3D Graphics Examples
Here are some pretty pictures generated using the PDL::Graphics::TriD module, follow the links to get full-size pictures and the PDL code which produced them.
Note when displayed with PDL viewing from different angles is as simple as rotating the figure with the mouse!

2D & 3D Graphics Examples
PLplot is a scientific plotting library for 2D and 3D graphics. PLplot has a rich API allowing fine control of every aspects of the plots. The PDL binding for PLplot (in PDL::Graphics::PLplot) comes in two flavors: a high-level, object-oriented interface and a low-level interface which is very close to the C API of the library. The demos distributed with PLplot have been ported to the low-level interface and are available at the PLplot examples area (two examples are shown below).
Image Distortion Example
Image resampling and co-alignment is handled by the PDL::Transform package. Here is an example of a nonlinear coordinate transformation applied to an image of the space shuttle. The image is being rotated in logarithmic azimuthal space. The transformation is continuous everywhere except on a singular ray extending upward from the origin. The PDL::Transform code includes optimized resampling to prevent introducing artifacts into your data. You can tell that it's at work by comparing the sampled and anti-aliased movies. Here is the brief script that generated the frames.
