Conversation
📝 Walkthrough## Walkthrough
The changes incorporate a new mirroring functionality into dataset rotation settings. A `Checkbox` component is added to allow users to specify if an axis rotation should be mirrored, and the rotation structure is updated to include both the rotation degree and the mirror flag. Function signatures and type names—renaming `DatasetRotation` to `DatasetRotationAndMirroringSettings`—are modified accordingly. Additionally, a layout adjustment is made in the dataset settings view, and the transformation accessor functions are revised to compute rotations using the new `RotationAndMirroringSettings` type.

79-96:⚠️ Potential issueBug in mirroring toggle handling.
When the
isMirroredparameter is false, it won't update the rotation values because of the conditionif (isMirrored). This means toggling mirroring off won't work correctly.Apply this fix:
-if (isMirrored) { - rotationValues.isMirrored = isMirrored; +if (isMirrored !== undefined) { + rotationValues.isMirrored = isMirrored; }

149-161: New checkbox for mirror functionality.The added checkbox component allows users to toggle mirroring for each axis. The label and formatting look good, but the comment is misleading.
-label={`Mirror ${axis.toUpperCase()} Axis`} /* Whitespace label is needed for correct formatting*/ +label={`Mirror ${axis.toUpperCase()} Axis`}Consider also adding a tooltip explaining what mirroring does:

212-213: Default initialization for rotation settings.The code initializes rotation settings with default values for both rotation degrees and mirroring state.
Consider adding a comment explaining the default values, especially for the
isMirroredproperty:-const nulledSetting = { rotationInDegrees: 0, isMirrored: false }; +// Initialize with no rotation and no mirroring by default +const nulledSetting = { rotationInDegrees: 0, isMirrored: false };frontend/javascripts/oxalis/model/accessors/dataset_layer_transformation_accessor.ts (1)
407-409: Updated comments to indicate mirroring possibility.The comments have been updated to indicate that the rotation transformations may include mirroring, which is helpful for understanding the transformation pipeline.
Consider adding a brief explanation of what mirroring means in this context:
-// 2. Rotation around x-axis (potentially mirrored) -// 3. Rotation around y-axis (potentially mirrored) -// 4. Rotation around z-axis (potentially mirrored) +// 2. Rotation around x-axis (potentially mirrored - flipping the axis orientation) +// 3. Rotation around y-axis (potentially mirrored - flipping the axis orientation) +// 4. Rotation around z-axis (potentially mirrored - flipping the axis orientation)

304-305: Appropriate UI adjustment for new mirroring functionality.The column width has been increased from
xl={6}toxl={12}to accommodate the new mirroring controls in theAxisRotationSettingForDatasetcomponent. This layout change ensures that the rotation settings and mirroring checkboxes have sufficient space.frontend/javascripts/dashboard/dataset/dataset_rotation_form_item.tsx (3)
4-4: Added checkbox import for new mirroring functionality.The import of the Checkbox component is required for the newly added mirroring controls.
58-62: Updated rotation values structure to support mirroring.The rotation values structure now uses the
RotationSettingtype which includes both rotation degree and mirroring information.
170-174: Type renamed for better clarity.The type has been renamed from
DatasetRotationtoDatasetRotationSettingsto better represent its purpose, and its structure has been updated to use the newRotationSettingtype for each axis.frontend/javascripts/dashboard/dataset/dataset_settings_view.tsx (3)
31-31: Updated function name to reflect its expanded functionality.The function has been renamed from
getRotationFromTransformationIn90DegreeStepstogetRotationSettingsFromTransformationIn90DegreeStepsto reflect that it now returns both rotation degree and mirroring information.
85-85: Updated FormData type to use new DatasetRotationSettings.The FormData type has been updated to use the renamed and restructured
DatasetRotationSettingstype.
216-229: Updated to use new rotation settings structure.The code now correctly initializes rotation settings for each axis using the new
getRotationSettingsFromTransformationIn90DegreeStepsfunction, which returns both rotation degree and mirroring information.frontend/javascripts/oxalis/model/accessors/dataset_layer_transformation_accessor.ts (4)
74-74: Added helper constant for axis indexing.This new constant maps axis names to their corresponding positions in the transformation matrix, making the code more readable and maintainable.
76-79: New type to support mirroring functionality.The new
RotationSettingtype nicely encapsulates both the rotation angle and mirroring state, providing a clean way to handle these related properties together.
81-105: Updated rotation extraction function to include mirroring detection.The function now detects both rotation angle and whether mirroring is applied, returning this information as a
RotationSettingobject. The implementation correctly identifies mirroring by checking the sign of the diagonal matrix element corresponding to the axis.
123-144: Added mirroring support to rotation matrix generation.The function now handles mirroring by conditionally applying a scale transformation that flips the axis. The implementation correctly combines rotation and mirroring transformations.

