I have been learning Unity for the last few weeks in order to create a simple ant simulation. The way I was rendering everything was writing to a texture the size of the camera in the Update function. It works, but problem is that it is extremely slow, getting only around 3-4 FPS doing so. What could be done to speed it up? Maybe a completely different way of rendering?

Here is the code of a simple test where some Ants just move around in random directions. I have the AntScript.cs attached to the camera with a texture under a Canvas where everything is being written to.

Given the following code:

I would like to find minimum distance of each voxel to a boundary element in a binary image in which the z voxel size is different from the xy voxel size. This is to say that a single voxel represents a 225x110x110 (zyx) nm volume.

Normally, I would do something with scipy.ndimage.morphology.distance_transform_edt (https://docs.scipy.org/doc/scipy-0.14.0/reference/generated/scipy.ndimage.morphology.distance_transform_edt.html) but this gives the assume that isotropic sizes of the voxel:

I'm trying to design a simple page for practicing with just html and css. I used a hover pseudo class for the croissant image. It works but when I hover the mouse over the croissant the coffee cup image will move to right a little(almost 50 or 100 pixels) and when I hover off of the croissant the coffee cup will back in its position before. meanwhile I'm new in web design and just start learning few days. here's my code:

So what I want the view to show is only the map of Bulgaria like shown in this picture Bulgaria map

I want the user to not be able to drag the view outside the boundaries of this picture and after zooming to be able to see the full country but again not be able to go too much outside the country. This is the code I am using for now without the limitations that I need. HTML:

I want to create a slide effect: one bitmap is painted from right to left on a form's canvas. For this I use BitBlt.

I call this function in a Timer (20ms):

The data in the controller is collected from the SQL database correctly, also it does exist in the viewData in view Cshtml.

i have an error that i just dont find a solution for. I created a little messenger thingy in flutter and have a problem when using a NetworkImage inside one of my chat bubbles.

When i send the image as message, it is displayed without problem in the bubble. Also when i send multiple images, it is no problem and they extend beyond the screen and i can just scroll up and down without any problems.

Though when i reopen the room screen and there are multiple images and they extend over the visible screen i get _CastError (type 'Null' is not a subtype of type 'List' in type cast) from network_image dart file. BUT this only happens after a hot restart. If i just navigate back and then reopen the room screen its also all fine, but as soon as i hot restarted once i always get the error when trying to open a room, which has images extending the visible space.

Iam still kinda new to flutter, so i know my code sucks mostly but this time i just dont even find a "dirty" way to solve it.

Flutter 2.2.0 (beta channel)
Dart 2.13.0 On Android Emulator Pixel 4a API 30

Edit 1: i removed a lot to make it easier to read.

Edit 2: i found it to be somehow connected to using the downloadURL from Firebase Storage. When i replace the url with just some test png url it doesnt seem to be a problem.

I have a doubt trying to understand and use glBitmap function. I started from this example and trying to draw a 40x40 "bitmap" and avoiding a situation like this I tried this:

40 x 40 is 1600 bits -> so I need 200 bytes of info (1600/8)
