Camera not moving correctlly in 3d space

Asked 2022-Feb-27 at 05:30

I am currently working on moving a camera in 3d space. I want it to move ONLY in the x and z-axis (horizontal). So far it was moving correctly when the rotation of the camera is all zero, but when I change the value of it, the camera starts to act a little weird, moving in the wrong direction. I am using SFML, but I think it's the math that causes the problem. It is weird because the code I move the camera is identical to one of the projects I wrote earlier, but the project works fine.
Here's the code that constrains the rotation:

After digging into my code for a long time, i find that the problem is in the code where I constrains my rotations, and how I get the "trans" matrix.
First, the constrains code should be:

Update 2/14: Seems like skeletonization only took you part of the way there. Here's a better solution which I believe should get you the rest of the way. Here's how you would do it in scikit-image - maybe you can find the analog in OpenCV - seems like cv2.findContours would be a good start.

QUESTION

Apply Caman JS preset filters to Konva React

Asked 2020-Aug-12 at 19:29

By creating a ref for the layer component I am able to access the canvas element which I could then pass to the caman function to apply a preset filter to the image in the canvas. This works as expected however, when saving the stage as an image the filter is not applied. How can I export the Konva stage as an image with the Caman filter applied.

According to https://konvajs.org/docs/sandbox/Native_Context_Access.html, it is not recommended to manually change canvas content (by Caman manipulation in your case).

If you want to apply Caman you can:

Cache node and write your own custom filter https://konvajs.org/docs/filters/Custom_Filter.html. To make it work with Caman you can convert imageData that is used in Konva filters into canvas, then apply Caman filter, then convert back to imageData
Or if you want to apply filter just once (on export) you can convert a node into element first with node.toCanvas() method. Then use resulted canvas in Caman.

QUESTION

Blank screen when generating point cloud from image with Open3D

Asked 2020-Mar-27 at 15:38

So I tried creating a point cloud with the Open3D library in python and in the end, it's basically just the 2 lines as referenced in here, but when I run my code (see below) all I get is a white screen popping up. I've ran it in Jupyter notebook, but running it in a python script from console didn't change anything nor it threw an error. I should mention that I created the images in Blender and saved it as OpenExr, meaning that the depth value range between 0 and 4 (I've truncated it to 4 for the background). You can see that they are proper images below and I could also transform them to Open3D pictures and display them without problems.

Edit (27-03-2020): Added complete minimal example

In short, Open3D expects your 3-channel color image to be of uint8 type.

Otherwise, it would return an empty point cloud, resulting in the blank window you see.

Update 2020-3-27, late night in my time zone:)

Now that you have provided your code, let's dive in!

From your function names, I guess you are using Open3D 0.7.0 or something like that. The code I provided is in 0.9.0. Some function names changed and new functionality added in.

When I run your code in 0.9.0 (after some minor modifications of course), there's a RuntimeError:

QUESTION

Using preg_replace with varying variable replacements

Asked 2020-Feb-10 at 11:41

I'm trying to use preg_replace to search for a string but only replace a portion of the string, rather than the entire string, in a dynamic fashion.

For example, I am able to find the strings 'od', ':od', 'od:', '#od', and 'od ' with my code below. I want to replace only the 'od' portion with the word 'odometer' and leave the colon, hashtag, and white spaces untouched. However, the way that my current preg_replace is written would replace the colons and the hashtag in addition to the letters themselves. Any creative solutions to replace the characters only but preserve the surrounding symbols?

Thank you!

ANSWER

Answered 2020-Feb-10 at 11:41

You can add capture groups around the characters before and after the matched abbreviation, and then add the group references to the replacement string:
