Questions
What input is required?
Focal length (positive converging, negative diverging), positive object distance and height, one length unit, title and source note.
What is actually validated?
Normalize length units, apply the thin-lens equation and signed magnification, distinguish real, virtual and infinite images, and draw ray paths and virtual extensions from the calculated geometry.
Can I edit the result?
Yes. The SVG contains text and named vector groups. You can also edit the JSON and rebuild all outputs with the bundled Python script.
Does this require paid generation?
No. The local vector version is complete without a key. Optional PopNow imagery requires a live quote and explicit API USD budget approval.
