# Blenderless Blenderless is the Python package for easy headless rendering using Blender. While Blender is a fantastic open-source 3D modeling software which can be run from the command line, there are still some inconveniences when rendering from a headless server: - the blender python interface `bpy` can only be imported a single time, - and, there is no framebuffer for blender to write to. Furthermore, the `bpy` interface has a steep learning curve. This package is meant to overcome these issues in a easy-to-use manner. It does so by first defining the entire scene and only interacting with the `bpy` at render time in a separate thread using a virtual framebuffer. Example use cases: - Generating thumbnails or previews from 3D files. - Batch generation of views from 3D files. - Automatic generation of compositions of a set of meshes into a single scene - Converting meshes and labels into .blend files - Export GIF animations of a camera looping around an object. ## How to use this ### Resources: - You can find basic examples in the [unit tests](https://github.com/oqton/blenderless/tree/master/tests/test_data). - [Notebook examples](https://github.com/oqton/blenderless/tree/master/notebooks) (point clouds, mesh face colors, ...) ### Python module The blenderless package can be loaded as a module. The main functionality is exposed using the Blenderless class. There is support for Jupyter Notebooks as the images/gifs will be shown as IPython Image objects automatically. ```python from blenderless import Blenderless # Set the following property if you want to export the generated blender workspace. Blenderless.export_blend_path = 'export.blend' # Render single STL file path_to_foo_png = Blenderless.render('meshpath.stl', dest_path=None, azimuth=45, elevation=30, theta=0) # Render from config, note that objects and cameras are defined within the YAML config. path_to_foo_png = Blenderless.render_from_config('config.yml', dest_path=None) # Render GIF animation, note that azimuth is defined by number of frames. path_to_foo_gif = Blenderless.gif(cls, mesh_path, dest_path=None, elevation=30, theta=0, frames=60, duration=2) ``` ### Command-line interface Render geometry file to image ```sh $ blenderless image foo.stl output.png $ blenderless --export-blend-path export.blend image foo.stl output.png # If .blend needs to be exported ``` Render geometry to gif with a camera looping around an object. ```sh $ blenderless gif foo.stl output.gif ``` The following command rendera a YAML config to an image ```sh $ blenderless config scene.yml output.png ``` ### YAML configuration files More advanced scenes can be defined using a YAML configuration file. In this file objects, cameras, labels, materials and presets can be defined. Example: ```yaml scene: # See options in blenderless.scene.Scene preset_path: ../../preset.blend cameras: # See options in blenderless.camera - _target_: blenderless.camera.SphericalCoordinateCamera # Instantiate one camera with following arguments azimuth: 45 elevation: 30 theta: 0 distance: 1 objects: # See blenderless.geometry and blenderless.material - _target_: blenderless.geometry.Mesh # Refers to classes within the blenderless package mesh_path: ../../mesh/3DBenchy.stl # Constructor argument material: # Constructor argument pointing towards another class within the blenderless package _target_: blenderless.material.MaterialFromName material_name: test_material # Link to material name known in present.blend - _target_: blenderless.geometry.BlenderLabel label_value: '42' ``` ### Export blender file ## Install ```buildoutcfg sudo apt-get install xvfb pipx install poetry==1.1.5 make .venv ``` ### Testing ```sh make test ```
