3D Distance Formula
Hey,
I know this sounds stupid, and it''s a simple formula, but for some reason I can''t remember it right now. I figured a quick answer might come from this forum. What is the 3D distance formula? I know I''ve used it many times in the past, but it escapes me at this time. Thanks ahead of time!

Thanks, but what do the [ and ] represent?

List it as you would in c++ for two points. That would be a good example for me.

the [ and ] were just meant as parenthesises (sp?), written differently than the standard ( and ) simply to clarify where each sub-expression begins and ends.
It''s the standard pythagorean theorem for 3 dimensions.
in C/C++
It''s the standard pythagorean theorem for 3 dimensions.
in C/C++
float dx = x2 - x1; // delta xfloat dy = y2 - y1; // delta yfloat dz = z2 - z1; // delta zfloat distance = sqrt(dx*dx + dy*dy + dz*dz);
Thanks a million!

Yeah, I remember someone was writing an equation and used the [], it was a bit confusing until I realized math people wouldn''t put up with (( in their equations. It is a bit hard to read, especially on really long equations. I usually break down my equations into multiple lines, it helps if I decide to rewrite in asm later.
