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.

class v_sim.SurfaceIterPoly¶

Structures used to iterate on polygons of surf.

New in version 3.8.

addInvertedVertices(vertices)¶

Parameters:: vertices ([float]) – an array to store the vertex coordinates and normals.

Like v_sim.SurfaceIterPoly.addVertices(), but using normal vectors pointing in the opposite direction.

New in version 3.9.

addVertices(vertices)¶

Parameters:: vertices ([float]) – an array to store the vertex coordinates and normals.

Retrieve the position and normal of the point refered by self, using the v_sim.GlExtPackingModels.XYZ_NRM layout.

New in version 3.9.

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(view)¶

Parameters:

view (v_sim.GlView) – the v_sim.GlView the surface is projected to.

Returns:

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

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.
