ive run into a problem which ive hopefully understood…
my patch takes video textures and applys them to an xfile to allow me to do 3d mapping with a pointeditor to adjust the vertices. it works great on one screen but freezes when i try and use the 2nd monitor output.
if i understand correctly its because of a directx issue ( dx only renders to one device? ) which needs spanmode to get round it. as im a win 7 user, i dont have spanmode ( doh ) but i spotted a spanmode plugin in v4.
so before i loose myself in trying to get it working, my questions ( finaly ) are
is the spanmode module what i want?
if i use the spanmode module, can i make it so one monitor has the graphics output whilst my laptop has a gui ( which i see can be made in v4 )
maybe there is another way round this?
if it helps to know - im on win 7 with a Geforce 9600m gs graphics card.
Yup, vvvv’s biggest flaw (please joreg!) is you can’t use a fullscreen renderer on a dual view setup. The spanmode module only works on spanned desktop.
Do you need video on both heads? 2 renderers 1 has the mesh with video texture, the other mesh without texture.
Alternately you can drag a window to fill the screen and ctrl+8 to hide the border, but performance is reduced compared to fullscreen.
dx renders on multiple devices and so does vvvv. only vvvvs VideoTexture (EX9.Texture) can only render to one dx-device at a time.
there are 2 graphic-card settings: spanmode (not available on vista/win7):
*one dx-device for multiple outputs on one graphic-card
*a fullscreen renderer stretches over the whole desktop
dualview
*multiple dx-devices for mulitple outputs on one graphic-card
*renderers go fullscreen on individual outputs independently
(multiple graphic-cards require multiple dx-devices anyway.)
the spanmode module only helps if the graphic-cards driver is set to spanmode.
so please note, this is not a joreg/vvvv flaw but a win7/graphic-cards driver problem. concerning the videotexture-issue i have promised to keep stumm.
