Visualizer

[Doralitze]

The following issues still need to be resolved:

• Fix issue that W channel is not used in RGBW mode
• Fix issue that color mapping is not applied automatically on add fixture with selected reference from show file
• Fix issue that Loading of .stage YAML files does not always work, requiring deletion and addition of all fixtures
• Fix issue that directly looking into a beam does not render any light. A lense flare is not required, just a flat texture providing the current color
• Fix behavior of dimmer channel
• Load max movement angles from fixture definitions.
• Implement color wheel support (@Doralitze will take care of this once refactoring is done)
• Implement non-colored light support. Use the physical properties from the OFL model to get a light temperature of the bulb. (@Doralitze will take care of this once refactoring is done)
• Implement par cans. (@Doralitze will take care of this once refactoring is done)
• Refactor source code to implement separation of concerns (for example one should have different classes for different fixture renderers
• Add setting (General) to show file to load specified stage file automatically. @Doralitze will take care of this.
• Remove default stage file from source tree.

Remaining issues will be addressed in future work.

• Regarding refactoring: model/stage.py should be a package with classes from that file being in their own files.
• resource/data/stage.yaml should be removed.
• stage_editor_widget must be splitted into multiple files as well. In addition, the GL control logic and side bar widgets should be separated.
• The shaders in stage_gl_widget.py should be separate files in the source tree.
• The model loading should be moved from stage_gl_widget.py to a separate class and file.
• The methods _traverse_gltf and _upload_vao also belongs to the 3D model class.
• A visualizer fixture needs to have its own class with capability mixins (for example can_move or emits_light) to ensure one can add fixtures with different traits (For example an LED bar which cannot move but has many pixels in its matrix) later on.

After each change, functionality must be tested in order to avoid regression.
After all of this is addressed, a second round of refactoring might be in order.
