Talking of COPs… (shameless plug)

@waffleboytom I made that demo i was talking about yesterday, and wrote a long comment in here explaining how atomic floating point operations work in ocl… Tweet: https://twitter.com/TearsOfJake/status/1748143788936286217

are you in H20? 😮

github.com/jakericedesigns/Assorted-Houdini-Demos/tree/main/HeightfieldTerracing here’s a link to the hip file

“`c float radius = chf(“radius”);
float dia = volumevoxeldiameter(0, “height”) / sqrt(3);
int voxel_rad = ceil(radius / dia);
float height_max = f@height;
for(int i = i@ix-voxel_rad; i <= i@ix+voxel_rad; i++) {     for(int j = i@iy-voxel_rad; j <= i@iy+voxel_rad; j++)     {         if(length2(set(i-i@ix, j-i@iy)) < voxel_rad*voxel_rad)         {             float height = volumeindex(0, "height", set(i, j, 0));             height_max = max(height, height_max);         }     } } f@height = height_max; “`

interesting

most of the japanese houdini advent posts are online, like every year, some fried gold entries in there: qiita.com/advent-calendar/2023/houdini

someone shared this in the cgwiki discord, an incredible collection of hips and stuff: https://twitter.com/WhiteDo27114277/status/1726265090117406728

the google doc that explains all the setups is wild, i think half the tricky questions that have been posted here, or interesting papers i’ve seen and thought ‘a houdini implementation would be sexy’, he’s done them all: docs.google.com/document/d/1HBQ6CwiDX0MbK7-nBrLU8hF8H08uPbewZF1z8ybdRw0/edit
