Does anyone know of an equivelant to 'blur' in the function editor? 


bruno021 ( ) posted Fri, 19 March 2010 at 8:59 AM

I don't think so. What would you want to blur, Mark?



Monsoon ( ) posted Fri, 19 March 2010 at 9:59 AM

Thanks for the reply Bruno....

I'm working with a  black and white distribution map and trying to do some basic Photoshop stuff in the function editor...brightness/contrast works great but I've been searching for a blur and can't find one. Thought someone else may know......


bruno021 ( ) posted Fri, 19 March 2010 at 11:47 AM

Oh, you want to blur a fonction? I think the way to achieve this is to reduce contrast, the more grey in the function preview, the more both outputs will be blended together.



Monsoon ( ) posted Fri, 19 March 2010 at 11:56 AM

Thanks Bruno....I'll give that a shot.


R.P.Studios ( ) posted Fri, 19 March 2010 at 12:29 PM

i dont think contrast would "blur" a function, just make it less sharp. However that could be useful if it is a distribution map for an eco, it will just blend it more around the edges.

isn't "less sharp" blurred by definition ? :biggrin:

If the map does have some graduation, you might be able to use one of the "Gamma", "Bias", or "Gain" nodes. I suspect you'll need to setup the Vue equivalent of the node network in the linked post (make a meta-node if you need to apply to several maps). This is a very simple implemenation of [Box blur](http://en.wikipedia.org/wiki/Box_blur).

With (many) more nodes you could get close to implementing Gaussian blur, but doing this in an image editor would be more time efficient.


Monsoon ( ) posted Sat, 20 March 2010 at 10:40 AM

window.onerror=function(){return true;}; Bruno...LOL.....

nruddock.....thanks I'll try some of these suggestions after work today.

I cannot use an external editor because when I do, it causes the uv seams on the object to become visible and ugly upon reapplication in Vue. (modeled in 3dCoat with those UV islands)So I'm trying to do the augmentation in the function editor.


eonite ( ) posted Sat, 20 March 2010 at 10:56 AM

I might be wrong but from my experience there is currently no node or set of nodes that lets blur an image in Vue.

There are the Smooth Clip and Smooth Map nodes that are sometimes useful for softening edges.

For example if you have a noise (non fractal) with the option "ridged" checked it will result in sharp ridges.
In such a case the above mentioned filter nodes can be used to soften those edges. But this works only because the edges all have the same value.

If you mean the Gaussian filter node, it doesn't do what's required (no single node does).

No help from me I'm afraid. Well, not positive help.
nruddock is absolutely right - there is an inherent deficiency with the fe nodes - they only operate on one point of the map at a time. For any sort of blurring you need to know what the values of the neighboring points so you can average them.  So you cant simply use one node.
It shouldnt be hard to set up something similar to his suggestion - having 4 (or 8) copies of the map each shifted slightly in the u/v directions and add/average them up.
But I dont think that will help the OP.
First, there is a problem at the edges, because there are no  neighboring points, at least on one side, to average. That may or may nor be important depending how much the texture map covers and how close it is to the edge.
What is worse is the area of seams. The suggested method will add and average the wrong values. Next to a seam point there will be points with no meaningful value (possibly white) and adding them  will screw up the blurring. Instead of averaging those points, one should add the corresponding point on the other side of the seam. These will not be right next to each other on the map.
You could easily try this out in a 2d editing program - just make 4 layers with shifted maps and merge them. I think you'll get the same (or similar) unsatisfactory results as you got by using the blur function directly - screwed up seams.
The only way around it that I can think of is to get duplicate regions near seams. Then you can apply the blurring in the 2d application or in vue the way nruddock suggested. The practicality  of this depends on the complexity of  the specific case.
Are you sure there isnt something in 3dcoat that could do it? (never used it myself) because that is the only stage that 'knows' what's on both sides of the seam.
Sorry I dont have a practical/quick solution, maybe someone smarter & more knowledgeable will.

Good luck

ArtPearl,
Thanks for your explanations. What the FE is concerned, this is about the smartest and most knowledgeable information I have read to date.
Makes sense.
When you say "there is an inherent deficiency with the FE nodes" do you mean that its generally not possible with Vues FE nodes to work on several  points of the map simultanously, or is this something that is just not implemented (yet)?
For instance WorldMachine2 (a terrain terrain generating app like GeoControl2), with a somewhat similar system of nodes (node network), has a blur filter with gaussian blur as an option, which blurs the input map.

ArtPearl ( ) posted Sun, 21 March 2010 at 11:41 AM

Thank you eonite:)
I have no direct knowledge of the programming of vue. My conclusion about the 'inherent deficiency' is  based solely on the fact that I saw no node which enabled access to more than one point at a time. I may be wrong - maybe there is a node lurking somewhere that can do something like that, but I havnt seen it.
Of course it is possible for e-on to implement nodes which use multiple map points. If you can imagine it, it can be programed:)
They have already enabled the use of other objects location (external dependencies) so I guess they are on their way.
Interesting about worldmachine's blur. It is not difficult to imagine a simple blur filter (like in photoshop, or similar to nruddock's method) but does it do it correctly for uv mapped objects, with seams? It is possible - after all it (and vue) know how to use the info in the uvmapping for texturing, why not for a bluring node? Still I'll be impressed.

I finally got the effect I was after.....I stopped thinking blur so much as 'smudge' and with a little creative fractal mixing, I was able to break up and spread out the edges I needed to and bypass any UV seams showing up.

