Web7 de ago. de 2024 · edit The problem lays in how you expect the 3D-mesh points to be ordered with respect to your data. You can match your data dz to the meshgrid by switching your third axis with the second: plot_3d_quiver (xi [skip3D], yi [skip3D], zi [skip3D], dx, dy, np.moveaxis (dz,2,1)) Or, if you'd use two dimensions only, you can transpose the matrix: Web1 de nov. de 2015 · In order to achieve this, we first ask users to specify desired features by manually segmenting a few streamlines from a flow field. Users only need to pick the segmentation points (i.e., positive examples) along a streamline, remaining points will be used as negative examples.
WebThereby, the minimization problem can be solved locally per pixel, making it possible to combine all geometry types (points, lines and surfaces) consistently in a single optimization framework. We call this decoupled opacity optimization and apply it to a number of steady 3D vector fields.
