摘要: We present "JustDrawIt", a sketch-based system for creating 3D curves suitable surfacing. The user can sketch in free-form manner from any view at time, and the infers how those strokes should be added to drawing. Specifically, existing are projected 2D analyzed see if stroke edits or extends an curve, make new curve. In former case is promoted using position of then joined that latter case, we use additional spatial information (e.g. temporary surfaces) create curve 3D. All non-sketching interactions based on unintrusive context-aware, in-screen pie menus designed rapid pen-based input. also provide novel rendering styles aides interpreting working with sketches. Finally, support snapping together networks specifying normals order surface models.
