kandi X-RAY | bxh Summary
Bounding Interval Hierarchies (BIH) and Bounding Volume Hierarchies (BVH) are data structures that hierarchically divide a region of space in order to reduce the number of elements that must be considered when performing spatial queries. Space partitioning structures such as these help to dramatically speed up the processes of finding all the elements within a region or finding the intersection between a ray and a set of elements. Both B*H trees have exactly the same API and can be used interchangably. The B*H is written to be agnostic to the number of dimensions. Though the trees should function in higher dimensions they have only been tested in the traditional 2-D and 3-D layouts. All traversal algorithms are non-recursive. The tree building phase is performed using the "Surface Area Hueristic" that produces pretty good, though potentially unbalanced, trees.

QUESTION
I have 2 list with the length value of 35 in total both listA and listB. However when I merged the 2 list one of the element is gone and the length become lesser becomes 33. is there any way to make 2 list into a dict without losing any element? I tried the zip and normal for loop but still I lost something.
...ANSWER
Answered 2021-Mar-17 at 07:16listA contains two duplicated items ('Material' and 'Typ'). Dictionaries cannot have duplicated keys which explains why you are seeing less entries in your dict.
If you have duplicated keys, the best approach would be to make the value of the dictionary a list instead of a single item created as follows:
The dictionary then has 33 keys but 35 values as the entries for 'Typ' and 'Material' contain 2 items in the list.

Actually i need to get base64 image data generated by croppie javascript library. The image data look like below.
...ANSWER

only contain the files uploaded using input type="file"
. Whereas you're sending the image data as a base64 using type="hidden"
which sends data as string, not as file.
So, the image should be present in request.POST
instead of request.FILES
.

QUESTION
This is my first attempt at creating an android application. In trying to use the Awareness API provided by Google I receive a SecurityException in logcat, and the error:
"Invalid API Key for package = com.example.android.project. Status code received = 12".
Meaning, mGoogleApiClient.connect() causes the app to crash every time. Is there anyway to know what the status code means?
...ANSWER
Answered 2017-Jul-01 at 15:37Print this to the console: (new Status(403)).getStatusMessage()
. It should show status message of the error. Read more here
