The presence of a third dimension makes accurate drawing in virtual reality (VR) more challenging than 2D drawing. These challenges include higher demands on spatial cognition and motor skills, as well as the potential for mistakes caused by depth perception errors. We present Multiplanes, a VR drawing system that supports both the flexibility of freehand drawing and the ability to draw accurate shapes in 3D by affording both planar and beautified drawing. The system was designed to address the above-mentioned challenges. Multiplanes generates snapping planes and beautification trigger points based on previous and current strokes and the current controller pose. Based on geometrical relationships to previous strokes, beautification trigger points serve to guide the user to reach specific positions in space. The system also beautifies user's strokes based on the most probable intended shape while the user is drawing them. With Multiplanes, in contrast to other systems, users do not need to manually activate such guides, allowing them to focus on the creative process.
