example: www.shadertoy.com/view/Dst3D2

click to rotate through hue cycle

if you want a non linear distribution, change line 53 to something like `return pow(min(distToCenter / spokeLength, 1.0), 3.0);` or `return pow(min(distToCenter / spokeLength, 1.0), 0.25);`

the simpler version which is linked on the shadertoy comments, if you change line 63 on that bad boy you can see the distance from the offset center to the boundary parameterized to 0-1

“the spokes”

someone said , group + blast is much faster than an if statement + “removepoint()“ so I ran some tests (20 million points) and it is indeed true, although the absolute fastest is grouping using an integer attribute instead then doing “ @my_attrib>0“ in the blast (0.174 seconds compared to 1.594 for “if + removepoint()“, maybe this is helpful to someone 😄

“`nodes = hou.selectedNodes()
#get pane editor = hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor)
#reset images
editor.setBackgroundImages([])
#get images
b_img = [img for img in editor.backgroundImages()]
for node in nodes: for parm in node.parms(): if(len(parm.keyframes())>0): #create image img = hou.NetworkImage() size = node.size() img.setRect(hou.BoundingRect(-2,-0.5,size[0],size[1])) img.setRelativeToPath(node.path()) img.setPath(‘$SIDEFXLABS/misc/stickers/emoji/SIDEFX_CUSTOM_EMBLEMS 08.png’) b_img.append(img) break editor.setBackgroundImages(b_img)“`

use this one instead

takes the size of node in consideration

@mestela `Sure! Here’s a short rap about Matt Estela:
Verse 1: Meet Matt Estela, the man with the plan He runs Cg Wiki, where graphics fans Can find all the knowledge they need to grow And learn about Houdini, the software pro
Chorus: Matt’s got the skills, he’s got the drive He makes the graphics come alive With Houdini in his hands, he’s a king Making stunning visuals, that’s his thing!`

I uploaded some source files to ikoon.gumroad.com I hope that it is ok to share them, it is mainly your work 🙂 I just made it into squares and put some grey background. I always try to keep credit and attribution to the original author, but if you find your work without reference to yourself, please let me know

(If someone would pay, I will forward the money to Patreons, who also share Houdini knowledge and source files, but do it much better than me here)
