Visualize your geodata in augmented reality with 3DAR by Spot Metrix. |
Feb 19th, 2011 @ 4:21 pm
See Breeze - Augmented Reality Wind Vizualizer for iPhone/iPad (via gpdawson) is almost a year old now. It has pretty smooth accelerometer and compass filtering.
One could achieve the 3D arrow effect in 3DAR by placing 4 flat planes around the user’s position like a wind tunnel with 2 opposite walls, floor and ceiling. Rotate the wind tunnel to face the wind direction. Animate the arrows by changing texture map coordinates.
Use sphere.obj to draw a wireframe sphere. I’d use 2D RoundedLabelMarkerViews for the compass directions since 3DAR doesn’t have an OpenGL text facility yet.
