Loop 3D

Variations on this theme have been done before, but since it is a fun method, I thought what the heck, why not discuss the technique by itself: Creating 3D shapes using the Loop component.

Works just like a 3D printer, piling up one layer on top of another to build up something in the 3rd dimension.

Naturally something awesome, like a Blob.

Kinda like how they put MRI images together into a volumetric stack! Neat!

Not only that, you can subtract one object from another.

How about rotating the object while looping?

Precisely. With the added benefit that you can modify the image for every loop iteration.

The main problem being the slowness of the method.

I have a feeling you could also do this with the Bomber+, piling all the outputs into one position with offsets aided with the new extended density settings. For some reason I couldn't get it to work last night, but I'll give it a try again. Would be interested in seeing if there is any gain in speed using that method.

Cool stuff!

How does the attached one compare? It cuts the rendering time to 1/4 here.

Most excellent! I should probably compare it with mine, but... is it just the blur for bitmap caching or did you do something more to optimize?

Edit: Okay, I see, you blend the Accumulated directly with Threshold. And use the Position directly for fill, and, and...

Awesome stuff!

With some planning, it is possible to do just about any kind of 3D object. Here's a three-tube intersection. The insides are hollow and the inside openings are all connected.

Best 3d object in FF to date..

Planar option.

Faster as well...

The object was built in FF as well. Just that it takes a different way of thinking to build the object as you do it with height maps. The two pieces that are required to make the joint look like this, one "model" for the outer surface, one for the cut-out (negative space) inner surface. The filter then subtracts one shape from the other. As well as mirrors it to create the bottom side.

No ACIS boolean errors possible, YES!
No STL output? Oh.

CorvusCroax Spacehulk V2 Default Preset, wrapped onto a sphere (cylindrical mapping) + bump used for displacement = instant awesomeness - render time

Jumping Jesii!

If you make the scale squash a function of iteration, you can do perspective!
The problem with that is, some of the layers get really thin, so you need more iterations in order to fool the eye.

SpaceRay, when something is a function of iteration, that means a slave component for the Loop. Yes, I added one position slave component (click on the Loop component --> "Add Position").

Look at the Scale component near the Loop component. See how ThreeDee set the Squash = -50? That is what gives the image a diagonal top-down view. I connected the Position to the Squash input of the Scale component. That way, each "layer" or "slice" of the object can have a different perspective. In the Position component, I changed the Start and End values. Try experimenting with different values and see what happens. Remember that white = 100 squash, gray = 0 squash, and black = -100 squash.

When you edit the filter, try setting the number of Iterations to a low value so you don't have to wait a long time for the image to render.

After discovering how to make a vertical plane rotate around its center axis, I could greatly improve the speed of wireframing. Now it is possible to draw just the layers needed to generate the wireframe. Here's a basic version with just a couple of loop iterations.

Cool and great wireframe 3d models, well done, like it

How do you make the first wireframe lines to be looped after? uing the vector tool you have done?

Congratulations for the work and expanding the 3D inside FF

Thanks

I have a problem here. the ffxml files above are opening up in note pad instead of downloading. Is this somthing I'v done? I'm sure I didn't change the program that opens ffxml files. so what's up?

I don't get it. That never used to happen before. FFxml files used to just download and open into the FF my filters area. At least that's what they did in my software.

Thanx, that worked.

I'm a Firefox man. They just updated to 44.0. I don't know, maybe that's it.

TADA! That was the problem. When FireFox upd ated the other day for some reason it rese t that. Thanx! ( It also deleted the code for tabs on bottom. not even the add-ons for that work in 44.0. But that's a matter for another thread.)
