SDL Component Suite - Plot3D

The unit PLOT3D displays data as three-dimensional colored surfaces which can be rotated on-screen. The rotation of the data can be achieved either by mouse interaction or by using built-in methods of the class. The data can be viewed from any direction, and can be zoomed and panned. Looking at the surface from above creates a color contour plot. More details can be found in the online help pages.

The unit PLOT3D is part of the SDL Component Suite.


Tips, Tricks and Applications

Delphi Bits Rotatable 3D surface plot How to create a rotatable 3D surface plot with a minimum of efforts.
SDL TechNotes Plot3D Rotates upon Selection from Dialog How to cope with misguided mouse clicks.
DataLab Plot3D is used by DataLab If you want to experiment with a full-featured real-world application of Plot3D you may want to download the evaluation copy of DataLab. After installing it, load the data file "plot3d_dlab.asc" (command "File/Load/ASC Format...") and click the command "Visualization/3D Surface Plot". Although the evaluation copy is restricted to a maximum of 500 data points, you'll get a first impression (hint: try to change a few data points in the data editor).
