces ( ) const
inline

Returns all the Surfaces

auto getSurfacesIndex ( ) const
inline
std::vector<Vertex>& getVertices ( )
inline

Returns all the vertices

const std::vector<Vertex>& getVertices ( ) const
inline

Returns all the vertices

auto getVerticesIndex ( ) const
inline
auto isUploaded ( ) const
inline
bool operator== ( const Mesh &  other) const
void setSurfaceMaterial ( uint32  surfaceIndex,
unique_id  material 
)

Changes the material of a given surface. Warning: this will update the data in memory only but not the node in the scene. If the material needs a different pipeline, the change will not appear. Use MeshInstance::setSurfaceMaterialOverride instead.

Parameters
surfaceIndexZero-based index of the Surface
materialNew material for the Surface