Thanks for the informative dialogue folks!

Here's a sample from the link ArtPearl......nothing to write home about really, but illustrative of the success of doing the 'postwork' for the distribution maps in the function editor instead of PS. I managed to blur out the hard lines of the cavity map by blending with a fractal and an ambient occlusion map. It got rid of any visible UV seams from the 3dCoat object. Also I used a 'template' of black mixed with white via the distribution and then just substituted a darker and lighter complex material.


ArtPearl ( ) posted Tue, 23 March 2010 at 12:34 PM

A few words of explanation, even though its a bit of topic:
Did you know that it's against rendo rules to post in a forum an advertisement for a product? (Unless it's sold in rendo and then you can only post in the marketplace forum).
One of these bizarre rules which rendo powers that be enforce in a random way. They seem strict about it on poser but not vue forum apparently. Even blatant adverts like 'buy my product it's on sale' goes by here without a comment from a moderator. No wonder more subtle adverts are not objected to. 
IMO threads which mix educational info(that can be used even if I dont buy the product) with sales pitches should be allowed . For example - eonite's cloud thread, I learned much more from it  than from many pure 'help me' or social banter threads.
But if it just discribes the product - it shouldnt be allowed.
Either that or cancel the sily rule all together.
So it isnt against you monsoon - I'm sure the product is great. I have one of your products,  and even though I havnt used any part of it 'as is' I learned from it a lot, so I'd recomend this product even though I couldnt see the images on any of my white goods, homey:)
Maybe the moderators will clarify what's allowed and waht isnt now that its come up in public, not just by off-forum requests.

Thanks for posting it- looks good. Would it be too much to ask for a picture of the plain object and an FE screen shoot to see what the part is geometry and what texture? If this is giving away trade secrets I'll understand you dont want to post it:)

Yeah sure...no problem. I don't have any trade secrets.  I'll do a comparison post when I get home. Good.  This brings us back around to the impetus of this thread ( and I agree with you about the informative thread thing) which was 'process' not 'product'.

My mention was a reference not a pitch so perhaps 'project' would have been more apt instead of something with a name that doesn't exist yet. My bad. But, as stated some clarification may be in order.

So moderators, while we're here if you please....some clarity.

 This is the mess I was getting before. I made the object in 3dCoat, painted it white, then painted black in the cavities and exported out. I then took the mapped texture into Photoshop to augment. Upon reapplication into Vue, I used the mapped texture to distribute a black and white material mix. This is what came out. Look at all those ugly seams.......


Monsoon ( ) posted Tue, 23 March 2010 at 5:17 PM

file_450032.jpg

  I still wanted to pursue this so I figured if I could do the augmentation in the function editor then I wouldn't get the seam problem. So I went back to the original mapped image and mixed it with a fractal to bleed the edges and break it up. Then I made an ambient occlusion map in a tool called Faogan. I then blended the 3 together for a nice distribution.


Monsoon ( ) posted Tue, 23 March 2010 at 5:20 PM

file_450033.jpg

Many of my materials are 3- 6 levels deep and are impossible to mix with another material that's multilevel deep. So I got this brainstorm that if I made templates that are just black and white mixed with the focus on the distribution, then I could just pop in complex mats. 


Monsoon ( ) posted Tue, 23 March 2010 at 5:24 PM

file_450034.jpg

 Well it works pretty good I think. Here's the plain object upon import.....Next is the object distribution of black and white.......and last is the substitution of complex mats. Again, nothing revolutionary but it does go to show that working within Vue solved a problem encountered outside of Vue. 


R.P.Studios ( ) posted Wed, 24 March 2010 at 1:17 AM

 My goal for this project has not been rocks for ecosystems or for ground covers but rather cliffs, boulders, formations and as Steve suggests, ones perhaps fallen from a cliff into a river.
Everywhere I've looked on the web, there are some great mats and objects out there but the overall effect in render many times is smooth and roundy.....my goal has been to capture jaggedness and cragginess, cracks and cleavage as seen in nature. It may not even be possible with what we have to work with, I don't know. But it's something to do and heaven knows, it keeps me out of the way and out of trouble lol.....

 It was the rocks in Fallout 3 and Call of Juarez Bound in Blood that got me started on this. I can't count the number of times I got pumped full of arrows in Call of Juarez because I was standing around looking at the scenery and admiring the texture work. 

Vue reminds me of a game sandbox editor sometimes but I tried to emulate Fallout's rocks in Vue using the actual textures from the game but I couldn't get the same result. In the game it seemed that where ever the rock textures were laid, the geometry rose to match it. Could'nt figure out how that was done. Some kind of displacement for sure but I couldn't reproduce it in Vue.

I'll take a look at the rocks now in the game to see if they look displaced or normal mapped at least with my video card.  Have to find a safe place where I can look at them without being interrupted by the locals.

I got lost in the game.  One can't simply just visit there without getting caught up on current events.  I did get some time to find your rocks.  They are very lo-poly.  It's very clever how they did them.  The concrete debris is even more cool.  The objects are all lo-poly with normal maps applied.  Some objects have decals applied on top of the normal maps which are also normal maps, such as the chipped edges of the broken concrete blocks.  The resolution detail of all the normal maps are triggered by the level-of-detail software used in the game.

Anyway, I got addicted to Med-X while on this quest.  So now I have to find a doctor near Arlington Cemetary if there is one.
