我是 VisPy 的初学者。
我想做的就是:
单击该点,该点将改变颜色并打印该点的位置 (x,y,z)。
但我找不到如何做到这一点。
这是我的代码。
import numpy as np
import sys
from vispy import app, visuals, scene
class Canvas(scene.SceneCanvas):
""" A simple test canvas for testing the EditLineVisual """
def __init__(self):
scene.SceneCanvas.__init__(self, keys='interactive',
size=(800, 800), show=True)
# # Create some initial points
self.unfreeze()
# Add a ViewBox to let the user zoom/rotate
self.view = self.central_widget.add_view()
self.view.camera = 'turntable'
self.view.camera.fov = 30
self.show()
self.selected_point = None
scene.visuals.GridLines(parent=self.view.scene)
self.freeze()
def on_mouse_press(self, event):
print(event.pos) # How to convert this pos …Run Code Online (Sandbox Code Playgroud)
