I haven’t tried your example, but my experience is different than yours. I recently wrote a script which divides up a compute intensive job and laun…

When working with splines in Maxscript, there are two different concepts or notions of distance/position/length. There is vertex based, and arc-leng…

You’re getting hung up on something. The function I just posted returns the position of B3. It is literally exactly what you asked for in your first …

From this page: Geometrical calculations : points, lines, planes : intersections, distances, angles 3ds Max SDK and MaxScript …

His code is for 2d intersection. The page I linked to has 3d intersection. To calculate which line needs to be extended, you could test to see what l…

Yes. That is why you need the formula from the page I linked to, or the one Denis posted. It calculates the position of b3 based on the inputs a1 a2 b…

The distance you need to move a2 is the distance from a2 to b3(intersection), yes? Or length b3-a2. In reality, you probably also need to determine t…

To make the line intersect, move one of the lines endpoints to the point of intersection. In your illustration, you would set the position of A2 to be…

There are a lot of useful calculations here, including line intersections: Geometrical calculations : points, lines, planes : inte…

PhilippeG: Hello folks, Today 2021.1 releases with more fixes and tweaks to raycasting. I fixed the remaining known issues with raycasting in term…

Look forward to the fix. Thanks for looking into it.

Not sure if this is related since it’s a different function call, but the timeline is consistent with changes made for Max 2017 so it doesn’t seem lik…

This is some fantastic innovation. Figures it was done outside Autodesk.

So I was able to answer my own question. Here is what worked: at time t rot_out_z = cam_copy.rotation.controller.z_rotation
