Methods

`Static`initializeFromDimensions

initializeFromDimensions(sceneDims: SceneDimensions): ViewState
Initialize ViewState from scene dimensions
Parameters
- sceneDims: SceneDimensions
Returns ViewState
- Defined in src/data/view-state-manager.ts:41

`Static`validateDimensions

validateDimensions(dimensions: DimensionMetadata[]): ValidationResult
Validate scene dimensions for consistency and correctness
Parameters
- dimensions: DimensionMetadata[]
Returns ValidationResult
- Defined in src/data/view-state-manager.ts:65

`Private` `Static`extractMetadata

extractMetadata(sceneDims: SceneDimensions): DimensionMetadata[]
Extract and normalize metadata from scene dimensions
Parameters
- sceneDims: SceneDimensions
Returns DimensionMetadata[]
- Defined in src/data/view-state-manager.ts:92

`Private` `Static`findDisplayedDimensions

findDisplayedDimensions(metadata: DimensionMetadata[]): number[]
Find which dimensions should be displayed (max 3)
Parameters
- metadata: DimensionMetadata[]
Returns number[]
- Defined in src/data/view-state-manager.ts:117

`Private` `Static`calculateInitialSlice

calculateInitialSlice(
metadata: DimensionMetadata[],
displayed: number[],
): number[]
Calculate initial slice position for all dimensions.

Policy (aligned with SceneDimsManager.initFromScene):
- Discrete/categorical non-displayed: start at minimum (first frame/category)
- Continuous non-displayed: start at center (no natural "first" position)
- Displayed: start at 0 (camera-controlled)
Parameters
- metadata: DimensionMetadata[]
- displayed: number[]
Returns number[]
- Defined in src/data/view-state-manager.ts:137

`Private` `Static`buildToleranceArray

buildToleranceArray(
metadata: DimensionMetadata[],
displayed: number[],
): number[]
Build tolerance array based on dimension types
Parameters
- metadata: DimensionMetadata[]
- displayed: number[]
Returns number[]
- Defined in src/data/view-state-manager.ts:165

`Private` `Static`checkDuplicateNames

checkDuplicateNames(dimensions: DimensionMetadata[], warnings: string[]): void
Check for duplicate dimension names
Parameters
- dimensions: DimensionMetadata[]
- warnings: string[]
Returns void
- Defined in src/data/view-state-manager.ts:209

`Private` `Static`checkDisplayCount

checkDisplayCount(dimensions: DimensionMetadata[], warnings: string[]): void
Check displayed dimension count
Parameters
- dimensions: DimensionMetadata[]
- warnings: string[]
Returns void
- Defined in src/data/view-state-manager.ts:224

`Private` `Static`validateDimension

validateDimension(
    dim: DimensionMetadata,
    index: number,
    _errors: string[],
    warnings: string[],
): void
Validate a single dimension
Parameters
- dim: DimensionMetadata
- index: number
- _errors: string[]
- warnings: string[]
Returns void
- Defined in src/data/view-state-manager.ts:242

`Static`logValidationResults

logValidationResults(
    validation: ValidationResult,
    ndim: number,
    displayedCount: number,
): void
Log validation results
Parameters
