# face_geometry Protos|Details :--- | :--- [`face_geometry.Environment`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/protos/environment.proto)| Describes an environment; includes the camera frame origin point location as well as virtual camera parameters. [`face_geometry.GeometryPipelineMetadata`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/protos/geometry_pipeline_metadata.proto)| Describes metadata needed to estimate face geometry based on the face landmark module result. [`face_geometry.FaceGeometry`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/protos/face_geometry.proto)| Describes geometry data for a single face; includes a face mesh surface and a face pose in a given environment. [`face_geometry.Mesh3d`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/protos/mesh_3d.proto)| Describes a 3D mesh surface. Calculators|Details :--- | :--- [`FaceGeometryEnvGeneratorCalculator`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/env_generator_calculator.cc)| Generates an environment that describes a virtual scene. [`FaceGeometryPipelineCalculator`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/geometry_pipeline_calculator.cc)| Extracts face geometry for multiple faces from a vector of landmark lists. [`FaceGeometryEffectRendererCalculator`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/effect_renderer_calculator.cc)| Renders a face effect. Subgraphs|Details :--- | :--- [`FaceGeometryFromDetection`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/face_geometry_from_detection.pbtxt)| Extracts geometry from face detection for multiple faces. [`FaceGeometryFromLandmarks`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/face_geometry_from_landmarks.pbtxt)| Extracts geometry from face landmarks for multiple faces. [`FaceGeometry`](https://github.com/google/mediapipe/tree/master/mediapipe/modules/face_geometry/face_geometry.pbtxt)| Extracts geometry from face landmarks for multiple faces. Deprecated, please use `FaceGeometryFromLandmarks` in the new code.
