Made an Image Renderer

Help and Feedback Creations Feedback
#1

I made an Image Renderer system using HTTPService and the PIL Python library. It takes every existing pixel from the image given and then gets the Color3 values from it, then being inserted into roblox for coloring the canvas.

Example:

I’ve actually released this to the public, if you wanna change some code or use it for something else.

If you ever use it, have fun!

Could you make it a model, I don’t use GitHub but this would be useful.

This is really cool! Good job! :+1:

#4

Sorry, I can’t make it a model due to the GitHub page being extremely important for following how to make it work.
There’s an example place file in the GitHub page that you can check out, though.

#5

Late response, apologies for the bump but is there any way to render videos with this? I’m trying to render game intros onto a billboard but I don’t really know how to make progress on it

#6

This is old and unoptimized code, and it may lag a lot if you try to do this. I would suggest not using this, but instead using ImageLabels and ImageRectSize/Offset to render game intros.

Alright, thanks for the tip!

Actually, this brought up an idea

Instead of normal lua, you could use parallel lua which is waaay faster and that + imagelabels would massively increase performance

Hahaha just saw this. It was made in 2020?? I thought I was the first one to do this…

This is what I have so far, first I’m trying to use imagelabels to render images, later videos but it errors.

errors on “local Size = V2New(up(SizeTable)) / Division”

Error:
attempt to perform arithmetic (div) on table and number

I printed the table but that just prints “table: 0x8aa3f7abf5fb5cc2”

this is the localscript in starterplayerscripts called “ScreenBuilder” by the way

Using ImageLabels to render videos is a bad idea, unless you mean ImageRectSize/multiple images. You still should not use this code to create a canvas and render pixels.

you could integrate this to turn the bitmap (since u said PIL so im assuming asarray()) into a lua multi array. I actually had made this for my renderer. Also @asongofspace I don’t know if you already realized this but most people just put the video into a textureatlas and scan through it. Some advanced methods have come about where you use the bit32.replace() method to put the 8 bit size color texel into 32 bits of the 64 bit number. Then you just convert that to there. He hasn’t released it but it is probably what this dude who made bad apple in roblox did. Of course, you could also just do what I did and just put it into a lua array. Fact is changing the pixel color is relatively fast, what makes most of these imaging programs in roblox slow is that people try and do ray tracing with it

This code’s really outdated and I haven’t really done much with it, but very useful knowledge

#15

i want to put a different image on that but i idk which replit does it use.
