    I wrote an article that is probably only of interest for the .1% It is a crash introduction to HDK, C++ and the mesh laplacian. https://mbaadsgaard.com/portfolio/laplacian-eigenvector-plugin-for-houdini/ Feedback is, of course, also welcome

    A while ago, I was working on a project that had lots of animated tiles. It is actually quite a tricky problem to pack a bunch of shapes together with the smallest amount of "grout". While researching this, I stumbled across this paper "Simulating Decorative Mosaics" by Alejo Hausner, and thought this would be a perfect thing to implement in Houdini! Here is the input, the houdini logo: Also needed are curves that represent the color or element boundaries: Here is one iteration of the loop. This is basically the result you would get copying tiles using a scatter and copy sop: After running the loop for fifty iterations, the tiles seem to be pretty well packed, and are respecting the boundary curves very well: And lastly, here is a version with randomized tile sizes. Still works pretty well! While I never actually ended up using this in production, But I thought it was pretty cool and could be used for other stuff, like maybe packing houses in a procedurally generated map or something. Anyway, here is an example .hip file if anyone wants to play around with it: mosaics_example.hip

    I wrote a custom render engine in COPs today. While 'engine' is probably a bit far fetched, it's a little ray tracer experimentally supporting: Meshes with UV coordinates Shading on diffuse textures Multiple point lights (including color, intensity, size) Area shadows and light attenuation Ambient occlusion Specular highlights Reflections with varying roughness The snippet basically transforms the pixel canvas to the camera position and shoots rays around using VEX functions like intersect() and primuv(). The rendering process only takes a few seconds. I still have to figure the licensing fees, though COP_render.hipnc

    Hi all, As some of you may know I have recently started a youtube channel where I am sharing some techniques, setups and tips. My goal is to first cover some of the fundamental tools/setups and then build more elaborate setups. I wanted to share this with the odforce community too as this community will always have a special place in my heart :). Thank you for watching & have fun learning! The channel: https://www.youtube.com/channel/UCZMPkkgnAFghvffxaTh6CsA My first video:

    I learned quite a bit from this tutorial as I have just recently started to learn Houdini. I took it a bit further and also applied the same or similar techniques to other variants. Rendering done in Renderman 22.6 Thanks, Ben P.S. I also could not see sprinkles sunk into the surface on my real world samples Quite the contrary in fact, the coating was reaching upwards by surface tension around the sprinkles by a tiny bit - which is what I tried to replicate on the donut with the pink sugar coating.

    I want to start spending an hour everyday to just explore simple stuff in Houdini. This will be areas I probably feel I lack a little understanding, as well as ideas I have had but never really executed. Hopefully some form of render will emerge from every little exercise that I do. Last night I had a quick dive into vellum and played around with some Cloth. Rendered in Redshift.

    Hey everyone, so after my very long thread (https://forums.odforce.net/topic/44053-implement-kernel-maths-in-vex/) I finally found a solution. The setup works great at 0.05 res, you might have to dive inside the solver and change some parameters to get it work at other resolutions (especially to get the droplets). Here are some test : Emission threshold at 60 (depending on the situation, there might be some abusive expansion, like at the end on the rubber toy, but this seems impossible to fix when you want a full thin sheet) Stretch threshold at 0.75 / Surface Tension 0.5 Emission threshold at 15 / Stretch threshold at 1.25 / Surface Tension 1 Houdini default Flip with Surface Tension at 1 Crown test with 50 Emission threshold (problem with infinite expansion with liquid dropping from the collider) If someone has suggestion to improve it, feel free to tell me I'm still working on fixing the infinite expansion issue, but the emission threshold is doing great until 20-30 depending on the situation Cheers, thin_sheet_solver.hipnc

