Overlap — identifying and avoiding tangents
Arrange overlapping forms so depth reads clearly and edge tangents do not create confusing joins.
What it is
Overlap places one shape visibly in front of another. A contour crossing another shape shows which form is closer.
Tangents are near-touches, parallel edges, or accidental alignments. Examples include a hand touching a head silhouette, a horizon aligned with a neck, or a spear tip grazing the frame. These joins can flatten space and interrupt the read.
You check contours at the sketch, line, and final render stages. You can separate forms with a gap or adjust them to create a definite overlap. Deliberate overlaps can show depth and staging, such as a hand in front of a face or foliage crossing a character.
Why it matters
Overlap supports depth, staging, and story. Weak overlap control can make characters feel separate from the setting, merge forms, or draw attention to awkward edge joins.
You can check it when
- ✓Scan line art or flats and identify tangents, including kissing edges, touching corners, and alignments that obscure depth.
- ✓Check silhouettes with shading and texture removed. You can tell which objects are in front.
- ✓Adjust a limb, prop, or horizon to turn a near-touch into a definite overlap or a gap.
- ✓Review finished pieces for unintentional merges, such as a weapon aligning with a head or a limb joining a background shape.
