texture issue rendering 2 different screens

September 13, 2006 | 3:29 pm

Hello,

I’ve come across a problem which I don’t quite understand :
I’m :
-rendering a plane in jit.gl.sketch
-the plane is textured by a jit.gl.sketch
-this result is captured for use as a texture, using the @capture
‘name’ method.
-a second jit.gl.sketch uses that resulting texture
-this result is output so screen 1.

a second construction like that, using a second jit.gl.render, does
the same thing, renders to a second window which is output to the
second screen connected to the PC.

now, what happens : on the main screen everything renders fine, on
the ‘extended’ screen, all is blank. When dragging a window across,
it shows the content on the first, and ‘blinks to nothing’ as soon as
the windowposition crosses the border to the second screen.

Is there something that should be taken into account when rendering 2
contexts, with textures, with jit.gl.texture and/or @capture? Or any
known issues?

system : max 4.5.7, latest jitter for XP
pentium D, core duo 3.something
nvidia 7950

cheers,

Brecht

I should maybe ad that the failing of rendering on the second screen
is only the case when I use a jit.gl.texture with the same name as
given as an argument to the @capture attribute.
If I just give the 2nd jit.gl.sketch the message "texture ‘name’" it
works fine, but then the texture is not as nicely wrapped on the
geometry as when I use jit.gl.texture.
I’ll see if I can make a stripped version as an example patch and
post it lateron.