4-4: Consider unifying your imports from Ant Design.Importing directly from "antd" rather than "antd/lib/checkbox/Checkbox" can help maintain consistency across your codebase:
- import Checkbox, { type CheckboxChangeEvent } from "antd/lib/checkbox/Checkbox"; + import { Checkbox, type CheckboxChangeEvent } from "antd";

9-9: The added import forRotationSettinglooks good.
14-14: ImportingtransformationEqualsAffineIdentityTransformis appropriate for pruning identity transformations.
59-63: Defining a structuredrotationValuesobject enhances clarity.
80-81: AllowingisMirroredas an optional parameter is a solid extension of the API.
110-116: Setting transformations tonullwhen they are effectively identity is a good space-saver.
125-125: Adjusting theCollayout span to 8 is a fine layout change.
127-127: Using["datasetRotation", axis, "rotationInDegrees"]aligns with your new rotation model.
137-137: Keeping the field name consistent for the InputNumber is correct.
153-153: Changing the layout span for the next column to 4 is consistent with the UI adjustments.
154-166: Adding theisMirroredcheckbox integrates well with the refined rotation logic.Though note that toggling from checked to unchecked depends on the fix suggested in lines 90-96 for properly clearing the flag.
175-178: Renaming and exportingDatasetRotationSettingsimproves type clarity for all axes.frontend/javascripts/oxalis/model/accessors/dataset_layer_transformation_accessor.ts (7)
74-74: IntroducingaxisPositionInMatrixclarifies index lookups for different axes.
76-79: DefiningRotationSettingas a distinct type is a clean approach to storing rotation angles and mirroring.
80-105:getRotationSettingsFromTransformationIn90DegreeStepsneatly extracts angle and mirroring details in 90° increments.
125-137:getRotationMatrixAroundAxiscorrectly applies both rotation and mirroring.
384-392: Mirroring check relies on vector length, which can miss negative scales.Use an absolute value approach per axis to accurately detect mirrored transformations:
- return translation.length() === 0 && scale.length() === NON_SCALED_VECTOR.length(); + return translation.length() === 0 && + Math.abs(scale.x) === 1 && Math.abs(scale.y) === 1 && Math.abs(scale.z) === 1;
407-409: These updated comments help clarify that each axis can be mirrored.
463-483:transformationEqualsAffineIdentityTransformis a thorough check for identity transformations.

81-81: Update function signature to handle degrees=0 case.The function signature has been updated to accept an optional
isMirroredboolean, butrotationInDegreesis typed asnumber | undefinedwhich is different from the previous type of justnumber.- (rotationInDegrees: number | undefined, isMirrored?: boolean): void => { + (rotationInDegrees: number | null | undefined, isMirrored?: boolean): void => {This would be more consistent with how you handle the InputNumber in lines 146-149 where
nullis a possible value.
153-166: Consider adding a tooltip to explain the mirror feature.The mirroring checkbox lacks additional explanation that would help users understand what mirroring does. Consider adding a tooltip similar to what you've done for the rotation slider.
<FormItem name={["datasetRotation", axis, "isMirrored"]} colon={false} valuePropName="checked" - label={`Mirror ${axis.toUpperCase()} Axis`} /* Whitespace label is needed for correct formatting*/ + label={`Mirror ${axis.toUpperCase()} Axis`} > <Checkbox onChange={(evt: CheckboxChangeEvent) => setMatrixRotationsForAllLayer(undefined, evt.target.checked) } + title={`Flip the dataset along the ${axis}-axis.`} /> </FormItem>Or, for consistency with the rotation controls, use the
FormItemWithInfocomponent:- <FormItem + <FormItemWithInfo name={["datasetRotation", axis, "isMirrored"]} colon={false} valuePropName="checked" label={`Mirror ${axis.toUpperCase()} Axis`} + info={`Flip the dataset along the ${axis}-axis.`} >

