faster preview with image generation

[yannickbattail]

Is your feature request related to a problem? Please describe.
In some model preview takes a lot of time (and cpu every time the file is saved)

Describe the solution you'd like
Generate a preview image with openscad and display it instead of rendering the SLT model.

Describe alternatives you've considered
You can generate an image with openscad

openscad -q -o ./images.png -D "\$fn=10" --imgsize 512,512 --preview ./model.scad

Hello,

Thank you for your feedback. Good idea.
How would you see this feature, a toggle switch somewhere to choose between stl or image rendering ?

Not sure what is the best level to do it. What do you think would be the best :

• a global setting, that affect all the scad files of all your projects
• a project setting that affect every scad files in a project
• a setting for each file

• maybe a global setting
• or a preview by image every time the file is saved and a button for rendering the 3D model with display in the IDE
