Fields

Name	Type	Access	Description
i	int	r/w	the index of the current polygon.
points	v_sim.SurfacePoints	r/w	the storage for polygons.
surf	v_sim.Surface	r/w	the parent v_sim.Surface.
valid	bool	r/w	a flag True, as long as the iterator is valid.

Details

class v_sim.SurfaceIterPoly

Structures used to iterate on polygons of surf.

New in version 3.8.

getVertices(vertices)

Parameters:

vertices ([v_sim.SurfacePoint]) – an array to store the vertex coordinates and normals.

Retrieve the position and normal of the point refered by self.

New in version 3.8.

getZ(mat)

Parameters:

mat (float) – a transformation matrix to go into viewport basis.

Returns:

True if polygon defined by self is drawn and z is computed

z:

a location to store double.

Return type:

(bool, z: float)

Retrieve the z value in the viewport basis of the drawn polygon defined by self. If the polygon is not drawn, z is not computed.

New in version 3.8.

next()

Iterate to the next drawn polygon.

New in version 3.8.
