Excellent work and its spurring me on to build a mega tree sooner than planned.

One option that I'd love to see is "fractals" - snowflake algorithms implemented, random and colour changing
Dont know how practical - keep up the great progress

I have fractals on my list of source models.

I already have modeled snowflakes rotating around the vertical axis and dropping down at a 45 degree angle. These are all just the ability to redraw a 3d object  about an arbitrary axis. You can do rotations about two axis's at the same time.

I have an idea for garlands on the tree and have them dropping down into position.

I also have modeled the meteor effect, i will need to see how it maps to an actual target,
right now working on getting three different xml file outputs (LSP,LOR and Vixen)

thanks

Steve, this is exactly the info i need. I have already modeled your tree as one of the targets.

And for a future models of where i will take this, take a look at

This is how gnuplot can animate surfaces with color maps. Image this animation being projected onto your tree and you get an idea of where i want to go with rgbsb

Since mant peoples trees do the lights from the bottom to top as #1 channel at bottom is that possible?

You would have to have duel cones facing each other, it would look like a tree upright, and one inverted downward right under it.

"Since mant peoples trees do the lights from the bottom to top as #1 channel at bottom is that possible?"

Yes, i have already built these models:
1) Pixel #1 at bottom
2) Pixel #1 at top
3) Pixel #1 at bottom and wraps over tree and goes down the other side.
4) Start Pixel#1 and go down and move over one strand and then come back ending at the top again. (LOR calls this a wedge)
5) I have modeled half trees

You could have one strand go up and down three times if you want. I wonder if anyone has done those trees.

You can also give me an ascii file with the x,y,z locations of your custom shaped tree.

I am making the rgbsb web page build the models for #1 thru #5.

thanks

I am not sure what u mean. I create one cone for the source, say 20' high and 10' diamter. I create a target megatree where every pixel is located in x,y,z space. I then mathematically move the source on top of the target and match the nearest pixel to the data of the source model.

I have no  inverted cones.

maybe i misunderstood?

Like in the picture, Have the channels start in the center, and go down the cone from the center, or go up to the top. It would have that bounce up and down effect.  It was just a thought I had, kindof stupid i know.

Ah, i see

I can model that as a target if someone actually wanted to make something like it. I probably have enough for now just modeling the many ways people build trees.

I would be interested to see the trees that have already been built.

Great this will be an amazing tool!!!

  • ahhh, yes... my new blink-i-nator 3000!!!
my smart string tree last year started at the bottom. went to top, then back down one strand over. I think this is common.
To rule the entire tri-state area!  What's that? Perry the Platypus!!!

Hi all;

I have a new release of code that will build the target models

You are not allowed to view links. Register or Login

Please give any feedback on if this looks like it will cover your megatree.

 you can use 'guest' password 'welcome1' to just play with the tool.


So here is what i plan.

This page has a mysql db backend.
I expect you to be able to describe your tree with the prompts i currently have.
After you save the form , your tree will be saved under your name.

Some caveats.

1) The actual target models wont show up for you yet.
2) You cannot edit the model after you save it. Edit capability will come next week
3) I will export the models each day so that i can reload them as i am changing the database DDL. In other words, you wont lose what you enter.
I really dont think it will be that big of a deal since i think you can describe your tree in less than 60 seconds using this form.

I will be adding the ability to have other topographies. One that i saw on Madrix is what they call the snake. This means you could go up and down 5 times , for example. I think i cover what most of you do.

I have prototyped scrolling text on the source cone, so that will be coming out after i get the xml files out. I needed this model to continue my tests.

If someone is able to put their tree in matching your actual tree, please let me know. Ill use those in my testing cases.

thanks

I have though of the first issue where ny model builder may be incomplete.

Since, i have never built a tree, i am just guessing. I think maybe i will need to allow you to skip some pixels at the top of the tree.


This assumes spacing of 3" between pixels and a 9" diameter top of the tree.
In this case i think i need to ask
"How many pixels to skip at top of tree?"

This would only apply to the model where you go up and down the other side.

If you go up and come down on the adjacent side, maybe you will need to skip 1?

Again, i am looking for feedback to see if i have asked enough questions to model your trees?

thanks

I don't skip any doing it adjacent. 42 nodes up and 42 nodes down.
