Split Ouput

Post  gazzer82 on Fri Jan 03, 2014 11:15 pm

Ok, this is probably an easy one and i'm missing something.

How do i split my outputs across one canvas.

For example, say i have a Matrox THTH or Datapath X4 configured as multiple of 1024x768, how do i send an XGA output to each section of the 1 output?

In a similar theme, i often end up sending a lot of LED fixtures mapped out onto 1 1920x1080 output, in this situation i would again like to layout an output for each LED processor and "Comp" them together on 1 larger canvas output, which i guess is the same question as above?

Thanks

Gareth

the LED Config module is what you need here. the module is an alternate skin for the video out module ( insert module/display/video out ) - one added, right click the module and choose "load alternate skin"

the yellow input can be connected to either the output of a projector or from a rectangle if mapping isnt needed. the LED Config button turns the module on, the numerical screen button determines which screen video is sent to. the we are left with LED X/ Y - this is the top left starting pixel for the screen to be drawn from and LED DX / DY determines how large that screen is drawn. multiple copys of this module can address the same output at the same time, so with some sensible offsets applied to the LED X / Y, you should be able to get all the screens showing on a single output.

for the second part of the question, do you mean lighting fixtures or led screens?

Ah that makes sense, will give it a try. Having to wait for V7 RC15 to download as the 7.1 beta i have been using crashes when i try and use the LED module.

I mean LED video screen, outputting DVI, which the above solution should also work absolutely fine for!

Thanks

this tutorial might also be of use if you have a multi sectioned model for your led screen :

( im currently working on a guide to modelling and mapping complex screen shapes - hoping to get it finished today *fingers crossed* )

Will that also include the loading of obj files with a UV map?

I have an obj at the moment, but when i load it onto a default screen it seems to get flattened by Ai, let me know and i can send it across for you to look at?

Thanks

if you connect to the output of the rectangle, then it purely the texture, if you output from a projector, then its the texture applied to the 3d model.

you can send the file to arran@avolitesmedia.com and i wil be happy to take a look at it for you. ( if the file is larger then 10mb, zip it down first )

Actually looking at this again, it's because the object properties for the screen scale WxDxH where set to the default screen ones, which where not square. I assume if i set the dimensions to be real-world values the model will appear correctly in the preview window, or should i just enter square values, i.e 10x10x10 to maintain the correct aspect ratio for the model?

if the object has been correctly modelled, then leave the scale width and height both set to 1 - the value relates to the model itself rather than a default size or scale.
