The Binner project allows simple statistical analysis to be done on scattered points. It does this by placing the series of scattered points onto the nearest points of a uniform grid and counting the number of points at each grid node. The project can also count the number of points at each grid node that fall within specified data ranges.

The build3D user macro takes a series of 2D image files that represent layers of a 3D volume and builds them into 3D field data that can be visualized using the normal tools. This project has been superceded by the Build3D_2 project but is still available as an example of V script programming.

Authors: James Schumm, Paul G. Lever, Andrew Dodd Version: 1.1 Path: iac_proj/build3d/

The build3d_2 user macro takes a series of 2D image files that represent layers of a 3D volume and builds them into 3D field data that can be visualized using the normal tools. The Build3D_2 project is intended to replace the old Build3D project and has been rewritten so that it reads image files and builds volume data using C code. This greatly improves the performance and reliability of the module and removes the dependance upon the Developer's Edition of AVS/Express. This version adds basic support for colouring field nodes with the image data.
