Hello Sir.
I am currently working on a project with pythonocc==7.5.1 where I am modeling a 2D object which can be written as multiple lines. I need to be able to do two things at the same time:
I tried two different methods, but neither satisfy both of the previous requirements:
Could you please give me any suggestions to be able to solve this issue? I thank you in advance for any insight you might provide!
Here is a simple example to demonstrate the issue I am having.
import numpy as np

from OCC.Core.gp import gp_Pnt
from OCC.Core.TopoDS import TopoDS_Wire

from OCC.Core.Geom import Geom_CartesianPoint
from OCC.Core.AIS import AIS_Line
from OCC.Core.Prs3d import Prs3d_LineAspect
def on_click(shapes, *kwargs):
if len(shapes) == 0:
# AIS LINE ARE NOT CAUGHT! Shape is an empty list
print("On click ===> Empty shape list!")
for shape in shapes:
if isinstance(shape, TopoDS_Wire):
# WIRES ARE CAUGHT HERE
print("On click ===> TopoDS_Wire!")
def display_lines_as_wires(lines):
for [x1,y1],[x2,y2] in lines:
wire = BRepBuilderAPI_MakeWire()
edge = BRepBuilderAPI_MakeEdge(gp_Pnt(x1, y1, 0), gp_Pnt(x2, y2, 0)).Edge()
wire.Add(edge)
display.DisplayShape(wire.Shape(), update=False, color="RED")
def display_ais_lines(lines):
width = 5.
color = Quantity_Color(13/255, 13/255, 203/255, Quantity_TOC_RGB)
for [x1,y1],[x2,y2] in lines:
ais_line = AIS_Line(
Geom_CartesianPoint(x1,y1,0),Geom_CartesianPoint(x2,y2,0)
)
drawer = ais_line.Attributes()
aspect = Prs3d_LineAspect(color, 0, width)
drawer.SetLineAspect(aspect)
ais_line.SetAttributes(drawer)
display.Context.Display(ais_line, False)
