Rectitude is a procedural editor that empowers artists to work freely, create multiple iterations and rapidly explore ideas.

In Rectitude, every action is stored in a node. These nodes are then combined into  graphs which define generators.  The values in a graph can be tweaked to refine its outcome or to create similar yet unique results. A graph can also be reused as a node in another graph to to let you build your own library of generators. 

With rectitude, you can :

  • create parametric pixel-art textures or blocks 
  • create a infinity of sprite variation. (like the spaceships)
  • create a complex scene (like a cityscape)
  • create animations, movies. ( experimental for now)

Take a look at the example projects :

Start now :

  • Build parametric pixel-art images
  • reuse them into bigger ones, up to a parametric scene?
  • export them as png, gif, mp4

You only need to learn 5 things :

  1. how to add a node to the graph,
  2. how to connect nodes,
  3. how to use the basic transform nodes : cut, move, enlarge, colorize, etc. 
  4. how to change properties of the value nodes
  5. how to export the generated image.

i just can't get this to work. it always crashes for me after i select to start a new project or open an existing project. this is the output i get in rectitude's app data folder:

io :: C:\Program Files\data\images\icon64x64.png True

io :: prj dir C:/Users/merry/rectitude projects/test

rectitude.ui.ogl.minimal_triangle :: Vertex shader compilation error: ERROR: 0:1: '' :  incorrect GLSL version: 460

any idea how i can fix this?

Hello samallman87,
Thank you for trying rectitude :) and sorry for the trouble.

This is a OpenGL Error complaining your graphic card is not compatible with the 4.6 version of OpenGL. The 4.6 version was released 5 years ago but old (or not updated) laptop or PC might not support it.
A driver update could fix it.

If it doesnt work, could you tell me what kind of machine you have ? ( More specifically what graphic card model.  )
I can investigate.

ahh, i was hoping it wasn't something like that. yes, i'm on an old machine. i'm actually using bootcamp on a 2015 macbook air which only has an integrated intel hd graphics 5000 as the gpu. is there anything i can do to get this to work or am i out of luck completely?

I am sorry but I think you are out of luck. According to wikipedia (https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units#Seventh_ge...) , this integrated model supports on up to OpenGL 4.3 on windows and 4.1 on mac. 4.3 was released 11 years ago. And the bootcamp part problably limits even more what is actually possible on that laptop.

bummer!! thank you for the info

This is incredible!

is development still being done on this application?


Yes, but the next release is quite big. so I take my time. It shouldn't be too long though. But I have no excuse for more blogpost. I'll try to fix that.

thanks for answering my question


You may want to look at : 


This is another important piece to get most of the power from rectitude.

Do you plan to release a version for Linux at some point?


Maybe. Most of the code is platform agnostic, so this is mostly a time problem.

Alright, I will keep this tool in mind then.

I, too, would love a Linux (or even OSX) version, if you ever do it.

thank you for the feedback, I'll think about it.

How should I send bug reports?

thank you for testing :)
