Export
These examples get a sketch out of the window, four ways. They save the rendered frame as a raster image. They serialize the draw calls behind that frame to vector paths for a pen plotter, with hatching where a fill has to become line work. They plan those paths as a G-code toolpath for a machine, and draw the plan so you can see the route first. They also record a run as it plays, picture and sound together. See the Export reference.
| Example | What it shows |
|---|---|
| Capture | the frame-grab seam: an extension that saves the rendered frame to a PNG when you press S |
| VectorExport | SVG export: the shape catalog serialized to vector paths (--export-svg) |
| Hatching | filled shapes shaded as pen line work for a plotter (--export-svg --hatch) |
| Toolpath | the machine's route before anything moves: GCode.toolpath(_:in:) plans the line work, and the sketch draws that plan, with the paths in plot order, the pen-up travels between them, and a pen that moves along the route at machine speed |
| Embroidery | the stitches before the machine sews them: a leaf composed as contours, planned with Embroidery.stitches(_:in:), and drawn as its plan, with a dot at every penetration, the thread between them, the jumps, and a needle walking the plan at machine speed (--export-embroidery) |
| Drafting | the layers a shop program will open: a box panel drawn in three colors, cut, score, and engrave, each planned with DXF.drafting(_:in:) and listed beside the drawing with its entity count (--export-dxf) |
| LineDrawing | a 3D scene as line work a machine can follow: lineDrawing(of:) takes the meshes and the camera and gives back paths with what the surfaces hide taken out, with the crease angle, the test spacing, and the hidden stretches on parameters (--export-svg, --export-gcode) |
| LinearFrame | the frame before the tone map: --export-exr writes an OpenEXR file whose color runs past white where the highlights are, with the frame's coverage and the distance from the eye beside it, which is what a compositing program wants |
| Cutout | a piece that leaves its background behind: background(.clear) makes the canvas see-through, and the PNG, the sequence, and a proRes4444 or hevcWithAlpha clip keep the alpha, so it lands over another layer instead of over black |
| Record | a run recorded as it plays: R starts and stops a real-time take of picture and sound together, and the take is stamped with the wall clock, so a slow frame lasts longer instead of stretching time |
