Create IsoCam

Create Isocam creates an orthographic camera with which you can render isometric views. You can choose between three camera setups.

  • A camera setup for true mathematical isometric

  • A camera setup with a view that is needed to render traditional isometric graphics for a 2D game with a ratio of 2 to 1

  • A camera setup to render a special game iso format with a ratio of 4 to 3

I host this script at my server. But my server goes down for a few days now. So i attach the script directly here.

# This script creates two kinds of isometric cameras. 
#The one, TrueIsocam called camera, is the mathematical correct isometric camera with the 54.736 rotation to get the 30 degrees angles at the sides of the rhombus. 
#The other, GameIsocam called camera, is a camera with which you can render isometric tiles for a 2d game. Here we need a 60 degrees angle instedad of the 54.736 one to get a proper stairs effect and a ratio of 2:1
# Then there is the special case with a 4:3 ratio, which is button 3. You can also make 2D games with that one. The view is more topdown though as with a 2:1 ratio of the traditional game iso view.
# The fourth button creates a simple groundplane where you can place your stuff at.

#You can of course set up everything by hand. This script is a convenient solution so that you don't have to setup it again and again.

I’ll have to try this out. Thanks!

just wondering
would it be possible to add the 2 other type
dimetric and trimetric projection
and may be other projections type

nice work
thanks for sharing
happy bl

Hi,

Will this be updated for Blender 2.8?

Thanks!

Yes, please update. This script is essential to my project. Thank you very much.

Hi. Thank you for porting this to 2.8. regards

For those wondering how to run the script, open Blender 2.8 -> Scripting -> Text -> New Text -> paste the code

Thanks dude!!

Thank you so much!

do you think you can add other type of

it would be very interesting as options

thanks
happy bl

Can anyone make it for the new update?

For those wondering how to run the script. Download the .py file and install it as an add-on (Edit -> Preferences -> Add-on -> Install). Don’t run it in the scripting mode…

Cant acces the link,can you make a new ?

Hi, it seems that in 2.92 the Shift+A is not there, the panel is ok though.

Is it possible I am doing something wrong?

No, it is not there.

is this discontinued? ive been looking and nothing really seems to work with 2.93

I will try to port it to latest version.

Works in Blender 2.93, 3.0
