You can mark up the heightfield with polyline and spline shapes, as a visualization aid or as a modeling assist.
Use vector shapes to annotate, to add local texture detail, and to easily fill areas with objects. Illustrator-style controls let you easily create markers (points), lines, polygons, circles and arbitrary curves. You can also obtain raster selection masks from vector shapes for precision modeling. Elevated shapes let you work with contour lines and quickly create heightfield formations. Import shapes from GDAL-supported formats and Adobe Illustrator, and export to DXF, Illustrator, and to SVG.
- Tools similar to Adobe Illustrator for easy learning.
- Extract heightfield selection mask from selected shapes.
- Assign fill color/opacity, stroke color/opacity, and stroke width to selected shapes.
- Distribute 3D objects within a shape's fill and/or along its stroke.
- Feather shape content to smoothly merge with underlying ground color or other shapes.
- Assign optional elevation to selected shapes.
- Extract convex hull from selected shapes (e.g., contour line rasterization).
- Extract contour lines from heightfield into elevated polyline shapes.
- Import vector shapes from Illustrator and through GDAL (DXF, ESRI, TIGER/LINE, etc.).
- Make heightfield formations from elevated shapes.
- Export vector shapes to Illustrator, DXF, and SVG.
- Cut, join, and align shape points.
- Paste in front/back, send shapes forward/backward or to the front/back.
- Annotate shapes with optional names and text notes.
- Tesselate, simplify, and insert points into selected shapes.
- Use shapes to create smooth flyover animation camera flight and look-at paths.
- View shapes in high resolution with auto-LOD renderer or when raytracing.
