points

Hi, I need to paint the line witch links two points.

I developed my own solution using the straight line equation, but my results are different than using the "professional" programs (such as GIMP or even MS Paint).

Here is a example of what I want: alt text

But my algorithm does this: alt text

*The green point is out of the figure and this is not possible.

Any ideas? Anyone know which code is been using for this, in "professional" apps?

Thanks! Daniel.

So given two points A(x1, y1, z1) and B(x2, y2, z2) that represent line segment AB, and a third point C(x3, y3, z3), what is the average distance between each point on AB to point… >>> More
