I am posting to two places, one here and the other on the lsp forums.
Here is a thread from there:
The targets can be any shape. Currently i have modeled megatrees and a flat plane. I will also make a snowman of three spheres just to show how it would look. a 10' tall snowman, hmmm.
anyways the math models are independent of the targets. in fact you could have many target objects, say 2 mega-trees next to each other, and the projection from the math model could be projeted onto both at the same time.
Just need the math model and the target models to be close to the same size. Currently i am using a 10' high cone with a 5' diameter. I then have modeled the physical megatree 10. tall and 5' diametere. i move the model on top of the target and do a match to the closest pixel.
I find the closest pixel by doing
dist = sqrt((xm-xt)**2 + (ym-yt)**2 ++ (zm-zt)**2).
In any direction, dist is now how far apart the pixel is from the source model.
xm,ym,zm = coordnates from the math model
xt,yt,zt = coordinates of the models.
I am thinking of reaching out to jr colleges or high school math departments and see if their students might want to think up some of the math models.
I have an idea of how to do snowflakes, garlands. I want to get as many different models as we can.
The source model could come from something other than math models.
For example: maybe use a tablet and store the data as people write. You would then see whatever was drawn projected onto the target models.
other things maybe would be to read avi files and project onto tthe targets
right now, i just wanted to get the math models. For example the single spiral you see has a single parameter to it to add more spirals. 3, 6, 12? Model is built projection is the same. It is these more complicated models where i think it is a valuable tool.
So this is basically an effects generator which is an exciting prospect for LSP, I hope this feature will be able to be used on more than just a mega tree. I would like to see the same features as with transitions where you can map those generated effects to either an element or the whole display.
This then would really make it a madrix competitor and take LSP to the next level
Thanks for the great work and input, im sure the community will be much better off with your input.
