surface2volume

Convert a volume defined by a surface to a binary 3D block.

Description

First the surface will be rasterized on the grid. Therefore it calculates the position of points which lie in the surface in a finer resolution as defined by the inputgrid. These points were then tranfered to the point it the inputgrid by using a simple indexing technique. One could also use dsearchn, but this takes to much computational time, however, it can avoid the need of an equidistant grid. After rasterizing the patches the background is fill using imfill. The start point is set to the lower left corner. Afterwards the data block will be inverted. The script tests if the datablock is fully filled and tries to repeat the task slice by slice.

very very good.

[thevan S]

Very good and help full

[Carlos Platero]

I need 3D models

[Sebastian H]

Amazing! Fast and reliable. Many, many thanks.

A hint: I had to change the outputFID from 0 to 1, Matlab 7.6 R2008a seems not to accept zero file identifiers for fprintf.

nice tool,
but it confuses x with y coordinates in line 172

[Alex Kararg]

Given only the x,y,z coordinates of a surface S how does this function work?

[Steve]

I would also like to know how to use it with data in (x,y,z) format. Can you please tell me?
