Question Turn using keyboard when using Oculus

Hi guys,

I cannot figure out how to get the viewpoint to turn using a key binding. I can obviously turn my head in the oculus rift, but this is not practical for the application. I need to be able to turn using a key on the keyboard (or controller). Is this possible? I'm using the sample Oculus code that came with Vizard.

Any help much appreciated,

Seadna.

I think there is a demo using keyboard to control a BMW car, and that one should work

have a look at "vizconnect" section in particular input, tracker and transport section. I think from memory you want to tie a keyboard input to the driving transport or maybe even pivot depends if you want to move around scene or just rotate.

Could you provide an example code snippet of how this would be done? I'm new to python and currently learning it through using Vizard.

Take a look at the 'Oculus Desktop Configuration' option in the vizconnect presets page. That adds a transport controlled by keyboard input signals.

Great I think i have found what I need. Now i need to figure out how to fit it into what i have already coded.

Thank you Jeff.

Question

OK I'm struggling with getting this into my code:

Code:
# Setup arrow key navigation
MOVE_SPEED = 2.0
def UpdateView():
                yaw,pitch,roll = viewLink.getEuler()
                m = viz.Matrix.euler(yaw,0,0)
                dm = viz.getFrameElapsed() * MOVE_SPEED
                if viz.key.isDown(KEYS['forward']):
                                m.preTrans([0,0,dm])
                if viz.key.isDown(KEYS['back']):
                                m.preTrans([0,0,-dm])
                if viz.key.isDown(KEYS['left']):
                                m.preTrans([-dm,0,0])
                if viz.key.isDown(KEYS['right']):
                                m.preTrans([dm,0,0])
                if viz.key.isDown(KEYS['up']):
                                m.preTrans([0,dm,0])
                if viz.key.isDown(KEYS['down']):
                                m.preTrans([0,-dm,0])
                if viz.key.isDown(KEYS['lt']):
                                m.turnLeft                           
                if viz.key.isDown(KEYS['rt']):
                                m.turnRight                            
                navigationNode.setPosition(m.getPosition(), viz.REL_PARENT)

vizact.ontimer(0,UpdateView)
You can see the lines I have put in with m.turnLeft and m.turnRight. These do not work like in the vizconnect example. I'm sure i need to add much more code or replace what I have here but there is so much in there that i dont know what to do with it.

I tried putting in m.preEuler(0,dm,0) and adding navigationMode.setEuler(m.getEuler(), viz.REL_PARENT) but that causes the view to rapidly spin constantly.

Is there a reason you're trying to do this in your own script rather than use vizconnect?

I hadn't used visconnect until you mentioned it here and I already have a lot of script put together. I'm not sure how to integrate my script with the mass of script that visconnect created or how to take the script I need from visconnect to integrate with my own.

Its seems like it should be much easier than this but then I'm quite new to this so i don't really know. I have learned everything so far from looking at the demos and samples and the help file that came with Vizard, but i can't find out how to do this.

Any help would be much appreciated!

Take a look at the vizconnect tutorials. These will explain how to use the vizconnect config file in your own script.