    Haven't seen 18 yet so don't know if the code editor was improved, but if not, this still is my ABSOLUTE NR. 1 wish. if(code_editor_improved != true) { Code editing in Houdini Wrangles is - well - crap. It's a total shame we don't even see command parameter lists when typing since even in value fields typing expressions does it and has autocomplete for paths etc. Even only bringing that ability to the VEX editor would be very helpful. Of course it would also make a lot of sense to have other settings and helpers in there, like auto-closing brackets, more clever cursor positioning, offering existing variables and attributes when typing etc. - the Houdini devs should know ALL about that, they probably spend their life in real code editors... The use of external editors could be improved a lot if a.) we wouldn't have to press ALT+E twice for the external editor and wouldn't have to get to the floating editor first each time and b.) if that connection would be "live" like for instance the Pinegrow Web Editor does it with a little plugin for Code and Atom, where you can type in either the internal or external editor and they update each other in realtime. The current system is too clumsy and the 3rd party implementations also aren't really there (no negativity towards the authors intended at all!). Make it native! Make it goooooooood! } else { All is well. Nothing to see here. :-) } Cheers, Tom

    Did an experiment with subsampling the curve instead of adding extreme amounts of points to get precision. The downside is that you cant predefine the cuts with your own attribute. clip_by_noise.hiplc

    Hi RustyMac2020, may I give you a polite suggestions to: - give your threads a correct descriptive titles (like the one above instead of the original "What is the difference?") - avoid asking about things directly described in relevant documentation (like what does a given function) - avoid collapsing many unrelated topic into single thread - finally start using spell checker These are not to make life of a novice user harder, but to lower noise level and make public forum more useful. Thanks! btw documentation chapter about attributes (what they are and so forth): https://www.sidefx.com/docs/houdini/model/attributes.html

    This has come up quite often for me when working with imported static FBX files. Often you will get every little piece of a model inside it's own geo object but you really just want to work with them all as a single mesh. This script will examine your node selection and create a new /obj level object that will object merge in all the nodes selected into a single merge. Then you can just use that single node to represent your model. (i.e fix up normals, detail materials, prepare for simulation, export etc...) import hou THRESHOLD = 0.015 def luminance(pixel): return (0.299 * pixel[0] + 0.587 * pixel[1] + 0.114 * pixel[2]) def is_similar(pixel_a, pixel_b, threshold): return abs(luminance(pixel_a) - luminance(pixel_b)) < threshold lst_user_selection = hou.selectedNodes() if len(lst_user_selection): # Make a geo node that will ObjectMerge in all the nodes in the selection. node_geo = hou.node('/obj').createNode("geo","geo_merge_result") if node_geo: node_geo.moveToGoodPosition() #node_geo.node('file1').destroy() node_merge = node_geo.createNode('merge') node_merge.moveToGoodPosition() # Create a normal to fix up everything after the merge. node_normal = node_geo.createNode("normal","normal1") node_normal.setInput(0, node_merge) # Create a NULL for our output placeholder. node_normal.setDisplayFlag(True) node_normal.setRenderFlag(True) node_normal.moveToGoodPosition() # Create a NULL for our output placeholder. node_null = node_geo.createNode("null","OUT") node_null.setInput(0, node_normal) # Create a NULL for our output placeholder. node_null.setDisplayFlag(True) node_null.setRenderFlag(True) node_null.moveToGoodPosition() for (n,node) in enumerate(lst_user_selection): print node.name() node_temp = node_geo.createNode("object_merge",node.name()) node_temp.parm('objpath1').set(node.path()) node_temp.parm('xformtype').set(1) node_temp.moveToGoodPosition() assign_by_node_color = True if assign_by_node_color: # Use the color of nodes to inherit the same @shop_materialpath. s = "rs_DEFAULT" if is_similar(node.color().rgb(), (0.584,0.776,1.0), THRESHOLD): s = "rs_blue3" if is_similar(node.color().rgb(), (0.6,0.6,0.6), THRESHOLD): s = "rs_grey5" if is_similar(node.color().rgb(), (0.145,0.667,0.557), THRESHOLD): s = "rs_green5" if is_similar(node.color().rgb(), (1.0,0.725,0.0), THRESHOLD): s = "rs_yellow6" if is_similar(node.color().rgb(), (0.996,0.933,0.0), THRESHOLD): s = "rs_yellow5" # Create a wrangle to define our shop_materialpath. node_wrangle = node_geo.createNode("attribwrangle","attribwrangle1") node_wrangle.parm('snippet').set('s@shop_materialpath = "/shop/%s";' % s) node_wrangle.parm('class').set(1) node_wrangle.moveToGoodPosition() node_wrangle.setInput(0, node_temp) # Create a color to match the node color. node_color = node_geo.createNode("color","color1") node_color.parm('colorr').set(node.color().rgb()[0]) node_color.parm('colorg').set(node.color().rgb()[1]) node_color.parm('colorb').set(node.color().rgb()[2]) node_color.moveToGoodPosition() node_color.setInput(0, node_wrangle) node_merge.setInput(n,node_color) else: node_merge.setInput(n,node_temp) In this image the white areas were not part of the selection. The color of the nodes in the selection is forwarded into the object merge as an additional color node. There is also an attribute wrangle added inline to assign the @shop_materialpath based upon the color detected. This can convert objects with same exact material referencing multiple copies of the same material into a single /shop path material. You can adjust to /mat if needed.

