Hi, just learning pyqtgraph this weekend.
How to do so that the object is of reasonable size? See minimal code below;
the mesh created is there but is so small is difficult to find it and see
it.
import numpy as np
from pyqtgraph.Qt import QtCore, QtGui
import pyqtgraph as pg
import pyqtgraph.opengl as gl
from readtecplot import *
app = QtGui.QApplication([])
w = gl.GLViewWidget()
w.show()
w.setWindowTitle('Testing, testing : GLMeshItem')
verts = np.array([
