三维数据成像软件3D Surfer主要用于地质、工程、科学计算等数据的三维可视化成像显示。它支持两种成像方式：体成像和等值面成像。利用3D Surfer可以将数据在三维空间进行三维可视化显示，并且具有图形旋转、图形放缩、三维虚拟漫游、分层显示、图形切割、制作切片等功能。3D Surfer 2.0 支持Surfer切片图、高程模型图、曲折剖面、透明图层、叠加地形、贴图等功能。3D Surfer采用类似Surfer的操作方式，兼容Surfer定义的文本数据格式和GRD数据格式。支持规则数据和散乱数据的三维插值，与Surfer软件定义的色标等级文件兼容，支持*.lvl和*.clr的颜色等级文件，支持*.dat *.txt *.grd等数据格式。支持三维图像的输出转换，可以将三维图形转换为虚拟现实数据文件VRML数据格式、JPG、BMP等图形格式输出等。

The gridding methods in Surfer allow you to produce accurate contour, surface, wireframe, vector, image, and shaded relief maps from your XYZ data. The data can be randomly dispersed over the map area, and Surfer's gridding will interpolate your data onto a grid. You have a multitude of gridding methods to choose from, so you can produce exactly the map you want. With each gridding method you have complete control over the gridding parameters. If your data are already collected in a regular rectangular array, you can create a map directly from your data. Computer generated contour maps have never been more accurate.

Gridding Features

Interpolate from up to 1 billion XYZ data points (limited by available memory)
Produce grids with up to 100 million nodes
Specify faults and breaklines when gridding
Choose from one of the powerful gridding methods: Inverse Distance, Kriging, Minimum Curvature, Polynomial Regression, Triangulation, Nearest Neighbor, Shepard's Method, Radial Basis Functions, Natural Neighbor, Moving Average, and Local Polynomial
Specify isotropic or anisotropic weighting
You have full control over the grid line geometry including grid limits, grid spacing, and number of grid lines
Customize search options based on user-defined data sector parameters
Specify search ellipses at any orientation and scaling
Use spline smoothing and grid filtering to alter the grid file
Use grid math to perform mathematic operations between grid files
Use Nearest Neighbor to create grid files without interpolation
Use Triangulation to achieve accuracy with large data sets faster
Detrend a surface using Polynomial Regression, generate regression coefficients in a report, and calculate residuals
Use data exclusion filters to eliminate unwanted data
Use duplicate data resolution techniques
Generate a grid of Kriging standard deviations
Specify point or block Kriging
Generate a report of the gridding statistics and parameters including ANOVA regression statistics
Specify scales and range for each variogram model
Extract subsets of grids or DEMs based on rows and columns
Transform, offset, rescale, rotate, and mirror grids
Calculate first and second directional derivatives at user-specified orientations
Calculate differential and integral operators utilizing gradient, Laplacian, biharmonic, and integrated volume operators
Analyze your data with Fourier and spectral analysis with Correlograms and Periodogram
Generate grids from a user-specified function of two variables
Calculate grids with Data Metrics including: number of points within search ellipse, distance to nearest and farthest neighbor, median, average and offset distance to points within the search ellipse
Use cross-validation to judge the suitability of the gridding method for the particular data set