    Hi tmac, you can move the internal point of a triangle to the border by applying the average position of its two other points to it: // in a primitive wrangle if(primvertexcount(0, i@primnum) == 3){ // make sure it's a triangle int pts[] = primpoints(0, i@primnum); // collect all points of the triangle vector pos = 0.0; // set a initial position value for summing up the other two points positions later int pt_move = -1; // set a initial point number for the yet unknown inner point foreach(int pt; pts){ // run over all points of this triangle if(inpointgroup(0, 'outer', pt) == 1){ // ask whether this point is part of the outer group pos += point(0, 'P', pt); // add its position to the position sum from line 3 } else{ // if the currently processed point is not part of the outer border.. pt_move = pt; // .. define it as the inner point thats supposed to be moved.. } } vector pos_avg = pos / 2.0; // .. to the average position of the other two points. setpointattrib(0, 'P', pt_move, pos_avg, 'set'); // apply the new position to the inner point. } Rising the roof can be done without promoting the polyframe`s egdedist attribute, simply by calling the vertex attribute within a point wrangle: v@P.y += vertex(0, 'edgedist', i@vtxnum); roof.hipnc

    Binding of mouse buttons for hot keys and what not Some mouses have multiple buttons that currently are unused. For example the back and forward buttons. These could be used to dive in and out of a node. Ability to intersect console messages using python that are send by vex (printf). For example this would allow for the creation of a python panel that intersects the console messages sort and colour codes them.Making it more useful as a debug tool for vex codes A better option for the Houdini console window. Currently it's just popping up and always in the way. If this would be a proper panel it could be doct like any other panel.

    Ok, I'll play. I'd love to see a 3D Camera Tracker/Solver as well as proper support for playback of Quicktime and DNxHD files right into the viewport. Blender has it, C4D has it, shouldn't Houdini have it too? I know that this is the type of specialized tool that is typically done by a 3rd party app like SynthEyes or PFTrack, but having a way to track basic video right into Houdini would be a time saver, particularly for not overly challenging situations. Anyway, I want it...so there!

    You need to use setCurrent method in hou.Node. For eg., say you've copy pasted some nodes in the geometry node called geo1 and to get back to the object level, just setCurrent on geo1. geo1 = hou.node("/obj/geo1") geo1.setCurrent(True) -J

    I have used this setup on a number of projects and thought I would share. Basically, it is a simple setup that uses the wire deformer and hair system to animate geometry. I used to do this all the time back in Maya using Shave and a haircut, and was surprised that there isn't a more straightforward method to do this kind of effect in Houdini. This is especially useful when you need to add flowers or other kinds of detailed grass to an existing grassy field that has wind blowing through it. grass_example.hip

    Thanks Noobini !! So here's just a new test after some new vex trials : I'm pretty happy with the result but it only works at the resolution 0.05, and with the minimum insertion threshold set at 0.25...

