360 panorama image cube using as darts target and record the xy coordinates
Greetings. I am a GIS Analyst and would like to use the 360 panorama image cube as walls so that users of the program can create 'marks' on the 360 panorama image cube (e.g. like a darts game); in this regard I plan to record the xy coordinates of locations marked by users throwing a beach ball in a given direction.
I currently am engaging in research using Vizard software with a head mounded display device (zSight). I have been learning the relevant programming skills using tutorials and examples provided by Worldviz. However, I am not a gaming programmer and am having difficulties with specific aspects the required programming. In order to more specifically describe my difficulties, I have recreated a framework of my research environment using resources provided by Worldviz, as per the code shown below. All codes are from the 360 panorama and duck court examples. (Please note that I do not have access to more advanced software like 3ds Max, so if I need to create 3D objects then Google Sketchup is my only choice.) I am having the following three difficulties:
I very much appreciate any assistance you could provide in this regard. Thanks so much! Code:
import viz viz.setMultiSample(4) viz.fov(60) viz.go() env = viz.addEnvironmentMap('townhall_L.jpg') sky = viz.addCustomNode('skydome.dlc') sky.texture(env) NUM_BALLS = 3 BALL_SPEED = 5 viz.link( viz.Mouse , viz.addTexQuad(viz.SCREEN,texture=viz.add('crosshair.png')) ) balls = [] #Enable physics, but don't use gravity viz.phys.enable() viz.phys.setGravity([0,0,0]) #Initialize all the balls for x in range(NUM_BALLS): #Create a ball ball = viz.addChild('beachball.osgb',pos=(0,0,-40),cache=viz.CACHE_CLONE) #Enable collisions with the ball based on a sphere shape ball.collideSphere() #We want to be notified of the balls collisions ball.enable(viz.COLLIDE_NOTIFY) #Add the ball to the ball list balls.append(ball) #Create cycle for balls nextBall = viz.cycle(balls) #Shoot a ball def shootBall(): #Find the next available ball to shoot ball = nextBall.next() #Calculate the vector of the ball based on the mouse position line = viz.MainWindow.screenToWorld(viz.mouse.getPosition()) line.length = BALL_SPEED #Translate the ball to the head position ball.setPosition(line.begin) #Reset ball and set velocity ball.reset() ball.setVelocity(line.dir) #Play the gunshot sound viz.playSound('gunshot.wav') #Shoot a ball whenever left mousebutton is clicked vizact.onmousedown(viz.MOUSEBUTTON_LEFT,shootBall) #Make sure balls maintain constant velocity def UpdateVelocity(): for ball in balls: ball.setVelocity(viz.Vector(ball.getVelocity(),length=BALL_SPEED)) vizact.ontimer(0,UpdateVelocity) |

Here's an example that places markers around the panorama:
Code:
import viz import vizmat import vizshape viz.setMultiSample(4) viz.fov(60) viz.go() env = viz.addEnvironmentMap('townhall_L.jpg') sky = viz.addCustomNode('skydome.dlc') sky.texture(env) viz.link( viz.Mouse , viz.addTexQuad(viz.SCREEN,texture=viz.add('crosshair.png')) ) viz.mouse.setVisible(viz.OFF) def placeMarker(): line = viz.MainWindow.screenToWorld(viz.mouse.getPosition()) pos = vizmat.MoveAlongVector(line.begin,line.dir,40) shape = vizshape.addCircle() shape.color(viz.RED) shape.billboard() shape.setPosition(pos) #place a marker when the left mouse is pressed vizact.onmousedown(viz.MOUSEBUTTON_RIGHT,placeMarker) import vizcam vizcam.PanoramaNavigate() |

360 panorama xyz coordinate
Dear Jeff,
Thank you so much for your help!! I was so excited to receive your response for my posting, since the forum represents the only venue for me to seek help at this time. Thanks to you, the forum worked wonderfully for this purpose! This project marks the first attempt in my organization to integrate GIS functionalities into virtual reality software, and it is very challenging for me. However, I am very pleased that with the Vizard software the required application can be created with very little coding since the software provides many convenient modules. I would like to kindly ask you another question: I was able to obtain xyz coordinates and am wondering how the imported image is scaled in Vizard. For example, I use 955 x 955 images to create a 360 panorama, and Vizard then re-scales such images to 1024 x 1024 and creates an approximately 100 x 100 x 100 m environment. How does Vizard assign the scale from such images? Again, thank you so much for your help. It is very, very much appreciated. |
