esp::assets::GltfMeshData class
#include <esp/assets/GltfMeshData.h>

Mesh data storage and loading for gltf format assets. See ResourceManager::loadGeneralMeshData.

Base classes

class BaseMesh: Base class for storing mesh asset data including geometry and topology.

struct RenderingBuffer: Stores render data for the mesh necessary for gltf format.

GltfMeshData(bool needsNormals = true): Constructor. Sets SupportedMeshType::GLTF_MESH to identify the asset type.
~GltfMeshData() virtual: Destructor.

void uploadBuffersToGPU(bool forceReload = false) override: Compile the renderingBuffer_ if first upload or forceReload is true.
void setMeshData(Magnum::Trade::AbstractImporter& importer, int meshID): Load mesh data from a pre-parsed importer for a specific mesh component. Sets the collisionMeshData_ references.
auto getRenderingBuffer() -> RenderingBuffer* virtual: Returns a pointer to the compiled render data storage structure.
auto getMagnumGLMesh() -> Magnum::GL::Mesh* override: Returns a pointer to the compiled render mesh data stored in the renderingBuffer_.

std::unique_ptr<RenderingBuffer> renderingBuffer_: Storage structure for compiled render data. We will use a smart pointer here since each item within the structure (e.g., Magnum::GL::Mesh) does NOT have copy constructor. See uploadBuffersToGPU.
bool needsNormals_

Compile the renderingBuffer_ if first upload or forceReload is true.

Parameters
forceReload	If true, recompiles the renderingBuffer_ (e.g. in the case of data change after initial compilation).

Load mesh data from a pre-parsed importer for a specific mesh component. Sets the collisionMeshData_ references.

Parameters
importer	The importer pre-loaded with asset data from file.
meshID	The local identifier of a specific mesh component of the asset.

Returns a pointer to the compiled render data storage structure.

Returns	Pointer to the renderingBuffer_.

Returns a pointer to the compiled render mesh data stored in the renderingBuffer_.

Returns	Pointer to the compiled render mesh data.