    This does not seem right. Most of the time forces are distributed pretty uneven based on the stress of the constraint system. I modified your scene a bit, to illustrate my point - as you can see all constrains are using the same break threshold (with the exception of both sides - I made them stronger on purpose, as they are most likely to fail), but only some of them are broken - where the forces are much stronger than the rest of the constraint network. You can expand on this and add different types of constraint breaks based on force, torque or distance between the pieces. Snap_Constraints_Example_2_MOD.hipnc

    @evilRainbow Hey sorry I didn't reply sooner. I'm posting an updated file that goes into a little bit more depth as to how orientations are computed by the Copy SOP, and then how to modify those rotations one axis at a time, all using quaternions. Basically the Copy SOP is going to try to do whatever it can to figure out how to orient your copies if you don't provide enough information in the form of template point attributes. An orientation requires a minimum of two vectors: the third can be automatically calculated by finding the cross product of the other two. Once you have three vectors, you have a 3x3 transform matrix, and so you know which way each axis (X,Y,Z) should be facing. If all you do is provide N, which is typically the case when you're just starting with any old geometry, Houdini is going to guess at an "up" axis by figuring out the matrix that would rotate world N (the +Z axis) to the current surface normal, and then multiply that same matrix by world up (the +Y axis). This "guess" in VEX is the dihedral() function. Then it will cross N and up to find the implicit third axis, and that's your final orientation. I'm doing that manually inside the VOP network "determine_initial_orient" here, converting it to a quaternion, and then binding the result to "orient". Quaternions and 3x3 matrices are interchangeable when you're just talking about orientations (matrices can also describe scale and shear but we won't get into that here). Next, the extra rotations... a quaternion can be described as an axis to rotate around and a number of radians to rotate around that axis. In the second VOP "twisting_manual", first we decompose the orient attribute back into N and up vectors by multiplying +Z and +Y by the orient quaternion... this effectively recreates the original orientation we did in the previous VOP, but now it's relative to a specific axis. Now we can just create a new quaternion out of that axis, and any angle we like; this will create a "twist" around whatever axis. Finally, all these new twists are combined by multiplying the quaternions together, and then multiplying the combined rotations by the original orient quaternion. You can try dragging the "twist" parameters around on that second VOPnet to see the sprinkles twisting around. You could easily modify this VOP to generate random values for the "angle" of both axes rather than using a parameter. Sorry this is so wordy but quaternions and orientation in general is a pretty complicated thing and I still only really understand half of it. There's more notes inside the HIP file... it's probably easier to just look for yourself and play with the settings. manual_rot_around_axis_toadstorm.hiplc

    Without seeing your hip file I can only take a guess. That plateau looks like you've multiplied up the density of what would have otherwise been a very thin or empty voxel. If this is the case you're sending density values greater than 1 into your shader which is often going to make your shading experience a bad one. The image below from left to right is. 1. The original simulation, with a density of 1 and a shader render density of 1. This is the sim's natural look. 2. This has a post multiplication of 10 before and a shader render density of 1. This is what I believe you've done and why you see the plateau. 3. This is the same volume, with a density of 1 and a shader render density of 50. This is the correct way to make a thin simulation render more dense without lifting the empty voxels. Either you need to lift the density emitted in your sim to begin with or make sure that you're working with the shader to change the look of the sim, not the actual density values Edit: This sim has an upward velocity of about 20-30. The leading edge is curved but when rendered incorrectly will look flat because the curve is very subtle. Cranking the density values before it gets to the shader erases the variance responsible for the curve. .

    I'd never pay that much to study. For that amount you could sit at home learning by yourself for a long time, get an internship somewhere and get into the industry that way. $41k is crazy. I dont know how the industry looks like over in america but yeah, if thats the norm I feel sorry for you guys.
