Searches the Houdini path for a file. findfiles. Searches the Houdini path for a file or directory. fit. Fits a value from one range to another. fit01. Fits a value to the 0-1 range. fit10. Fits a number in the 0-1 range. fit11. Fits a number to the -1 to 1 range. floor. Returns the largest integer not greater than a number. frac

fit01. Takes the value in the range (0, 1) and shifts it to the corresponding value in a new range. ... Produces the exact same results as the Houdini expression function of the same name. hscript_snoise. hscript_sturb. hscript_turb. Generates turbulence matching the output of the HScript turb() expression function.

RBF Interpolation in Houdini: What You Need to Know

Houdini and other graphics processing platforms heavily utilize interpolation in many of its operators and processes and is an extremely common process for computer graphics processing, ... – Fit(), efit(), fit01(), etc; Let's Get Technical. I’ve create this infographic below that can help with understanding the implementation of RBF. Feel ...

fit01(rand(@ptnum), -180, 180) Will give a different value between -180 and 180 for each point. You will find a lot more information on using Expressions, using random numbers in your expressions, and some interesting manipulations you can do using mathematical expressions in the Houdini documentation

One of the staples of creating Procedural models in Houdini is to add randomization to your systems. This helps make things feel more real. ... In VEX we can do this by using the fit01() function. This function takes a number between 0 and 1 and lets us define a new range for that number. Lets take a look at how this is used inside of VEX.

Posts about Houdini written by jarka chalásová ... @bend = fit01(random(@id),-1,1) * 60; @lenght = fit01(random(@id + 0.12345), 0.1, 1.9); 2. It is time for placing everything inside loop node preset. Because we want to give random bend to each piece of our example geometry that is currently being attached to each point of the line. We need ...

val = fit01( pow( val, 3), min, max); ... For Houdini the closest point in the same geometry is going to be itself. If we need the real closest point, we have to take not // the first, but the second element in the list (which has index number 1). ...

Houdini allows 'spare inputs' into a SOP node, which lets you reference external data from inside a For Each loop. For an example, let's say I want to scatter some points around the vertices of a grid. I want a random number of points at a random distance from each vertex.

The joy of xyzdist() and primuv() – Toadstorm Nerdblog

I’m going to try to make a nice easy introduction to my two favorite functions in Houdini VEX (besides fit01 and chramp of course): xyzdist and primuv.These functions are at the core of a lot of really useful and cool tricks in Houdini, including rivets, the attributeInterpolate SOP, the old “droplets falling down a soda can” effect, and some really awesome stuff with volume shaders.
