I don't understand how to properly flatten an object in blender. In this video, the guy manages to smooth an object without reducing or curving the object. I repeat all the same steps, I get something terrible.

What I get (I smooth the object by pushing it in, is there any way to fix this?): https://i.stack.imgur.com/ddeDB.jpg
Thanks for the answer!

I have some problems with a material on a large plane.
It is a simple plane with a texture on it. When I add a simple image texture, the material looks fine. But if I then make the camera move in an animation, the material is flickering and acting wierd in the horizon. I figure that it is because the image texture is getting very small when it's far away, so it renders it a little different on each frame. I can also see that if I disconnect the displacement it stops. So it's maybe a displacement problem and not and image problem.. I don't know :) But is there a way to make this stop. Maybe a way to make it render with less detail when it's far away? Or a way to make the image texture only appear when it's close to the camera? Or something else?

I want to process the captured video. I will try to capture the video of handwriting on paper / drawing on paper. But I do not want to show the hand or pen on the paper while live streaming via p5.js.
Can this be done using machine learning?
Any idea how to implement this?
If I understand you right you want to detect where in the image the hand is a draw an overlay on this position right?
If so You can use YOLO more information to detect where the hand is.
There are some trained networks that you can download maybe they are good enough, maybe you have to train your own just for handy.
There are also some libery for yolo and JS https://github.com/ModelDepot/tfjs-yolo-tiny
You may not need to go the full ML object segmentation route.
If the paper's position and illumination are constant (or at least knowable) you could try some simple heuristic comparing the pixels in the current frame with a short history and using the most constant pixel values. There might be some lag as new parts of your drawing 'become constant' so maybe you could try some modification to the accumulation, such as if the pixel was white and is going black.
I am using blender to make a character, but every time I add a mesh cube, it won't render. I've done several attempts to make it work, but it just won't. I'm sure I'm not the only one with this problem.
If you can see it in the 3d viewer but not in the render, check in the list in the Outliner where you have all your objects and see if the little camera is clicked on.
if you can't see it in the 3d viewer but you have the point try to scale using S
With imagesegmentation I segmented objects from a webcam. But because of the bad light I get a lot of noise in the picture. I want now to improve the shape of the found objects. The only method i found is image opening and closing but the result is no as good as I wished. Does anyone know some other methods?
In this folder I have the orginal image after the segmentation, the image after closing, and a picture of what kind of picture I'm looing for.
Thanks in advance
You could try the opening-closing combination operator. This provides a better smoothing of the shapes. Further more varying the radii of opening and closing (called the ASF - alternating sequential filtering) produces smoother results.
There are a few demos online that use fourier desciptors. Its also important to choose a good shape of structuring elements, since your closing seems to close convex holes in the image.
If it is salt/pepper noise, a simple median filter may be better.
I'm completely new to ArcGIS and ArcMap, but someone suggested this program to me for a project I'm working on.
I would like to animate individual entities on a map, and was wondering if it is possible to do so in ArcMap. I asked this earlier here and a member directed me to a tutorial on animating in ArcGIS. The animation in the guide was over a map spread (ie. each pixel on the map displays, say, a different color to indicate population data in the area). However I realized that if I zoom in a lot, eventually the image will degenerate into pixels, which is why I need an actual object to mark a certain point. I checked some online tutorials and it seems like we can place markers on the map. Can someone tell me if it is possible to animate these markers (for example via a for-loop)? And if so, could you point me in a direction where to start?
Thanks in advance!
You can animate layers in ArcMap is the short answer. Its not as simple as using the timeline feature in Google Earth for example though. But then ArcMap is much more than just a visualization tool.
This help page on the ESRI web help looks like a good place to start.
I'm not 100% sure what you mean by the image degenerates into pixels. Are you saying that the markers were single points in the layer. Unlike Google Earth you are not confined to simply plotting points on the map. You can draw completely arbitrary shapes in ArcMap, which can be defined to cover actual areas of the map, so when you zoom-in the shape gets larger.
The way you need to load data into ArcMap to produce an animation isn't too simple. There might be other ways to do this, but the way I know of is to generate a NetCDF file. This file contains a 3D matrix of layer data, where each layer is separated through time. Because you generate a matrix, you are effectively placing a raster image over the map. Thus if you want to cover a large area, each matrix becomes large, and you multiply that by the number of time slices you wish to animate over.
Once you have a NetCDF file with your data in however, getting ArcMap to animate it and produce say a .avi file is pretty simple.
You could try just loading some of the example NetCDF datasets into ArcMap to see how/if they will work to get you started.
Hope that helps.
The upcoming v10 will have better time-aware capabilities, which will allow for animation.
