Hi,
Version 1.3 has been released with support for filled closed polylines and for generating a closed polyline from points.
Please note that there's a known issue where closed Bézier curves are sometimes not filled correctly. This will hopefully be fixed in a later version. A workaround can be to slightly move or rotate the points.

Hi,
I've released version 1.2 now which supports filled closed Bézier curves.
Support for filled closed polylines will hopefully come in a later version.

I'm curious about this as well, I think it's been like this since at least version 17.

You're welcome LukeP!
I've released version 1.1 now which supports adding thickness to the curves and it also auto-detects if the geometry contains closed curves/polylines.

Hi Mike_A,
That's a limitation of my tool, the generated SDF doesn't contain any "inside" values, so there's nothing to fill. I'm checking if support for this can be added.
If you want to fill a closed curve, one way to do it is to append a "Convert" SOP node after the curve (inside the "SOP Import" node) so it gets converted to triangles, then append a "Rasterize Geometry" node after the "SOP Import" to get a filled shape.
If you want control over edge antialiasing and smoothing, append a "Mono to SDF" and an "SDF to Mono" node.
Hope that helps!

Hi all,
I've made a new tool called SDF from Curves for Houdini 20.5 Copernicus that generates a 2D signed distance field from Bézier curves, polylines, or points. I hope you'll find it useful when making textures!

I've updated the asset to version 2.9.
- It's now possible to display a screenshot of the selected screen in the viewport.
- Color hue/saturation/value/brightness can now be clamped to a specific range and colors can be removed if they are outside of the range.
- Various minor changes and fixes.

Hi!
This is my entry to the Houdini Utility category:
Color Sampler
Description
Sampling colors is usually done by manually clicking on an image or the screen, one color at a time.
The Color Sampler asset can automatically sample multiple colors from an image/screen.
Points are generated over the image/screen and then each point samples the color of the nearest pixel.
The colors are then stored in a color ramp.
Manually sampling by drawing on the image/screen is also possible.
It also allows modifying the colors in various ways and the colors can be exported for use in other applications.
Features
Use cases
Version: 2.8

The colors are then stored in a color ramp.
Manually sampling by drawing on the image/screen is also possible.
It also allows modifying the colors in various ways and the colors can be exported for use in other applications.
Features
- Sample pixel colors by drawing or generating points on the image/screen and store the sampled colors in a ramp.
- Resize and blur the image.
- Sample all pixels between two or more points.
- Snap points to pixels.
- Sample raw or filtered (interpolated) colors.
- Sample unique colors.
- Sample the most frequent (or dominant) colors by grouping them by similarity or by counting the occurrences of each color.
- Draw on the screen: manually draw points on one or more screens. Inspect pixels by showing color values, pixel coordinates and sample count next to the cursor. Enable/disable/remove strokes.
- Draw in the viewport: manually draw points in the viewport to sample the image/screen. Resample and enable/disable/remove strokes.
- Line sampling: use points on one or more lines to sample the image/screen. Set the line positions using local space coordinates or pixel coordinates which allows for exact positioning, rotate the lines and extend the lines to the image/screen bounds.
- Grid sampling: use points on a grid or sample every nth pixel of the image/screen.
- Random sampling: use randomly distributed points to sample the image/screen.
- Input sampling: use points connected to the input pin of the node to sample the image/screen or keep the existing point colors.
- Get the average sample color and average image color.
- Sort colors by hue/saturation/value/brightness.
- Compare colors using "Lab Delta E CIE94", hue, saturation or value/brightness and remove colors that differ less than a specified value.
- Override the sampled colors by setting/adding/multiplying the hue, saturation or value/brightness.
- Translate all of the colors in the ramp and optionally repeat the positions at the start/end of the ramp.
- Apply noise to the position of each color in the ramp.
- Scroll through the colors in the ramp.
- Display samples in the viewport as points/nulls/circles/planes/boxes and as color swatches.
- Set the sample size to the pixel size.
- Set the image transparency and filter: "linear" for smoothed colors when zoomed in or "nearest" for a pixelated look.
- Set the max number of colors that can be stored in the ramp, shown in the viewport and output from the node.
- Export the colors to an image: either as the swatches shown in the viewport or as they are shown in the color ramp. Set the image size and the number of pixels per color.
- Export the colors to a JSON text file: store the colors as float values, integer values or hex values and with a color ID.
- Fully documented parameters.
- Node type: SOP
Use cases
- Link the color ramp to other ramps to apply the colors to textures or geometry.
- Create color themes.
- Modify existing point colors.
- Export the colors for use in other applications.

Hi,
I've just released version 2 of my Rock Generator asset.
Major new features include a new type of displacement to generate cracks, greatly improved UV generation for arbitrary meshes and a new material.
You can see more info at http://techie.se/?p=gallery&type=houdini_assets&item_nr=1 [techie.se] and download it from https://www.orbolt.com/asset/Techie::rock_generator::2.0.
Kind regards,
Techie

Thanks a lot wildruf!
There's some really nice rocks in that thread, I'll see if I can implement something similar.

In case anyone is wondering, I asked support and they said that the only way to create a function in a VOP network is with a digital asset.

I have two small requests: please make the new smoothing tool available as a node (or update the existing one) and add check boxes in the Edit node for the “Make circle”, “Evenly space selection” and “Straighten selection” commands.

Looks like an epic release! I'm really looking forward to the new boolean and smoothing tools.
