c4d.CPolygon¶

class c4d.CPolygon¶: Represents a polygon.

Attributes

c4d.CPolygon.a¶

Index of first point in the polygon.

Type: int

c4d.CPolygon.b¶

Index of second point in the polygon.

Type: int

c4d.CPolygon.c¶

Index of third point in the polygon.

Type: int

c4d.CPolygon.d¶: Index of optional fourth point in the polygon.

Overview¶

Magic Methods
`CPolygon.__init__()`
`CPolygon.__str__()`	Returns a string representation of the polygon object.
Shape And Topology
`CPolygon.EdgePoints()`	Retrieves the point indices for edge.
`CPolygon.Find()`	Checks if one of the polygon vertex indices is equal to index and returns the found polygon vertex number (0-3, equals `a` - `d`).
`CPolygon.FindEdge()`	Checks if the vertex indices index1 and index2 form an edge in this polygon.
`CPolygon.IsTriangle()`	Checks if the polygon is a triangle.

Magic Methods¶

CPolygon.__init__(self, t_a, t_b, t_c, t_d)¶

Parameters

t_a (int) – Index of first point in the polygon.
t_b (int) – Index of second point in the polygon.
t_c (int) – Index of third point in the polygon.
t_d (int) – Index of optional fourth point in the polygon.

CPolygon.__str__(self)¶

Returns a string representation of the polygon object.

Called if str() is invoked on a CPolygon object. See object.__str__() for more information on Python’s data model.

Return type: str
Returns: The string representation of the polygon.

Shape And Topology¶

CPolygon.EdgePoints(self, edge)¶

Retrieves the point indices for edge.

New in version R16.021.

Parameters: edge (int) – The edge index (0-3).
Return type: Tuple[int, int]
Returns: The index of the first and second edge point.

CPolygon.Find(self, index)¶

Checks if one of the polygon vertex indices is equal to index and returns the found polygon vertex number (0-3, equals a - d).

New in version R16.021.

Parameters: index (int) – The vertex index to check.
Return type: int
Returns: The matching polygon vertex number (0-3, equals a - d). NOTOK is returned if there is no match.

CPolygon.FindEdge(self, index1, index2)¶

Checks if the vertex indices index1 and index2 form an edge in this polygon. If so the polygon edge number is returned (0-3).

New in version R16.021.

Parameters

index1 (int) – The vertex index of the first edge point.
index2 (int) – The vertex index of the second edge point.

Return type

int

Returns

The found polygon edge number (0-3). NOTOK is returned if there is no match.

CPolygon.IsTriangle(self)¶

Checks if the polygon is a triangle.

New in version R16.021.

Return type: bool
Returns: True if the polygon is a triangle, otherwise False.

Category	Option	Description
Query	Words and phrases	Search is case-insensitive. Put a phrase in quotes for an exact match. Quoted phrases require every word and disable fuzzy matching.
Terms	OR / AND	Choose whether to match any term or require all terms.
Fuzzy	On / Off	Toggle approximate and prefix matches. Quoted phrases always use strict matching.
Results	Sparse / Dense	Sparse groups multiple hits for one entity and hides its owned API members when the class or module itself matches. Dense lists each match separately.
Sort by	Type / Relevance	Group results by entity type then rank within each group, or rank all results by relevance.
Content	All / API / Manuals / Examples / Resources	Search all documentation, API documentation, manuals, the examples index, or the resources index. Code examples embedded in other sections retain their own content area.
Entity	All / Page / Module / Class / Function / Attribute / Description / Node / Symbol / Icon	Page covers results without a specific entity type. Resource entity types are available with All or Resources; API entity types are available with All or API.
Location	All / Text / Code / Name / Signature	Text covers everything outside code, names, and signatures. Name and Signature are available with All or API.
