Soft Shadows

that's because I added sky and ground, I thought it looked better

Here are the Sketchy Shadows with you tileable mask.

Thanks for the help with this. Hopefully we will get the Beta Test version of NprTools out soon so that you and others can try this yourself.

Al Hart

BTM - If you get a chance send me two tileable sketches for Criss Cross (a separate for image for left to right, and for right to left). I am working on a concept where I will use the only the first image for the light parts of the shadows, and combine both images for the dark parts of the shadows. It would be great if I could have some good images to use for this.

The first image will go from light to dark in the 1st 1/2 of shadow intensity, and then the first image will stay dark as the second image goes from light to dark as the shadow intensity goes from 50% to 100%. (If that makes any sense. If not, send me the images and I can show you)

Al Hart

Your images are awfully similar - but that may be all right (You would be a better judge of that then me)

Don't worry about quality - we can improve that after we see if the idea works.
(I am planning to offer you a free copy of NprTools in exchange for 6 to 10 images which I can include in it. Not a great deal for you because I don't think we will charge much for NprTools. I have already offered free copies to everyone who has helped with it - and that just about equal the number of people who might be interested in it when it is done.)

I suspect that the individual lines may be too thick. You should paste the two images on top of each other to make sure you are happy the effect the cross hatch will have.

(This isn't quite right - because I simple pasted them together rather than blending them together.)
Here is a sample from another web site.

I don't really like their result, but it reminds me that I may want too allow 3 or 4 layers instead of just 2.

I am trying to achieve an effect something like this.

BTM

Ah, don't worry, I think I know what you mean.
First set just made Tile-able with GIMP, second was edited to match up better in the texture.
_First set:

_Edited set:

All images were done with a 6B pencil.

The tiled images aren't that big, so they might not look too good. I can redo them in a few minutes though.

BTM

Hmm... My post was a bit messed up. you were right about them being similar, I just flipped them vertically, and the latter (better) 2 images are messed up, and are showing the same one
i'll try to make some thinner lines (more detailed too). Might get them up soon, or have to wait 'till tomorrow.

And you need to stop editing your posts after I have already started my reply.

Al Hart

Thanks - I'll give them a try - but it may take a day or two...

, again.
... Newer cross-hatching textures
Oh, and i don't know how well these will work, but I made tile-able thinner lines.
1st
2nd
3rd
4th
This is slt3 turned on it's side, which could be the 5th layer if you wanted to go that far.
Don't pay attention to the file names, they aren't in any order at all
This is what sketchup looks like if they're all set as tiled masks at once, with black background and white fog.

BTM

... Tomorrow I'll probably make another set, more of a straight-thin-pencil style though.

Al Hart

Thanks for the pattern, BTM. I got the criss-cross shadows to work - the first pattern is used for the lighter parts of the shadow, and the second pattern is brought in for the darker parts (and overlayed over the first pattern).

Also, I made these shadows red (someone had requested colored shadows, so I added a shadow color button) (I can't see that they are red. (Someone just told me that this model didn't look very good. Pay attention to the technology of the shadows, not the model or the final result. If someone has a small model which would be better for these examples, sent it to me.)

I like it a lot on the house shadow that is cast on the ground. Any chance of seeing it with a regular grey shadow instead of the red? Its really looking great Al!

Good to hear from you again - this whole "soft shadow" think came from your idea of taking several (64 or so) images moving the sun around, and combining them to get softer shadows. As a result you will get a free copy of NprTools when it is delivered.

Send me a model you would like to see some soft shadows on, and I will run it through as a test case.

Chris Fullmer

Oh I've been eagerly watching this thread Al. I think the soft shadows are coming along very well. I genereally prefer them with no hatching, but the criss-cross pattern on the last one is actually quite nice I think. I think it has to do with the density of the strokes. They are closer and tighter in that example than they have been in some of the others. I like that best.

Anyhow, its coming along really well. I'll find a model and PM it to you. Keep it up!

Chris

Al Hart

Thanks,

I'd like to try another model.

I'm getting tired of looking at this one.

There are a lot of settings here for density, color, transparency, pattern, blurring, etc. which you will be able to use when I get the Beta out.

BTM

Soft shadows could probably be good for indoor scenes (windows). Maybe you should make some indoor scenes, as well as outdoors.

Pixero

Wow, I'm really looking forward to this.
And colored shadows, yeees!

Question, does the line scale factor also go into less than 1 for getting even thinner lines?

Al Hart

Here is an interior scene:

Here is the result with soft shadows (no cross hatch)

Here is a result with cross-hatch. I don't think it worked well. I might try a light (rather than dark) hatch in the sunny area instead.

Here is a BW image with cross hatch.

The scale factor can be less than 1.

It scales the entire pattern, line and spaces between lines - not just the lines.

Hi Al,

Interesting experiments!
I like the soft shadows in the first post a lot. A plugin that can output this effect as a .jpg would be great!
