This is because volview uses Multipipe SDK (MPK) and MPK is only shipped for IRIX and 64-bit Linux (for the new SGI Prism systems). On 32-bit Linux, only the binaries for volview are shipped and can be found under /usr/demos/Volumizer2/bin. hth, Praveen PS. I looked up the info-volumizer subscribers and your name does appear. I am curious as to why you do not receive messages send to the list. If the problem persists, please let me know. ----- Original Message ----- From: "Yanhong Li" To: Sent: Saturday, November 06, 2004 2:18 AM Subject: [info-volumizer] sample code for volview > > Hi, > > I downloaded Volumizer2.7 evaluation version for > linux.

Let me try to answer this one for you. The formal SGI policy on transferring software licenses is as follows: SGI will allow transfer of a key for the same version of software from one system to another with the same OS if the following conditions are met: 1. The customer has an active software support contract for that specific application. 2. Both systems are owned by the same legal entity. 3. The application being transferred has not expired or been divested. In order to make this happen, all you need to do is call your SGI support number and request the transfer. They will ask you for all the pertinent information to complete the request. If you do not have a valid support contract, you can call your sales representative and purchase one and then begin the transfer process.

Hence once you have passed the volume data to Volumizer, you can render RGB data sets in the same way as LUMINANCE or RGBA datasets. However, it is important to note that RGB data sets do not have any transparency associated with them. The rendered image might not necessarily be what you would expect with typical LUMINANCE or RGBA data sets. So, if you need alpha, depending on your graphics hardware, your best bet might be to try and use a shader which introduces alpha in the final rendered image (using a fragment program, for example). If you don't care about alpha, you should be just fine using the default rendering pipeline. hth, Praveen ----- Original Message ----- From: "Abhijit Lothe" To: "volumizer mailing list" Sent: Friday, November 19, 2004 3:12 AM Subject: [info-volumizer] use of color images > Hello praveen, > i would like to confirm if volumizer can directly display the RGB > volume avaible in the form of 2D RGB slices since the manual hasnt > given any example for RGB. it would be really helpful for new comers > like me if you could include one RGB volume example in the manual. > > Thanks > > -Abhijit From info-volumizer-owner@els.sgi.com Sat Nov 20 00:47:35 2004 Received: (from majordom@localhost) by els.sgi.com (8.12.10/8.12.2/els-2.2) id iAK8k3Y24295354; Sat, 20 Nov 2004 00:46:03 -0800 (PST) Received: from rproxy.gmail.com (rproxy.gmail.com [64.233.170.202]) by els.sgi.com (8.12.10/8.12.2/els-2.2) with ESMTP id iAK89lva4233876 for ; Sat, 20 Nov 2004 00:09:48 -0800 (PST) Received: by rproxy.gmail.com with SMTP id g11so259821rne for ; Sat, 20 Nov 2004 00:09:46 -0800 (PST) DomainKey-Signature: a=rsa-sha1; q=dns; c=nofws; s=beta; d=gmail.com; h=received:message-id:date:from:reply-to:to:subject:in-reply-to:mime-version:content-type:content-transfer-encoding:references; b=uroBy+CnGzNtAMMBDGUJjcIbxXz6X2mHJgvQ9LUklPypPkekxGqXCOldkY6eXWv7jLeZU/2g7aMr82BPRB+kQpjdfQ8bklZivNvVrWUbhpUAfZ9+IK+oGiC/3vLfKCuehmL3WBkx8p9dum3tz5H6disJ7+2VSgWEQDJ3NDXbfsA= Received: by 10.38.181.38 with SMTP id d38mr72179rnf; Sat, 20 Nov 2004 00:09:46 -0800 (PST) Received: by 10.38.162.23 with HTTP; Sat, 20 Nov 2004 00:09:46 -0800 (PST) Message-ID: Date: Sat, 20 Nov 2004 03:09:46 -0500 From: Abhijit Lothe To: info-volumizer@els.sgi.com Subject: Re: [info-volumizer] use of color images In-Reply-To: <003901c4cdc4$d4818a80$5e5a0e86@praveenlaptop> Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit References: <003901c4cdc4$d4818a80$5e5a0e86@praveenlaptop> Sender: owner-info-volumizer@els.sgi.com Precedence: bulk Reply-To: info-volumizer@els.sgi.com Thanks Praveen. I am facing a problem using the RGB data. I am creating vzParameterVolumeTexture object with an RGB data. The data was created by reading 49 2-D TIFF images each of size 1024 X 1768 . They have 3 samples per pixel with 8 bits per sample. I passed VZ_UNSIGNED_BYTE as the texture type and VZ_RGB as the external type. My data is stored as a 1-D array of unsigned char with dimensions 1024 X 1768 X 3. I used simple TM renderer and simple TM shader to display the volume. But it gives runtime error and program does not run. I am running it on windows platform (XP). I was not able to figure out the error since it seems to be coming from the draw function of vzTMRenderAction. Could you please help me in this matter. Thanks .

