making a pipes system

[varomix]

HI guys

I'm working on a pipes system based of a curve, the problem I have is that when a pipe changes plane, the corner joint

won't follow, here's a pic.

I oriented the normals to follow the curve but one the curve goes up, it needs and extra twist.

thanks guys

I am guessing, you are using sweep SOP, aren't you? Try stamping - gives you more accurate control over the position of the normals.

hey

well I'm actually just copying each corner joint to the points, using the curve normals

[pclaes]

you can use the cross product of the current normal and the previous normal as an up vector for the copy operation. - this does imply you don't have two point on the same line next to each other without a change of direction, as that will screw up the result of the cross product.

I added color to the cornerpieces to make it visible in which direction they are pointing.

goodluck

Why dont u use lsystem and replace line with pipe geo?

wow Peter, that works just as I need, thanks a lot I'll study it tonight.

kumpa, I didn't understand your method, can you elaborate on that please?, that might be cool also, using lsystems

thanks a lot guys
