3D scenes, cameras, and lights

Replace this area with a screenshot or short walkthrough video during the media sweep.

3D Canvas work needs a clear scene scale, camera strategy, light setup, and depth ownership before procedural effects or interaction are added.

Where this fits

Scene scale

  • Choose a unit scale and keep object positions, camera distance, physics values, and procedural fields in that same mental model.
  • Use named anchors or empty objects when several animated objects need to share a coordinate reference.
  • Keep near and far ranges reasonable so depth precision and clipping do not hide objects unexpectedly.

Camera and lights

  • Treat the camera as an animated object with its own authored ownership. Avoid multiple branches writing camera transform at once.
  • Use lights to support the subject, not as decoration. Verify the scene still reads when color, exposure, or background changes.
  • When the camera responds to pointer or scroll input, limit the range so users do not lose the subject.

Interaction and verification

  • Check first frame framing, resize framing, and the full interaction range.
  • Verify depth ordering, occlusion, and pointer picking in the browser rather than relying only on source inspection.
  • Keep a non-interactive or reduced-motion path for scenes that otherwise require constant camera movement.

Working sample slot

3D scenes, cameras, and lights: This page reserves a sample location for a later verified example. Add the sample only after the source file, public page, validation output, and visual check all pass.
