### Testing with Bazel

Source: https://github.com/oqton/blenderless/blob/master/README.md

Execute all tests for the Blenderless project using Bazel.

```sh
bazel test //...
```

### Command-Line Interface: Render Geometry to GIF

Source: https://github.com/oqton/blenderless/blob/master/README.md

Use the command-line interface to render a geometry file (STL) to a GIF animation, creating a camera loop around an object.

```sh
bazel run //blenderless -- gif /path/to/foo.stl /path/to/output.gif
```

--------------------------------

### Command-Line Interface: Render YAML Config to Image

Source: https://github.com/oqton/blenderless/blob/master/README.md

Use the command-line interface to render a scene defined in a YAML configuration file to an image.

```sh
bazel run //blenderless -- config /path/to/scene.yml /path/to/output.png
```

--------------------------------

### Command-Line Interface: Render Geometry to Image

Source: https://github.com/oqton/blenderless/blob/master/README.md

Use the command-line interface to render a geometry file (STL) to an image file (PNG). Optionally export the generated .blend file.

```sh
bazel run //blenderless -- image /path/to/foo.stl /path/to/output.png
```

```sh
bazel run //blenderless -- --export-blend-path /path/to/export.blend image /path/to/foo.stl /path/to/output.png # If .blend needs to be exported
```

--------------------------------

### Python Module Usage

Source: https://github.com/oqton/blenderless/blob/master/README.md

Demonstrates how to use the Blenderless Python module for rendering single STL files, from configuration files, and for generating GIF animations. Set 'export_blend_path' to export the generated Blender workspace.

```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)
```

### YAML Configuration for Advanced Scenes

Source: https://github.com/oqton/blenderless/blob/master/README.md

Defines an advanced scene using YAML, specifying camera coordinates, mesh paths, and materials. Supports referencing presets and custom labels.

```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'
```
