Noodly-Line Solver (Houdini VEX) So I’ve seen a lot of tests of this effect recently, and thought I’d jump in and do my own version.
The very first time I saw the noodle solver was in this video by Deskriptiv over a year ago. Then when recently Simon Holmedal posted this test, it got me kind of curious. Finally yesterday I stumbled upon this video by Jan Fischer, and after reading the description I realized that it’s actually a pretty simple system. So to recap Jan’s write-up on the system: there are basically 3 forces that gets integrated by the solver. First force, is a vector pointing in the opposite direction to the average position of neighboring points. Here is a short video of the effect in motion. Source file here.
Houdini Video Tutorials — Arthur Yidi. ANDREAS BÖINGHOFF. Hey all there, when it comes to do fluid simulations in Houdini it is often necessary to be able to re-time the caches after the simulation.
In principle that is not a big deal – just an interpolation between two frames. It gets a little harder if we have a constant emission which leads to a changing point count. In this case we have to build a setup like this. First we start with a Null that gets three float Parameters as a input (Current Frame, Frame A and Frame B).

Surely someone has uploaded more polished solutions since then. Blueprint screenshot with comments: Full project - - just select a GenBuilding object and change its Height variable value. Meshes are marked as Static, so the lighting can be baked on them as normally :) It's a great feature of UE4 to have auto-generated stuff behaving like it was an imported mesh.

OpenGL @ Lighthouse 3D - Terrain Tutorial. This algorithm is a very simple one, yet its results, although not the best, are pretty good.
The technique is not limited to planar height fields, being also applicable to spheres to generate artificial planets. Paul Bourke and Hugo Elias have posted tutorials on the application of this algorithm to spheres. To start with we'll have a planar height field, where all points have zero height. Then we select a random line which divides the terrain in two parts (in general these parts will be different in size).
The points to one side of the line will have their height displaced upwards, whereas the points on the other side will have their heights displaced downwards. The red points will have their height decreased, whereas the blue points will have their height increased. OK, now lets look at the terrain itself after the same number of iterations.

Houdini Tutorials > Creating Your Own Custom Pyro FX in Houdini Tutorial. Volume Workflows. Used as a hint as to whether the volume should compute indirect illumination inside the volume (also known as multiple scattering, because light will scatter more than once inside the volume). If the multi scatter parameter is set to 0, and the integrator respects this hint, PxrVolume will only perform single scattering: points inside the volume will only be lit directly by light sources. If set to 1, points inside the volume will be lit by indirect illumination as well.For very dense volumes with high anisotropy, it is often the case that light will scatter many times inside the volume before reaching the eye, and multiple scattering is the only way to achieve the correct look.
It is also often the only way to correctly render certain effects such as volume caustics. Grand Tour: Project Overview. Tags : RMS 19, physically plausible shaders, image based lighting, gpsurface, glass, volumes, character, hair, fur, primvars, PTEX, vector displacements In this eight chapter "How To" guest contributor Leif Pedersen will break down a production pipeline in RenderMan Studio and RenderMan Pro Server.
We will specifically focus on the advantages of RMS and how it can help us decrease setup time without compromising efficient render times. We will divide the training into two distinct approaches to rendering via RenderMan Studio's RIS and REYES rendering architectures. The training will cover the interactions between RMS and Maya for general rendering workflows, Mudbox and Zbrush for importing texture and displacement maps, as well as Fusion and Nuke for Compositing. With this in mind, previous experience with these applications is helpful. Bullet physics implementation and other stuff - SideFX. Untitled. Eetu's lab - Work in Progress.
HOUDINI OTL : normals on curve! Hi everyone ! Yes that’s true , we are talking about Houdini. I have been a long time Maya user , I started back in 2006! Bullet physics implementation and other stuff - SideFX. Tom O'Bready on Vimeo. March 2014 VHUG. I presented some Flip and Point Advection stuff at the March 2014 Vancouver Houdini User Group. The files are here for anybody who was there or anybody interested: VHUG file (200 something megs.
This has the hip file and also the quicktimes and one frame of geo from the rest field setup) Fliptricks hip file Pyro Point Advect / Color Volume file I have two hip files. The second is a setup that uses Gas Advect to advect points along with a high velocity pyro sim. Flip Tricks (VHUG – March 2014) from Ian Farnsworth on Vimeo. Rnd_textureflow_pt1. In our latest feature movie I have developed a lot of procedural animated water surfaces. Starting from small puddles to huge ocean surfaces - all this stuff was created using procedural custom noises, including Houdini Ocean Toolkit and 2d ripple solver. For a few close-up shots I used FLIP simulations sewed with animated plates. To enhance spatial details I used texture displacement projected with a simple planar projection.
So next I faced the task of creating large scale water simulation. After making some tests I came to conclusion that I can not avoid using texture displacement. Eetu's lab - Work in Progress. Additive and Subtractive Color Mixing. The world is full of colors. Some researchers report that humans can distinguish about 16 million different colors. But what's more interesting is that most of the colors we see around us and all the colors we see on a TV or computer monitor can be created from just three different colored lights. How are all the colors made from just three different colors? Simply by combining the light in different ratios. That's it. Additive Colors Colored lights are mixed using additive color properties.
The additive primary colors are red, green and blue (RGB). By changing the brightness of each of the three primary colors by varying degrees, you can make a wide range of colors. Computer Monitors and Televisions Computer monitors and televisions are an application of additive color. Animated RGB Color Cube Here is an animated RGB color cube. Another Way to Make Colors Subtractive Color Mixing The subtractive primary colors are cyan, magenta and yellow (CMY).

Volumes are primitives Confused me slightly at first, so worth mentioning; A volume is a primitive, the same way that a point is a primitive, or a primitive sphere is a primitive. This means that unlike a polygon mesh for example, there's no drilling down to its sub-components; you can't open the geometry spreadsheet to see values in the individual voxels.
