Detailed Description

template<typename ExtensionManager = gltf::ExtensionManager<gltf::Extension>>
class oe::scene::loader::GltfWithExtensions< ExtensionManager >

Load a glTF asset with custom extensions registered.

To use, you should first inherit from gltf::Extension to provide your implementation then generate an gltf::ExtensionManager that bind your extensions to their names

For example:

class ExampleExtension : public oe::scene::gltf::Extension
{
    // ...
};
 
using MyExtensionsManager = oe::scene::gltf::ExtensionManager<ExampleExtension>;
using MyGltfLoader = oe::scene::loader::GltfWithExtensions<MyExtensionsManager>;
 
// Then before loading the asset
MyExtensionsManager my_gltf_extensions;
my_gltf_extensions.addExtension<ExampleExtension>("EXAMPLE_extension_name");
 
MyGltfLoader gltf_loader(my_gltf_extensions);
 
// Then you can use the loader as the original Gltf loader
gltf_loader.load(filename, is_binary);
