Charge Facing Dexter Convention Checker
Describe witnessed horizontal facing in viewer x-right coordinates; bearer dexter is viewer left, not a legal pose judgement.
Description
A horizontal facing vector can be translated into viewer and bearer sides.
A horizontal facing vector can be translated into viewer and bearer sides.1
The sign convention matters because bearer dexter appears on the viewer's left.
When to use Charge Facing Dexter Convention Checker
Use this tool to calculate or review the supplied observations under the stated rules. Establish the source tradition, viewing frame, coordinate units and independently annotated features.
How to use Charge Facing Dexter Convention Checker and understand its results
- Establish the source tradition, viewing frame, coordinate units and independently annotated features.
- Enter observedFacingVectorX, using the field meanings and rules below, then run the tool.
- Read result.viewerFacing, result.bearerFacing, using the output meanings and calculation rules below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedFacingVectorX | Observed facing vector x | number | Required |
Supply a finite nonzero horizontal facing-vector component. Negative maps to viewer-left and bearer-dexter; positive maps to viewer-right and bearer-sinister. Zero is rejected because it does not select a horizontal side.
x<0→viewer-left,bearer-dexter; x>0→viewer-right,bearer-sinister Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or reference | object |
| result.viewerFacing | viewer Facing | string |
| result.bearerFacing | bearer Facing | string |

"input": {
"observedFacingVectorX": -1
},
"output": {
"result": {
"viewerFacing": "left",
"bearerFacing": "dexter"
}
}
}Limitations and assumptions
The vector must already be annotated in the stated viewing frame. The tool does not recognize a creature, determine its full pose or assess a source-specific facing rule.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Marshalling Impalement Left-Right Assigner: Heraldic dexter is the bearer's right, which appears on the viewer's left. For a complementary comparison, use Beast Head Facing Direction Decoder: Beast-facing terminology depends on pose, viewing frame and adopted source.
