Working with iPhone and Objective C. I am working on a game and I need to correctly reflect a ball off a circle object. I am trying to do it as a line and circle intersection. I have my ball position
Do either of the below approaches use the correct mathematics for rotating a point?If so, which one is correct?
I\'d like to have a straight forward C# function to get a closest point (from a point P) to a line-segment, AB. An abstract function may look like this. I\'ve search through SO but not found a usable
What R packages are available to calculate the minimum bounding box for a great circle? For example: box <- polycirc( c( longitude, latitude ), distance=35 )
I\'m raytracing and would like to speed it up via some acceleration structure (kd-tree, BVH, whatever). I don\'t want to code it up myself. What I\'ve tried so far:
I need to draw a polyline into a DrawingVisual. I\'m using StreamGeometry for performance reasons. The problem I have is that I can\'t figure out how to enable anti-aliasing. I can\'t find any method
There\'s a line A-B and C at the center between A and B. It forms a circle as in the figure. If we a开发者_开发问答ssume A-B line as a diameter of the circle and then C is it\'s center. My problem is
I have the lat/lon of 2 points on the earth. They are really close together, <10m. Let\'s assume the earth is flat. How do I calculate the distance between them in metres?
I have to be able to set a random location for a waypoint for a flight sim. The maths challenge is straightforward:
I am currently designing an RTS Game in XNA. So far I have a Terrain Model generated from a Heigthmap and some Units that are drawn on it.
