This requires - rotating them, which can be achieved by specifying rotation quaternion to each item: - - \snippet rotations/scatterdatamodifier.cpp 0 - \snippet rotations/scatterdatamodifier.cpp 1 - \snippet rotations/scatterdatamodifier.cpp 2 - - Since the items need to be rotated along two axes, we define two rotation quaternions, one - for Y-axis and one for Z-axis, and then multiply these together to get the total rotation, - which we set to the data item. - - \section1 Using Custom Item Meshes - - The narrow arrow mesh we use for magnetic field arrow items is not a standard mesh. Instead - we supply our own \c{narrowarrow.obj} file which contains the object definition for the mesh - in \c Wavefront obj format: - - \snippet rotations/scatterdatamodifier.cpp 3 - - \section1 Using Range Gradient - - Setting the color style to range gradient in a series means that the item is colored according - to its relative Y-value on the visible Y-coordinate range. We want the arrows on the bottom - part of the graph to be darker and gradually get lighter higher they are, so we define a - range gradient with black color at the position 0.0 and white color at the position 1.0: - - \snippet rotations/scatterdatamodifier.cpp 4 - - \section1 Example Contents -*/ |
