Basic Package
From a reconstructed geometry or from any imported 3D data, including time series, the Basic Amira Package delivers a wide range of visualization techniques and interactive manipulation capabilities. Through a comprehensive set of 3D post-processing tools, it offers a highly flexible and powerful 3D visualization and simulation platform.
Platforms
Windows 32-bit, Windows 64-bit, Mac OS, Linux
Features
Analyze and Quantify
Analyze your volumes with advanced tools for statistical, surface and grid analysis. Interactively perform geometrical measures of distances, angles, surface and volumes. Link Amira with MATLAB to perform simulation and advanced numerical analysis.
- Material statistics
- Volume and surface measurement
- 2D/3D linear measurement and annotation
- Co-localization analysis
- Arithmetic operations
- Densitometry
- Surface analysis Integration of MATLAB® engine (Win and Linux only)
- Network statistics
