This morning: uff more learning and work.
This Afternoon lets try this code ... mind blown ... thank you !
I'll mark this as solved hence I think ist a good way to close a thread with a working prototype for others to learn.
Thank You again, @zipit & @m_magalhaes

Wow ... good stuff
My c4d Programing slowed down this year, but this might be something I want to use some day ...
In my case setting this to true hides them.
customgui.SetBool(c4d.TREEVIEW_HIDE_LINES, True) # True if no lines should be drawn.
kind regards
mogh
Just additional reinforcement.
We talk here a lot of Metadata in CAD files for Digital Twins, so a universal handling of "additional" data not processed by cinema is an area to explore at Maxon !
Beginner solution:
If you do not need a certain layer you could also implement the call comand "Delete unused layers"
Its not pretty but beats any convulated self written code if it is not called to often.
c4d.CallCommand(100004760) # Remove unused layers
cheers

... while the Team probalby will ask you to provide more context / detail ... have you looked at the sdk examples ?
kind regards
EDIT:
Sorry this was not what I thought I have a dual Dialog example somewhere but not at hand ...
*This is an Subdialog Example from the SDK.
hope that is in line what you are searching.*
Cheers mogh
Here is my latest Example Code, I will check for R2023.1 on Monday.
selecting FFFF and DDDD results in GUI weirdness ... on R20
Update: Also on 2023.1 I get this UI glitch ... selecting KKKKK / LLLLLL (last ones)
Update 2: fiddled a little bit with the IDs (the class has an offset now so the ids are unique) and Layoutchange() no updated on the glitch when selecting the KKKK + X elements.

Hi ferdinand,

I am expressing myself not precise enough.
its not about the raw FPS I am worried about, 11 FPS on our vehicles is fine I guess. what keeps me up at night is these recurring stutters when moving the camera through the scene (no animation just looking at stuff)
and things like the time to see a simple cube in a empty scene - it always feels laggy or you could say delayed
or how the Live selection circle lags behind the mouse pointer (empty scene)
oversimplified example:
Heavy scene FPS graph ( 0, 0, 0, 11, 11, 11, 11, 0, 0, 11, 11, 11, 11, 0, 0, 11, 11 )
Cube creation FPS graph ( 0, 0, 0, 60, 60, 60, 60, ... )
Plugin related this is more or less what started this hunt .... :
I can interact with my Draw line Plugin (that is not the state of the plugin its evolved now but to give a exaple) on my:
the plugin performance depends on Viewport size and point number but the difference repeatable between these "test" machines.
(Cinebench 2024.1 - GPU Test 3090 ~ 17000 points 25Minutes continuous) Feels fine
cheers
Thanks Ferdinand,
the Summary only pops on "Anim Test"
Empty Scene:
my old laptop has as a live readout (~ 5ms, at 60 FPS )
my Workstation has as a live readout (~ 33ms 52 FPS )
compared to yours, mine seems off - while this will not help me immediate it keeps me sane ( I was starting to doubt myself if I really have a lag or problem ...)
thank you

I did not know about the "new" FPS helper, -> there is a checkbox "Save Profile Summary" -> where is that stored and how can I review it ?
What do all the options do exactly, is there a short explanation somewhere ? I could not find anything in the C4D Help.
thanks
Dear community,
It would be really nice if there was a SDK way to measure viewport performance. ( I guess profiling wont suffice) - Something like a plugin to measure viewport performance or something that logs frames, frames consistency, from the C4D internals.
C++ plugins are out of my expertise, and I suspect an "external" plugin wont have the access to all the measurements needed.
For plugin developers this could be useful I guess.
Where is the question ? I don't know this is probably a desperate cry for help.
Reason: I am having lag and freezes (empty scene) since S26 onwards (vague guess) and I can not get rid of them, even after several support sessions with Maxon and internal IT.
Thank you for your condolence.

