The preferred technique for displaying 'colors' and 'opacity' in this case would be to apply a transfer function (aka lookup table in OpenGL lingo) to map the luminance values to RGBA values. This can be done using the vzTMLUTShader which applies the lookup table (specified using a vzParameterLookupTable) to the volume data (specified using a vzParameterVolumeTexture). An example of this can be seen in the /usr/share/Volumizer2/data/XML/binary.vz XML file which uses a raw binary data set and applies a transfer function to it. Please send us your XML file if you are still having trouble with this. Cheers, Praveen P.S.

I mean this can be called an "interactive volume contrast" only for rendering purposes (don't need to save results) I've 2 questions: how can I do it? I need to modify and update the volume? does volumizer (version 2.3) provide function to work directly on the volume or I've (probably) to work on data source? Can I contrast my data source and then trigger a "volume reload"? I know I can change only the volumetric data set by using the vzParameterVolumeTexture::setDataPtr() method, as Praveen tough me several months ago. Volumizer will internally mark the data set as "dirty" and the new data set provided by the application will be loaded the next time the volume data set is rendered. So I need also to trigger a new render manually?

Since downloading a new LUT is much faster than downloading the complete volume, this would be interactive as well. The TFEditor that ships with Volumizer demonstratesthis functionality by providing a slider to adjust the contrast level of the volume using a LUT. Modifying the whole volume data is only necessary if you want to change the volume data in a way that cannot be accomplished by using LUTs. See the programming guide for more details on implementation details.

The BinLoader is written so that you can load a single 3D volume data file from disk. To load multiple files, you would need to do something like - // Read numSlices images into one buffer. for(int i =0; i < numSlices; i++) { // Open file i BinLoader *loader = BinLoader::open(filenames[i], headerSize, dim, format, type); if(!loader){ cerr<<"Could not open file "<loadBrick(data + i*sliceSize, pos, dim); // delete the loader. This would close the file. delete loader; } As for the maximum argument list, I think that it is a system parameter that you can query using 'getconf ARG_MAX'. If you are trying to pass the filenames using command line arguments, an alternative solution might be to use patterns, similar to the one used in /usr/share/Volumizer2/src/conv/tv/makeVol utility. hth, Praveen ----- Original Message ----- From: "Yi Mu" To: Sent: Tuesday, May 11, 2004 7:43 PM Subject: [info-volumizer] Re: Bin Loader > > > Hi, all > > Can anybody tell me how to use BinLoader to load multiple files? it > > looks I can only load in one file once. > > Another question, how to deal with the "arg list too long" problem, I only > > try to load less than 300 files and i got this error message, how the > > BinLoader will be useful if you can only load this less number of files? > > > > I am using Volumier2.3. > > Thanks , > > > > Yi Mu > > > > From info-volumizer-owner@els.sgi.com Wed May 12 02:05:59 2004 Received: (from majordom@localhost) by els.sgi.com (8.12.10/8.12.2/els-2.2) id i4C91Hht5183518; Wed, 12 May 2004 02:01:17 -0700 (PDT) Received: from nicte.si-tech.com.pl (pb165.pabianice.sdi.tpnet.pl [217.99.159.165]) by els.sgi.com (8.12.10/8.12.2/els-2.2) with ESMTP id i4C8ku1U5207735 for ; Wed, 12 May 2004 01:47:12 -0700 (PDT) Received: from octane.si-tech.com.pl ([192.168.1.88] helo=si-tech.com.pl) by nicte.si-tech.com.pl with esmtp (Exim 3.36 #1) id 1BNxc7-0003mF-00 for info-volumizer@els.sgi.com; Wed, 12 May 2004 10:33:51 -0700 Message-ID: <40A1E198.8010505@si-tech.com.pl> Date: Wed, 12 May 2004 10:34:32 +0200 From: Rafal Kaminski User-Agent: Mozilla/5.0 (X11; U; IRIX64 IP30; en-US; rv:1.6a) Gecko/20031101 X-Accept-Language: en-us, en MIME-Version: 1.0 To: info-volumizer@els.sgi.com Subject: [info-volumizer] Stero viewing in volumizer 2.5 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: owner-info-volumizer@els.sgi.com Precedence: bulk Reply-To: info-volumizer@els.sgi.com Hi all, Does stereo viewing need any special tricks in volumizer 2.5 ?

Of course, you would need to render the volume data twice for the left and right buffers using slightly different transformation matrices. The samples under /usr/share/Volumizer2/src/apps/simple/tmRenderAction can be made to run in stereo mode using the -stereo command line. I am told that these examples do not work very well in stereo though :( You should be able to look at the sources under /usr/share/Volumizer2/src/apps/simple/common to get the basic idea. Can you give more information about what issues you are having with the Space Ball? How are you scaling and translating the volume data? - Praveen ----- Original Message ----- From: "Rafal Kaminski" To: Sent: Wednesday, May 12, 2004 2:04 PM Subject: [info-volumizer] Stero viewing in volumizer 2.5 > Hi all, > > Does stereo viewing need any special tricks in volumizer 2.5 ? > Any example code ? > > I also have some problem with scale and move doing by the SpaceBall, > rotating of objects is OK. > Sensitivity is rather OK because the same code works in other > applications... > Any restrictions with using the SpaceBall ? > > Thaks in advance, > > Regards, > > > R.K.

You can subdivide the volume into multiple separable objects and render them using the XML file interface since it allows specifying multiple shapes in one file. An example is illustrated in the twoVolumes.vz file installed under /usr/share/Volumizer2/data/XML directory. Also see the chapter 8 in the programming guide for more details. To accomplish what you are trying to do, you will need to create two separate shapes, each with the same volume (assuming that the whole head is representable as one 3D volume) but with different geometry representations corresponding to the different parts of the volume that you are trying to render. So your XML file would probably look like the one at the end of this mail. Note that the geometry is loaded using custom geometry loaders since your geometry would probably not be a simple vzBlock but something more 'unstructured'. I think that you should be able to use the manipulators built into Performer to manipulate the data set. I am not sure which 'parameters' you want to modify through Performer but it seems that you simply want to be able to pick and move the various objects around?

I don't really know what the contents of a geometry file such as "jaw.gem" should be, I wonder if you have a template for such file. Also, it seems that I don't have the geometry loader library "libGeometryLoader.so", where can I get it from. Yes, you are correct, I need to use Performer/Volumizer to pick up objects (portions), move them around and possibly scale them. Your help is higly appreciated. Thanks.

Depending on your application, this might mean segmentation of the volume and then computing the approximating volumetric geometry or some other technique that is relevant to what you are trying to do. The Jaw.geom and libGeometryLoader.so are just 'hypothetical examples' that I used to explain the concept. You will need to create these files yourself to represent the geometry data and write the appropriate loaders for loading the geometry. As I said, please refer to the programming guide to see more examples of how you might go about doing that. hth, Praveen ----- Original Message ----- From: To: Sent: Sunday, May 23, 2004 12:03 AM Subject: [info-volumizer] Re: Volumizer XML > Dear Praveen > Many thanks for the reply.
