BaseDraw.DrawArrayEnd(self)¶: Each DrawPolygon() puts the polygon into an internal array and draws the polygons when the array is full or an Viewport state changes (e.g. the matrix). With this method you can force this operation.

BaseDraw.DrawPolygonObject(self, bh, op, flags, parent=None, col=Vector(0.5))¶

Draws a polygon object into the view.

Parameters

bh (c4d.plugins.BaseDrawHelp) – Needs to be passed along.
op (c4d.BaseObject) – The object.

flags (int) –

Flags:

DRAWOBJECT_NONE	None.
DRAWOBJECT_FORCELINES	Force wireframe display, independent of view settings.
DRAWOBJECT_NOBACKCULL	Force no backface culling, independent of view settings.
DRAWOBJECT_LOCALMATRIX	Object will be drawn relative to the currently processed object (used when called from the Draw() function in an object.
DRAWOBJECT_EDITMODE	Object is drawn in edit-mode style.
DRAWOBJECT_FORCEBASE	The draw call is only executed for the base class, and thus not for the instanciated object, if passed to `BaseDraw.DrawObject()` and the object type is an instance of either Opoint or Opolygon. This way, a draw call can be invoked from points/polygons derived object without running into a recursion.
DRAWOBJECT_FORCEPOINTS	Force points display.
DRAWOBJECT_NO_EOGL	No Extended OpenGL.
DRAWOBJECT_USE_OBJECT_COLOR	Use the object’s color.
DRAWOBJECT_USE_CUSTOM_COLOR	Use a custom color.
DRAWOBJECT_XRAY_ON	Enables X-Ray mode.
DRAWOBJECT_XRAY_OFF	Disables X-Ray mode.
DRAWOBJECT_IMMEDIATELY	Draws an object immediately. Usually all objects are collected in a Z-depth sorted list before drawing. This flag is used for objects which are immediately deleted after drawing.
DRAWOBJECT_Z_OFFSET	Do not change the Z offset.
DRAWOBJECT_PRIVATE_ANY	Private.

parent (c4d.BaseObject) –

New in version R21.

This is used for the viewport filter.

Take the Floor object for example, it displays a polygon object in the viewport. If parent is set to None the drawn polygon is considered by the viewport filter.

If the Floor object has been passed to parent the Floor object is considered by the viewport filter instead.
col (c4d.Vector) –

New in version R21.

The object’s color.
