  1. Hi everyone, I'm trying to figure out if I can use both strings in the same project. I just need to use common function with different strings, like the following:   char* a = "raw string" wchar*  = L"unicode string"   and use the same function like   strinLength(a), stringLength(b)   I'm looking for some template functions which can handle both strings, maybe something inside the std ? I'm not sure if find, replace etc.. provided in <algorithm> can handle this problem, any idea? Because I also need to use a lot of string util functions, not just the length.   Thanks, J
  2. sphere position during collision

    Hi, thanks for the answer. I know that book, it won't help that much. I need to find the closest sphere to a triangle (or convex polygon) given the direction. I can check if the circle hit the triangles but it's not moving. I just need to move the circle as close as possible to the triangle, having the imaginary moving direction for the circle.   Thanks, T
  3. Hi everyone, I have a small problem I hope you can help me :) I have a sphere and some walls, I need to place the sphere as close as possible (so like the collision happen) to the geometry. we can think it as 2D problem:   http://upload.wikimedia.org/wikipedia/commons/6/6f/Incircle_and_Excircles.svg   Suppose my sphere is the top one (with center in Ja), I need to find that Ja vector. I have the sphere (radius, direction etc..), the geometry (can be a triangle, separate lines, no problem..). I already managed the case of hitting a line, but when I change the direction across a vertex, I get incorrect result. I mean, my problem is to get the right sphere position when I have 2 lines (concave or convex).   Thanks, Tim
