Effect › 3D and Materials › 3D (Classic) › Revolve (Classic)… sweeps the
profile round a vertical axis, as Revolve does, and draws every face with
the Wireframe, No Shading, Diffuse and Plastic surfaces of Extrude & Bevel
(Classic).
- `effect.apply` with `threeD.classicRevolve`: Angle (0 to 360), Cap,
Offset (0 to 1000 pt) from the left or right edge of the profile's
bounds, the Position rotation and Perspective, and the classic lights,
Ambient Light, highlight, Blend Steps and Shading Color.
- Groups and layers revolve about one shared axis, and the effect also
goes on a fill or stroke, as Revolve's does.
- `effect.lightingPreset` refuses it, as it refuses Extrude & Bevel
(Classic).
- Revolve faces carry their view-space normal, and
`three_d::revolve_facets` hands them to the classic surface code.
- Unknown parameters, numbers out of range and bad flags, edges,
surfaces and colors are refused with an error.
revolve_curve_samples counted a profile's contours but never compared the count with the limit,
so a profile made only of empty or one-anchor subpaths passed, although each contour takes one
profile point. HoleSearch::new then built one entry for each subpath without a limit, and mesh
export skips revolve_curve_samples when curve_samples is given. Both now refuse a profile with
more than 16,384 contours as too complex.
Mesh export tested the middle of every segment against every closed contour's bounds, so a profile of thousands of separate contours took hundreds of millions of comparisons before the work limit counted any. The closed contours now go in a grid over their bounds, a point is tested only against the contours of its cell, and placing a contour in a cell and each candidate looked at count toward the limit.
Type sweeps as its glyph outlines and stays editable. On a group or layer every visible member sweeps about one axis on the edge of the members' bounds together, each in its own paint.
A surface now takes up to 16,384 profile points and 163,840 faces. Curves take fewer samples, down to 4, when a surface passes those limits, and the command reports the failure below that, after the geometry effects before the Revolve and with the cumulative size of its paint copies counted. Mesh export turns the walls of holes toward them. Expand Appearance works on type with Extrude as well as Revolve.
Fixes#3617
Effect > 3D and Materials > 3D (Classic) > Extrude & Bevel (Classic)... applies
`threeD.classicExtrude`, a live effect built on the Extrude & Bevel solid. It
takes Extrude Depth, Cap, a bevel with Height and Bevel Extent In or Out, the
Position presets, rotation and Perspective, and draws the faces with the
Wireframe, No Shading, Diffuse or Plastic surface: one to ten lights, Ambient
Light, Highlight Intensity and Size, Blend Steps, a Black, Custom or no Shading
Color, and Draw Hidden Faces. Invalid parameters are refused with an error.
