    Solving Linear Geometry for a 'projected intersection'

    Working on another problem here with varying results. I have three line segments in 3D and am looking to find what would be a projected intersection between two. This projected intersection is defined by a ray that is perpendicular to the axis a and passes through both segments f and s. f...

    How Can a 3D Pipe Be Unwrapped into a 2D Topology?

    I guess you could unwrap an irregular geometry. And I'd say the steps that I would take is to take z-slices along the profile, where the z plane is normal to the axis. And the axis is defined by the 'center point' (found by taking the average of the points in X-Y). But to make at any of the...

    How Can a 3D Pipe Be Unwrapped into a 2D Topology?

    Hey kyze, It is possible. The general way to go about it is to find a central axis of the pipe, assign an X,Y,Z coordinate system with Z along the length of the pipe. Then the conversion to flat is based on the radius of the point (vector from 0,0 to point) and the angle (in the form of total...

    Solving a 'skew' quadrilateral for vertex position.

    Hello chiro, thanks for the help. I worked through your reply and I think that there is one assumption that isn't true. That is: tunit x cunit = dunit tunit and cunit are perpendicular, as are tunit and dunit, but cunit and dunit are not. This means that a and c are not parallel and...

    Solving a 'skew' quadrilateral for vertex position.

    I've been scratching my head over this one. I'm trying to find a system of equations to solve for points R and S. The known parameters are: Point Q, tangent vector t and the axis vector a. The following vectors are perpendicular to each other: a,d a,b b,c c,t d,t The other known...
