My problem is what i can draw itinerary between multi-points in openlayers 2.i have more than 2 points.
how i can draw the path of car in map with openlayers2.

I am rendering a 3D Obj model in iOS. http://metalbyexample.com/picking-hit-testing/. I am following the above Tutorial written by WM to find the hit point in the 3D model. Using the above link I can find the intersecting point with 3D model. I want to find the triangular polygon where I touched and I want to find the UV coordinates in the Image texture. How can I do that..
I have two cordinates and radius values, using that i am drawing two circle on mapview. Now i have to find the two intersection coordinates, where two circle cross each other. same image shown below:
How can I do that?
The blue dot and the blue area will need to be able to collide and to do so I need to calculate a path to create the physics body from.
I need help figuring out how I would create the path for the darker blue ring area (the darker portion of the ring within the light blue highlight).
I know it would have two arcs and two lines, but I need to be able to calculate the path based on the distance from the center and the angle (so in the image for example the angle would be 45 degrees, or PI/4, radius 1 would be 180px and radius 2 (the smaller one) would be 165px.
How would I create a dynamic path like this?
Suppose one image like circle image is there. Then I want draw circle over that image, then check two image is same or not in iOS. I tried image matching using CGPoint, but for circle and triangle what to do.
For matching two triangles you may have two choices:
define two areas in each traingle, then calculate areas ratio, they must have the same ratio if they are matched
try to detect three points of each triangle, then calculate the barycentre coordinates
they are invarinat
For circle, if you could easily to represent each circle by a triangle which its points cross that circle, you can find the invariance by the previous steps.
How do I draw a straight-line between 2 points in BlackBerry maps? I've found how to draw a route between 2 points. I want draw a line like in the following picture, where 4 points are used.
