I was able to fix it, temporarily at least, by replacing line 431 in visMPL.py
,
ax = Axes3D(fig)
to
ax = fig.add_subplot( 111, projection='3d' )
Thank you! Same problem and this also solve my issue :)
Same and solved. Also, for anyone having the error that np.float
is deprecated, just replace with the inbuilt float
type as NumPy prompts and you're good.
ax=Axes3D(fig);fig.add_axes(ax)
Describe the bug I want to create NURBS/Bezier Surfaces with geomdl. I installed the package via conda and started by trying to run the example given here : https://nurbs-python.readthedocs.io/en/5.x/visualization.html
This is the given code: `from geomdl import BSpline from geomdl.visualization import VisMPL
ctrlpts = [ [[-25.0, -25.0, -10.0], [-25.0, -15.0, -5.0], [-25.0, -5.0, 0.0], [-25.0, 5.0, 0.0], [-25.0, 15.0, -5.0], [-25.0, 25.0, -10.0]], [[-15.0, -25.0, -8.0], [-15.0, -15.0, -4.0], [-15.0, -5.0, -4.0], [-15.0, 5.0, -4.0], [-15.0, 15.0, -4.0], [-15.0, 25.0, -8.0]], [[-5.0, -25.0, -5.0], [-5.0, -15.0, -3.0], [-5.0, -5.0, -8.0], [-5.0, 5.0, -8.0], [-5.0, 15.0, -3.0], [-5.0, 25.0, -5.0]], [[5.0, -25.0, -3.0], [5.0, -15.0, -2.0], [5.0, -5.0, -8.0], [5.0, 5.0, -8.0], [5.0, 15.0, -2.0], [5.0, 25.0, -3.0]], [[15.0, -25.0, -8.0], [15.0, -15.0, -4.0], [15.0, -5.0, -4.0], [15.0, 5.0, -4.0], [15.0, 15.0, -4.0], [15.0, 25.0, -8.0]], [[25.0, -25.0, -10.0], [25.0, -15.0, -5.0], [25.0, -5.0, 2.0], [25.0, 5.0, 2.0], [25.0, 15.0, -5.0], [25.0, 25.0, -10.0]] ] surf = BSpline.Surface()
surf.degree_u = 3 surf.degree_v = 3
surf.ctrlpts2d = ctrlpts
surf.knotvector_u = [0.0, 0.0, 0.0, 0.0, 1.0, 2.0, 3.0, 3.0, 3.0, 3.0] surf.knotvector_v = [0.0, 0.0, 0.0, 0.0, 1.0, 2.0, 3.0, 3.0, 3.0, 3.0]
surf.delta = 0.025
surf.evaluate()
from matplotlib import cm
surf.vis = VisMPL.VisSurface() surf.render(colormap=cm.cool)`
The code runs with without an error.
Expected Behavior It should look like this: But it just looks like this:
The example in 2D work without a problem but as soon as i try to plot a Curve or Surface in 3D it shows an empty figure.
Configuration:
It would be really appreciate your help.
