Ventuz Forum

Hi all,

Pretty new to Ventuz so please bear with me. I'm really enjoying the process of creating scenes, having a .NET coding background, its been great so far. However, I'm trying to accomplish creating a presentation which uses advanced image loaders and DDS loaders to source my Textures. The file is being read from an excel cell at the moment with buttons included to switch which cell the image loader reads from and update the image accordingly. This works great in the render window in the Designer(cell content is along the lines of ventuz://images/Image.jpg). However when I go to export the presentation, firstly, all the images the excel sheet references are not included as I guess ventuz see's it as 'they have not been explicitly referenced' therefore are not required in the export. However, the Excel Spreadsheet gets exported as it holds text values used within the scene also (these appear fine in the presentation).

So my question is regarding whether or not I need to change my approach by explicitly referencing image locations (thereby Having to duplicate a lot of content within my project, as opposed to simply having one container switch which cell it reads from instead of dynamically updating it). Also with regards to when the scene is to be used.

I am also interested as to whether the presenter is the recommended way to show a scene at run time (opposed to showing the render window in full screen - or is this option used too).

and finally, as I plan to use the scene on a touch screen. Is there any way of Hiding the Mouse cursor?

Appreciate you taking the time to read this post. Any response would be much appreciated.
Cheers

Hi there

You are right, ventuz is not including the resources referenced from the excel cause it does not know about these resources. There are two ways to solve it, the first way is to use the ResourceLinker node to add resources to the export resource list. Another way is to reference the images with relative paths like "./Images/image.jpg" to point relative to the VPR file.

Cheers!

Hi Daniel,

Thanks for the swift response, thats got the stuff working now using the resource linker, so the project actually see's the content to be exported correctly. Another concern I hope you could help with is the Memory usage the scene is using, we have built a box specifically for purpose. However Our scene memory usage looks to be capped; I noticed on the scene performance says the current usage is System 1873.1/1380 GPU - 1342.2/512 Prf - 6/16ms - The system memory usage '1380' value looks to be consistent with the 32bit memory cap as outlined in this post http://www.ventuz.com/support/help/v3_0 ... mance.html; However the machine is running a 64Bit operating system with 4gb RAM, and Ventuz was installed using the 64bit installer; yet it would appear that we are still being affected by this limitation.

Any solutions/ideas would be appreciated.
Cheers

The displayed memory limit value on Ventuz x64 is a bug. It's fixed in Ventuz 4.
So you don't need to be concerned about your 1800 Mb usage on a machine with 4 GB.

Ah that's OK then. Any idea's about my Mouse Cursor query? Hiding it would be preferable as we are using it as a touch screen.
Thanks again for taking the time to respond.

You can deactivate the Mouse Pointer in the Direct3D settings of your project.