I assume that you mean 1024 X 1768 x 49 with 3 bytes each? The run-time error could be any number of reasons. Please try the following - - Test your app with a smaller RGB data set (say 256 x 256 x 256) to rule out the use of RGB data as the cause of the error. - Make sure that system has enough memory for the data set to fit. - Look for errors reported by Volumizer. If there is an internal error inside Volumizer, it calls the vzError::error() method, which prints an error string to the console and calls abort. Run your app from a console, and look at the error message for the source of the error. - Volumizer uses an environment variable VOLUMIZER_DEBUG_LEVEL to print out debug messages to the console. The higher the value, more the debug messages printed. That is another useful source of information for possible cause of the error. Of course, if the error or debug messages don't make any sense, you can send them our way and we will try to take a look :) If you do so, please also send more information about the system configuration, like memory size, graphics card and driver version, etc. Cheers, Praveen ----- Original Message ----- From: "Abhijit Lothe" To: Sent: Saturday, November 20, 2004 1:39 PM Subject: Re: [info-volumizer] use of color images > Thanks Praveen. > I am facing a problem using the RGB data.

Can you please give me the system info and debug messages output by Volumizer? We will try and test this out on our end and make sure that it is not a Volumizer bug or if it a bug with the graphics driver vendor, we can workaround that inside Volumizer. Theoretically, if you have enough main memory on the system, you _should_ be able to load and render _any sized_ volume data at the original resolution with Volumizer (the performance, of course, would be determined by various factors such as graphics memory size, bus speed, etc). - Praveen ----- Original Message ----- From: "Abhijit Lothe" To: Sent: Sunday, November 21, 2004 11:26 PM Subject: Re: [info-volumizer] use of color images > Thanks Praveen, > It worked after reducing the size of the dataset.

You don't seem to be allocating enough memory for the volume data. The size should be - 32 * 32 * 32 * 2 * sizeof(unsigned char); 2. It is not a good idea in general to pass locally declared arrays to the vzParameterVolumeTexture class as the data ptr (or to any other class in Volumizer which requires you to pass a data pointer). Chances are, that once your code reaches the renderAction->draw(), this memory has already been free'd! - Praveen ----- Original Message ----- From: "Yanhong Li" To: Sent: Tuesday, November 23, 2004 7:16 AM Subject: Re: [info-volumizer] use of color images > > I have the same problem.

Could you please suggest some graphics card and memory size of the RAM that we need to have to be able to display the Visible Human Colored Dataset (9GB) in the absence of the clip loader for Windows machine?. The data is 1760 x 1024 X 1800 RGB with 1 byte per sample. I would also like to know if some parallel processing can be incorporated at any stage. The system information for the machines is as follows: Machine 1 (Windows Desktop): 64 MB ATI Radeon 8700 1GB RAM, P4 2.1GHz Machine 2 (Laptop): 32 MB Nvidia GeForce FX 5200 512 RAM , Pentium M 1.5 GHz I ran the same program on both the machines. Both machines gave an error. The complete trace is as follows. Please not that i have tried to render only 100 out of a total of 1800 slices. The follwoing error is on the Machine 2 but machine 1 also gives similar error.