Hey ferdinand,
I mixed different questions - I'll keep to the theoretical part to keep the Post relevant to the original question.
I appreciate the informative post as always. 
Parametric concept of a spline is clear to me -> that's why i asked about "C4D can not get more precise than a 0° degree line object ?" which was formulated to lose as 0° is mathematical problematic? and I know 0.1 would be better. sorry about that.
The tip about spline 'Adaptive' setting was a good hint, I never use it in work so I forgot about it.
So to summarize regarding my question.
The Line object always samples what the user has set in the spline settings and not by a unknown internal setting (for example to give good viewport performance, or nice equal sections)
And its a better fit for my application, hence there is no "linear transport" shenanigans going on.
And if I want to display a high resolution of my calculation, I make an internal copy of that spline and edit the spline settings, instead of sampling a low division spline with spline helper.
Normalization / Jagged lines:
I use Menger-Krümmung. -> will open a new topic.
Your code might come in handy when I'll extend the plugin to polygon meshes.

Remark
as humans cannot see that level of detail.
I have to disagree on this topic. As a tell tale we import CAD data here into C4D to evaluate the work of the engineers.
Not long ago I said to our surface engineer. "take a look at the end of that surface something feels off, it looks like the surface is lifting" -> The engineer reportet back "you just spoted a 0.001mm surface deviation of an unconstrained spline ending I did not set."
We could argue that the seen result was in fact not 0.001mm but perhaps to surface setup more than 1mm, (or by some rounding error C4D normal tag shading where continuous and then stagnant for 1 pixel) but my point is settings in precision are important and carry through till the final product. Even though a setting of 0.1° for a spline might might be unsuitable in most cases (rendering, performance, ...) it is not for evaluation.
So even C4D and all that rounding / conversion / floating point precision might look like unrealiable, unecessary or even esotheric it caries through to a certain degree and its more reliable than you think.
(Yes we evaluate in the original CAD Program, but the tale is that I saw something even after importing it into C4D)
As reference to why I need this:

Thank You
Thank you ferdinand,
I will implement my own "tagent" / "colinear" ending then, and not use this flag.
@ferdinand said in Usage of SplineHelp.InitSplineWith() regarding flags -> returned data:
As a warning: All the spline helpers implement parallel transport, which can make their output for curvature tasks undesirable (as it messes with what is the mathematical tangent of a spline in favour of what humans would expect. When you are at a loss about what I am talking about, search the forum for parallel transport and my username, the topic has come up multiple times in the past). It might be better to get the LineObject of a spline, i.e., its current discrete form, and do all the math based on its vertices.
Aha ... thank you - this explains why I get so different from spline-helpers tangent and cross tangent. Could also corelate to my "noisy" sampling with splinehelper (see screen below)
My question other topic but same context would be how to get a more high resolution Line-Object. We talked about this in an early stage about this, but my code wasn't mature enough to be sure. -> Is the short answer C4D can not get more precise than a 0° degree line object ?
Screenshot line object Bezier 0° degree (for enough resolution). Nice plot but resolution enough? Probably not for edge cases like flatish dips.

Splinehelper 200x samples not moving average smoothed. The noise starts to show at about double the resolution of a line object ...
Should I open another Topic?
thank you again
Dear community,
Returned Data of Flag c4d.SPLINEHELPFLAGS_CONTINUECURVE unclear.
I've read that the SplineHelp() has flag called c4d.SPLINEHELPFLAGS_CONTINUECURVE.
While the written explanation is clear to me :
Continue the curvature of an existing spline at the end points.
Its unclear to me how to utilize the data or even how the data I get is different from a "normal" helper.
Reason of interest: I am coding a "Curvature" displaying Tag Plugin atm.
thank you for your time.
cheers mogh
Hm, interesting, It works now,
either you did something or the solution is to post a comment to trigger it. Anyway Thanks.
Cheers mogh
I still have the same problem. "No push" no "unread toppics". Clearing my Browser Chache does nothing.
any idea ?
cheers mogh
I use this to Thank You Ferdinand.
This is how I imagine an SDK example should look like .... a simplest version , an altered simple version and a complex touching the boundaries of the subject.
I am thankful and praise your work .... !
