1) The goal is to draw a very large track (that will grow dinamically from zero) centered on the screen in the position and direction (rotated) of the growth. See picture please.
2) Increase the track by adding a pair of points each second (simply random in X-direction, with a fixed step in the Y-direction).
3) Zooming and panning by using touch.
4) Add a button and an item menu for switch between 3D-view and 2-D top view.
The full source code is required.
I'm the developer who will complete this template-project (with JNI and Java) with our proprietary algorithms.
The project must be done with latest ADT.
The increment in Y-direction is not fixed, this was a typo error. Both values of X and Y of new pair of points are randomly chosen (say between 10 and 20 units). The polygon must be oriented horizontally using the vector direction of latest two added points. Thus, the polygon is draw in such way that the last two points added are always centered vertical and horizontally in screen.