4-4: Good addition of required imports for the new mirroring functionality.The necessary imports for Checkbox component, RotationSetting type, and the transformationEqualsAffineIdentityTransform function have been correctly added.
Also applies to: 9-9, 14-14
59-63: Well-structured implementation of the RotationSetting type.The rotation values structure has been properly updated to use the RotationSetting type for each axis, which supports the new mirroring functionality.
80-81: Good function signature update for mirroring support.The setMatrixRotationsForAllLayer function signature has been appropriately updated to support setting rotation degrees and mirroring independently.
90-97: Robust implementation for handling rotation and mirroring settings.The implementation correctly handles both rotation degrees and mirroring flags, with proper undefined checks to ensure values are only updated when explicitly set. This properly addresses the previous issues with toggling off mirroring and setting rotation to 0 degrees.
110-113: Excellent optimization for identity transformations.Setting coordinateTransformations to null when they equal the identity transform is a good optimization that prevents storing unnecessary identity transformations.
125-166: Well-designed UI layout for the mirroring functionality.The layout has been effectively reorganized to accommodate the new mirroring checkbox, with appropriate column spans and form item configurations. The connection between the UI and the underlying data model is well implemented.
175-179: Good type renaming for clarity.Renaming DatasetRotation to DatasetRotationSettings and updating its structure to use RotationSetting for each axis improves code clarity and better reflects the expanded functionality.

Learning: The function `isRotationAndMirrorMaybeOnly` in the dataset_layer_transformation_accessor.ts is intentionally designed to allow mirroring transformations (negative scale values). It uses the length comparison (`scale.length() === NON_SCALED_VECTOR.length()`) rather than component equality to permit mirrored axes while ensuring the overall scale magnitude remains the same.

4-4: Import from antd Checkbox library is correct.
No issues identified here.
9-9: Properly importing the new type.
IncludingRotationAndMirroringSettingsaligns with the updated transformations.
14-14: Importing the identity transformation check.
This import cleanly references the helper for skipping identity transforms.
80-81: Extended setter signature for mirroring.
AllowingisMirroredto be optional is consistent with partial updates.
90-98: Partial updates preserve toggling off.
This conditional assignment correctly updates only the provided properties, preventing stale values.
112-115: Verify setting transformations to null for the identity case.
Nulling coordinate transformations if they are effectively no-ops is valid, but confirm it won't break downstream consumers expecting an array.
118-118: Assigning updated transformations.
Straightforward approach to store the new transformations.
127-127: Layout adjustment.
Changing the column span is purely a UI concern and seems fine.
129-129: Linking rotation controls to the form.
Binding rotation values to"datasetRotation"is consistent.
139-139: Consistent name property usage.
Coordinates the same"rotationInDegrees"field for the numeric input.
155-168: Mirroring checkbox added.
This correctly updatesisMirroredupon user toggling. Good integration withsetMatrixRotationsForAllLayer.
177-180: Introducing a combined type for rotation and mirroring.
Renaming toDatasetRotationAndMirroringSettingsis clear and descriptive.frontend/javascripts/oxalis/model/accessors/dataset_layer_transformation_accessor.ts (10)
74-74: Matrix index mapping for axes.
This helper object provides clarity in accessing matrix entries per axis.
76-79: Definition of rotation and mirroring settings.
Straightforward type combining angle and boolean mirror flag.
82-85: Renamed function to reflect multiple properties.
getRotationSettingsFromTransformationIn90DegreeStepsclarifies that mirroring is also inferred.
87-87: Fallback for non-affine transformations.
Returning{ rotationInDegrees: 0, isMirrored: false }is suitable for ignoring non-affine transforms.
90-90: Mirroring detection via the diagonal component.
This negative check on the axis diagonal is a concise solution for a flipped axis sign.
104-104: Protected return structure.
Safely returns a valid angle and the new mirror state.
123-123: Updated function signature for rotation and mirroring.
This ensures the matrix can handle both transformations.
128-137: Combining rotation and scale for mirroring.
Applying a negative scale whenisMirroredis true is a well-established approach.
410-412: Descriptive axis-level documentation.
Renaming to reflect potential mirroring for each axis is clear.
466-485: Identity transformation detection.
The check ensures each transformation is affine and then reduces them to confirm identity. This is consistent and readable.
This is a follow up for #8159. The rotation feature now allows to mirror datasets along axes as well.
Moreover, the rotation settings no longer save a transformation in case it is "nulled" for every setting resulting in an identity transform.
