draw text labels at 2D dataset points
<p>
<a class="el" href="a00442.html" title="draw text labels at 2D dataset points">vtkDynamic2DLabelMapper</a> is a mapper that renders text at dataset points such that the labels do not overlap. Various items can be labeled including point ids, scalars, vectors, normals, texture coordinates, tensors, and field data components. This mapper assumes that the points are located on the x-y plane and that the camera remains perpendicular to that plane with a y-up axis (this can be constrained using vtkImageInteractor). On the first render, the mapper computes the visiblility of all labels at all scales, and queries this information on successive renders. This causes the first render to be much slower. The visibility algorithm is a greedy approach based on the point id, so the label for a point will be drawn unless the label for a point with lower id overlaps it.<p>
<dl class="warning" compact><dt><b>Warning:</b></dt><dd>Use this filter in combination with <a class="el" href="a01528.html" title="extract points that are visible (based on z-buffer calculation)">vtkSelectVisiblePoints</a> if you want to label only points that are visible. If you want to label cells rather than points, use the filter <a class="el" href="a00244.html" title="generate points at center of cells">vtkCellCenters</a> to generate points at the center of the cells. Also, you can use the class <a class="el" href="a00719.html" title="generate scalars or field data from point and cell ids">vtkIdFilter</a> to generate ids as scalars or field data, which can then be labeled.</dd></dl>
