C++ How To
Often you just need a "pointer" to an example that shows you how to do something.
Here are some snippets or examples that highlight interesting features that may help you:
Read in a Polydata file
| Example Name | Comments | Image |
|---|---|---|
| ReadPolyData | This snippet works for most PolyData. |
Write out an image
| Example Name | Comments | Image |
|---|---|---|
| WriteImage | Write out an image of various types. |
Camera
| Example Name | Comments | Image |
|---|---|---|
| MergeSelections | Use the same camera for all renderers. | |
| ShareCamera | Use the same camera for all renderers. |
Coloring
| Example Name | Comments | Image |
|---|---|---|
| KochanekSplineDemo | How to color the slider components. | |
| MergeSelections | A nifty way to get a "harmonious" set of window colors, using vtkNamedColors and vtkColorSeries. | |
| ShareCamera | Store background colors in a vector for later extraction of the red, green and blue components. |
Glyphing
| Example Name | Comments | Image |
|---|---|---|
| QuantizePolyDataPoints | Represent a point by a glyph. |
Render Windows
| Example Name | Comments | Image |
|---|---|---|
| Model | Multiple render windows. |
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.
| Example Name | Comments | Image |
|---|---|---|
| ColorDisconnectedRegionsDemo | A vtkLookupTable is filled with random colors. | |
| HighlightWithSilhouette | Here we use randomly positioned spheres with random colors. A vtkLookupTable is filled with random colors. |
