Vector Tile Roadmap #25

Open pjcozzi opened 8 years ago

pjcozzi commented 8 years ago

Notes on vector data

[x] Polygons, #24
- [ ] How bad are cracks and what are we going to do about them?
- [ ] Can additive refinement just add new vertices to polygons? Perhaps this is a completely different progressive tile format.
- [ ] Per-feature minimumHeight and maximumHeight?
[x] Polylines
[ ] Polygons with holes
[ ] Declarative styling
[ ] Point features - billboards, labels, and points
- [ ] Declutter?
[ ] Non clamped-to-ground features
[ ] Concise representation for ground-clamped positions, https://github.com/AnalyticalGraphicsInc/3d-tiles/pull/124#issuecomment-243156631

Selection of Cesium geometries:

[ ] Polygon: extrusion and at height
[ ] Polyline: extrusion (wall) and at height
[ ] Rectangle: on terrain, extrusion, and at height
[ ] Ellipse: on terrain, extrusion, and at height
Others as requested

Initial Cesium implementation for polygons: https://github.com/AnalyticalGraphicsInc/cesium/pull/4186

pjcozzi commented 7 years ago

Started spec in #124.

Pushing post 1.0 to narrow the scope, this would come soon after in a follow-up spec release since the spec and Cesium implementation are far along.

[ ] In declarative styling, should point.image be able to reference pixels glTF buffer/bufferView style?

pjcozzi commented 6 years ago

[ ] Ability to change polyline width (and other polyline properties) via declarative styling

pjcozzi commented 6 years ago

[ ] Polyline style

pjcozzi commented 6 years ago

[ ] What classification volumes - and other higher order surfaces like ellipses - should be able to be just rendered like polygons - as opposed to used for classifying another tileset?

ggetz commented 6 years ago

Suggestion from the forum: https://groups.google.com/forum/#!topic/cesium-dev/3zTt9rZVX08

Ability to style what happens when geometries intersect or overlap (for instance, when two points overlap, ability to define the resulting overlap color)

[ ] Make polyline heights optional. When heights are omitted the polyline should be clamped to the surface by the client.

lilleyse commented 5 years ago

[ ] Support textured polygons.

jailln commented 3 years ago

Hello, Do you have an idea on when the vector tile format will be available in 3D Tiles ? Thanks :)

rory-ye-nv commented 3 years ago

when will this be available? we are waiting for this important feature

lilleyse commented 2 years ago

See https://github.com/CesiumGS/3d-tiles/issues/391 for floating point precision considerations.
