bool LoadBuffers(bool firstBufferIsGLB)
Reads the model's buffer metadata, then uses it to load all buffers into the model.
bool LoadModelMetaDataFromFile(std::string &FileName, std::vector< std::string > &usedExtensions)
Reset internal Model struct, and serialize glTF metadata (all json information) into it.
static const unsigned short GL_TRIANGLE_STRIP
Deserialize a GLTF model file.
