James,

Got through a couple major steps. Learned how to add an image to a node from the file UI. <No documentation to reference...>

Converted Max's height map code to the Node. Learning how to output massive data through the port. Learning Javascript...

Many things to do before a beta can be tested.

Wayne

Wayne,

Your WIP node looks fantastic!

A couple of thoughts:

* Try low res image (say 60px x 40px)
* Also instead than connecting output to circle node, try Points/ConvertPts (Mode: CurvesU)

Let me know the result.

Keep up the good work

James,

Thank you. Max's heightmap program outputs the CurvesU and CurvesV in a line sequence while the ConvertPts component (CurvesU) outputs in XYZ-XYZ etc then draws a line back to the next XYZ step up from the far point. The CurvesV setting did not output anything.

ConvertPts might be updated to a new conponent ConvertPts2 for resequencing the points in a line order.
Unless there is an existing Node component that is being overlooked.

Wayne,

Thanks for getting back to me. Did using a low res image input reduce the output number of points?

>> Unless there is an existing Node component that is being overlooked.<<

"Points2/PointsExt" node can be used to order a single point Arrays into a sequence of discreet arrays, however it necessary to know the xLenght, yLenght & zLenght. Assuming the point output correlates with the image input, a 60px x 40px image will be xLenght = 60, yLenght = 1, zLenght = 40.

To connect pointArray output to "Points2/PointsExt" node, use "Points2/SplitPts"node as intermediary
(only x y & z outputs need be used).

If this is a bit confusing, DM your beta js file & I'll demonstrate.

Thank you for your tireless efforts

James - FYI: Test program has been sent to your private mailbox.

Seems very cool !

Wayne,

In my original proposal for ImgSampler (http://moi3d.com/forum/index.php?webtag=MOI&msg=9581.2) I had a point array input to dictate the numArray output length, perhaps this was the wrong way around. Maybe it would be far simpler if instead the image size determined the U & V dimensions of output point array.

Ideally then the image resolution could be varied dynamically with dialled input so that a higher res image may be imported and pixelated to suit the desired point array data. There is a lot of information available for pixelating images with JS & HTML online.

Essentially, this entails reducing the image size while retaining the display size with imageSmoothing disabled.
The pxWidth & pxHeight would then be the Unum & Vnum of output pointArray.

UPDATED:
It might be useful to also include inputs for Urange and Vrange to set the size of the output grid of points.

Working on it.

Does it possible to have something who gives in real time the Mouse's cursor x,y,z on the screen's work ?

Offset DotScreen as desired for rasterImage output may easily be achieved with split node
and Remapper node allows for adjustment of image contrast.

New ImgSampler Node release

This node uses Max's heightmap routine for converting an image to data points.

Copy the ImgSampler.js to the directory:
C:\Users\<UserName>\AppData\Roaming\Moi\nodeeditor\nodes\extensions

I would like to thanks James for helping out with testing and some fantastic node designs.

Updated. Added curves for lofting 3d surfaces from image.

Congrats to your latest node contribution...I was so happy to help.

ImgSampler will be very useful, not just for 3d modelling but also for 2d graphic design (eg signage:
cnc router or laser cutting).
I have been contemplating using ImgSampler for creating a Line Screen Image as per copperplate etching.
When it came to doing it, it turned out to be so simple.

So, thank you so much,
James

James,

This one is great. That pattern style is going on my CNC router today.

Thank you, Looking forward to another node development.

Great NODE guys, please excuse my ignorance but how do you load the image into the node?

Also for some added inspiration on this tangent have a look at

Hi Wayne
If i test your node i haven't the same result
look at my screenshot
Thanks

HI AlexPolo,

Just mouse click inside the picture frame to load an image. Set the resolution of the image before loading the image. It is the first released version. Improvements will made from user feed back.

I will check out the referances.

Wayne

Hi Finema,

Set the resolution of the knob, then reload the image. I will be making improvements on the interface.

Thank you,
Wayne
