C++ How To Often you just need a "pointer" to an example that shows you how to do something.
Here are some snippets and examples that highlight interesting features that may help you:
Callback Example Name Comments Image CallBack Setting up a callback with client data. Two different methods are demonstrated.
Camera Coloring Glyphing Image Example Name Comments Image WriteImage Write out an image of various types.
Multiple view ports and render windows Polydata Example Name Comments Image ReadPolyData This snippet works for most PolyData.
Random If you want to ensure that the same random points/colors are used in C++ and other languages then it is best to use vtkMinimalStandardRandomSequence .
Render Windows Example Name Comments Image Model Multiple render windows.
StructuredDataset How to visualise the information in a structured dataset. All these examples use the combustor dataset.
Example Name Comments Image ColorIsosurface Color an isosurface with a data array. CombustorIsosurface Generate an isosurface of constant flow density. CutStructuredGrid Cut through structured grid with plane. The cut plane is shown solid shaded. A computational plane of constant k value is shown in wireframe for comparison. The colors correspond to flow density. Cutting surfaces are not necessarily planes: implicit functions such as spheres, cylinders, and quadrics can also be used. ProbeCombustor Probing data in a combustor. Probes are regular arrays of 50 by 50 points that are then passed through a contouring filter. PseudoVolumeRendering Here we use 100 cut planes, each with an opacity of 0.05. They are then rendered back-to-front to simulate volume rendering. Rainbow Using different vtkLookupTables. StreamLines Seed streamlines with vectors from a structured grid. StreamlinesWithLineWidget Interact with the streamlines in the combustor dataset. VelocityProfile Warping the geometry of three planes to show flow momentum. WarpCombustor Carpet plots of combustor flow energy in a structured grid. Colors and plane displacement represent energy values. XYPlot Display line probes.
