the instant alternative to hidden line

Recommended Posts

hidden line is still awful and I was thinking "there must be a better way..."

there is.  

and it's so easy I feel like a dunce that it took me 5+ years to figure it out.

1.  Have a white background and turn off grid and axes.

2. Create a white material and set the reflection to constant.

3. Turn on Antialiasing in Shaded Options

Done.  Instant Hidden Line that is at least 100,000x faster than the real hidden line and with MUCH  better results in regards to text (i didn't do a benchmark test on this, so please don't quote me).

I'm literally never using the hidden line again and i am so happy about this so i needed to share.

Very nice!  The only thing is Hidden Lines can be exported as vector.  So, there is still a use for them.

True.  I think a workaround for that is to change the image options to something high-res, export image to tiff, place this image in Illustrator, and run Image Trace. 

Depending on the model and how much tinkering needs to be done, this would probably be faster than letting hidden line grind out a rendering for 10+ minutes.

One would have to play.  Been a while, but last time I did any significant auto trace work, it was quite difficult to balance getting good corners vs smooth curves.  If I got the proper curves, then corners would always have to be manually cleaned up.    Where this was the most obvious, was on text.  Text being the technical part, may be comparable to what you would want on a CAD drawing.    That being said, Auto trace may have come a long way since then.

I use hidden line still quite a bit. It works fine for me. It's come a long way from older versions and it's much faster. Of course, if you have a very heavy scene, it will be slow, but I have yet to run into something that takes longer than 5 minutes to hidden line.

Similarly, you can place all your layers in a layer group and then be sure to select "Material" in the "Override Attributes" option. Use the white material to assign to the layer group. This method allows you to maintain the original materials while still having the option to make fake hidden line images.
