class vispy.visuals.filters.base_filter.BaseFilter#

Bases: object

Superclass for all filters.

class vispy.visuals.filters.base_filter.Filter(vcode=None, vhook='post', vpos=5, fcode=None, fhook='post', fpos=5)#

class vispy.visuals.filters.base_filter.PrimitivePickingFilter(fpos=9, *, discard_transparent=False)#

Bases: Filter

Abstract base class for Visual-specific filters to implement a primitive-picking mode.

Subclasses must (and usually only need to) implement _get_picking_ids().
