How to do screen captures in VB???

Hi erveyone

I am currently doing this reaction diffusion system, where I would like to output screencaps every 50 frames( i am using a timer). So my question is how do i do this in vb?? normally i would do it with a stored view in rhino and use the command "viewcapturetofile", but i cant seem to find this command in the SDK, if i where to propose the pseudo code then it would be like this:

(count is my timer value BTW)

if count mod 50 = 0 then

dim view as rhino.storedview = my_stored_view

dim sc as rhino.screenshot = screentshoot(view)

put in specified output folder

end if

My reaction diffusion system is working, which is why i havent attached it in this post.

Looking foreward to hear any suggestions :D

Hi Jens,

there is no direct analogy for the ViewCaptureToXXXX commands. You can tap directly into display pipelines and render to images, but it would be much easier to just script the ViewCapturetToFile command. Be sure to prepend the hyphen so you get command line control over all settings:

-_ViewCaptureToFile "C:\frame_" & i & ".bmp" Width=1000 Height=500 DrawGrid=No DrawWorldAxes=No DrawCPlaneAxes=No Enter

Hi again

Just to make sure, what you are suggesting is that I write a small macro?

I am asking because I have never done that before and I cant seem to get the hang of it at the moment(we have a little deadline pressure, so i am a little tired).

I will continue to see whether or not i can or can not figure out, because it will be very useful for the future.

Hi Jens,

I meant you should write a small script that internally writes a little macro (it would have to be a different macro each time as each image needs a unique filename). then run that macro programmatically using the RunScript function in the Rhino SDK.

I'll be happy to help you with this, but the weekly developer meeting starts in a few minutes so I'll be busy for a few hours to come.
