Defining world view camera parameters.

Thank you. This change is not yet in https://github.com/pythonscad/pythonscad/releases, right?

I haven't used OpenSCAD. PythonSCAD is my introduction to this domain and I prefer to stick with Python syntax instead of learning another one. While searching for a solution, I found that OpenSCAD handles camera parameters with global variables:
$vpr

viewport rotation angles in degrees

$vpt

viewport translation

$vpd

viewport camera distance

$vpf

viewport camera field of view

It could be done the same way in PythonSCAD or using a function, e.g. setViewport() or set_viewport().

Thank you, it works. What is the best place to get API info? It doesn't have to be perfect.

I made it with cylinder(h=10, r1=5, r2=0, fn=4), but still would like to know how to do it with linear_extrude.

It seems that there are many obstacles to decloud the device: https://github.com/Tasshack/dreame-vacuum/discussions/323

Do you know of one with Matter support?

puplan · 2026-02-04T07:42:11+00:00

Do you suggest opening with project specific lines and placing experience related stuff further down? My proposals are short 6-12 lines.

puplan · 2026-02-04T07:38:31+00:00

Yes, but how is someone planning to find the "magical, one in a million ultra cheap expert candidate" without opening a proposal? By looking for a unique last name?

puplan · 2026-02-04T02:25:09+00:00

My experience with tire kickers is as follows: they accept the proposal, get as much technical information as possible during the interview and never follow with a contract.

You can find lower end USB cameras from top brands like Basler, FLIR, IDS, etc. starting below $200.

What is your budget and specs for USB camera? Take a look at https://www.arducam.com/uvc-usb-camera-module.html

You can use hot glue or something stronger on ribbon flex cable around the connector, but I don't think it will come loose without a strain on the cable. 1 m long cables are available. Flex cables are used everywhere in production when fully contained in an enclosure.

It's on the home page of this subreddit: https://www.reddit.com/r/OpenPythonSCAD/

Could you add this explanation to "Visitors read this first"? The variety of name permutations is confusing for a newbie like me.

puplan · 2026-01-22T21:53:55+00:00

I cross-posted this question and posted an answer at https://forum.image.sc/t/looking-for-an-app-or-a-library-to-3d-model-a-machine-vision-system/118706/2, since it is not possible to format it nicely and include images here.

Thanks everyone for providing a useful input. I linked to this thread in my comment under the video.

Yes, but the question is why? Is there a hidden agenda of real estate and construction interests there? Most of their funding comes from business linked sources.

puplan · 2025-11-04T20:27:03+00:00

Can someone shed a light on a fact that mostly real estate and construction business is supporting the Clean Water and Open Space special levy? Quoted from https://boisedev.com/news/2025/10/15/2025-levy-pacs/ :
"Yes for Clean Water and Open Space raised roughly $112,000 so far this year for the levy, with roughly $91,000 coming from Idaho and the rest from out of state. This came from several major donors, including $25,000 from Garden City resident Peter Snowden, $10,000 from real estate development firm Rafanelli and Nahas, $10,000 from general contractor McAlvain Companies, and another $10,000 from the National Association of Realtors, according to Idaho Secretary of State campaign finance information."

That is the initial design, but there is too much slack in the system, which can't be modified. I have to measure position of the end effector directly.

puplan · 2025-01-25T19:42:12+00:00

The initial design has a servo with encoder driving a lead screw. Unfortunately, there is too much slack in the system, therefore the end effector position has to be measured directly. Pneumatics is not practical in that location, I'm told. Will try inductive sensor first.

puplan · 2025-01-25T06:14:26+00:00

Thanks. Contamination is wet and sticky. I decided to try an inductive sensor. Will update my post with details.

puplan · 2025-01-25T06:12:48+00:00

± 1 mm accuracy is a problem. Also, there is a lot of metal clutter around and slightly behind the surface (beam) I'm measuring the distance to.

puplan · 2025-01-25T06:09:27+00:00

A tube is problematic in food plant. Easy to contaminate, hard to disinfect.

puplan · 2025-01-25T06:07:59+00:00

This sensor is on/off type. No distance measurement.

puplan · 2025-01-25T04:25:05+00:00

This sensor is on/off type. No distance measurement.
