How does one use 2 (or more) scalar fields in a dataset, e.g. one for a colormap, one to scale glyphs? E.g., Pgmable Source:
pdo = self.GetPolyDataOutput()
num_pts = 2
newPts = vtk.vtkPoints()
cell_color_ID = vtk.vtkFloatArray()
cell_radius = vtk.vtkFloatArray()
cell_color_ID.SetName('cell_color_ID')
cell_radius.SetName('cell_radius')
newPts.InsertPoint(0, -1,0,0)
cell_color_ID.InsertNextValue(1)
cell_radius.InsertNextValue(0.2)
newPts.InsertPoint(1, 1,0,0)
cell_color_ID.InsertNextValue(2)
cell_radius.InsertNextValue(0.3)
pdo.SetPoints(newPts)
pdo.GetPointData().SetScalars(cell_color_ID)
pdo.GetPointData().SetScalars(cell_radius) # overrides the 1st
verts = vtk.vtkCellArray()
for idx in range(0, num_pts):
verts.InsertNextCell(1)
verts.InsertCellPoint(idx)
pdo.SetVerts(verts)
