Dear Christian,
 
I would 1st of all try to add a delay between the rotation_matrix
updates. Just guessing I would think about 100 updates per second are
enough as it is similar to the fps of the graphics window/monitor
itself. Updating more frequent is not noticeable. So a delay of about 10
ms could already solve the problem.

Dear Norman !

 

Thanks alot for the reply with a c++ Programm i open a socket and i
send it to vmd where i listen with remote_cl and the it beeing
executet,

 

i check in my Programm the Rotation and the scale Matrix from the
oculus rift, and then i send it with a socket to vmd where molinfo ..
rotaion_matrix is beiing executed. ( if i turn my head right the molekil
rotated in left so it gives me the sense of the object is still same
with Forward and backward

(Ah gerate habe ich deine E-Mail Addresse geschaut du sprichts
deutsch)

 

this works for 10 Secounds and than it stalls i dont know know whats
the reason (maybe the reason is i dont whit for the answere for each
command )

i think i have to rewrite the remote_ct . i alson dont know if the
Speed is fast enough for the oculus rift.

 

 

Danke

Hi Christian,
 
I also notice that VMD gets stalled when writing something to the
console while it’s still doing something else. Like entering a command
while vmd is still wrapping f.i. So you might want to add a delay
between your writes of the rotation matrix and see if this solves it.
 
But, actually I don’t really understand your problem description as you
say you send data to oculus rift, but seem to write data to vmd. So
could you please explain more detailed what exactly you do and how you
call your C tool?

 
Norman Geist.

Hey you all !

I made a small C Programm , sending the head coordinates (rotation
matrix and scale matrix) to the oculus rift. Well this works, i execute
.>

   molinfo top set {rotate_matrix] {{{....}}}

works yes. but after some time (1 Minute or so ) the vmd gets stalled
,seems (only seems) to me that vmd is setting to much of roation and
scale matrices so it get stalled, Am i right ( i dont hope so) or does
anybody have a better idea to send the coordniates to vmd. ???

thank you

christian
