motion trails in houdini, part 1 » Toadstorm Nerdblog I haven’t posted in a long time mostly because I’ve been spending the majority of the last month devouring Houdini tutorials on the internet. Houdini is capable of handling incredibly complex visual effects, and its node-based architecture makes it ideal for effects R&D… if you can get past the learning curve. I’ve never seen a more complicated-looking program. Anyways, after beating my head against the wall for the better part of a month I’ve finally started making sense out of this program, and I want to share an effect I’ve been researching for an upcoming spot, and turn this into a sort of tutorial for dealing with particle systems, creating objects on the fly, and manipulating shapes using audio. Later on I’ll also go over how to make the effect into a “digital asset,” meaning packaging the effect into a single node with its own interface that you can then use for other shots or share with other artists. I really dislike video tutorials so I’m going to try to write this one out.

NSA02 | CHOPs Projects Lesson 2 | CHOPs ProjectsPublished: Oct 4, 2013 for Houdini 12.5 This week we continue learning CHOPs by doing a couple of projects. Specifically we will learn how to create the “Pin Table” effect in the original X-Men Movie. We will then move on and learn about the Table CHOP to import tabular data and create a small project that uses the data to create a star field. The scene files for this lesson are available using the button at the top right just under the embedded video. Are you New to Houdini? If you are new to Houdini and would like to follow through these lessons, be sure to download the FREE Houdini Apprentice edition then go through the First Steps Intro lessons. Instructor | Ari Danesh Ari Danesh is a Visual FX artist and Interactive Designer with 12 years experience teaching at the University level.
Faites votre propre AUDIOGRAMME en ligne Repeat: do not start in the top third of the chart. How to use this web service to measure equal loudness curves. Minimise any background noise: turn off machinery, close windows etc. What does your hearing curve mean? Most people will find that their hearing is most sensitive around 1–4 kHz and that it is less sensitive at high and low frequencies. How does your hearing response depend on loudness? The shape of your hearing response curve probably depends on loudness. Can you use this web service to measure hearing threshold curves? It is possible, but not likely. If so, the method would be to find the lowest sound level audible at each frequency. Under normal conditions, if you seek the lowest sound level you can hear at each frequency, what you will find is the lowest level of a sine wave that is not masked by the background noise that you are hearing inside your headphones. What do levels on the measured curve mean? Calibration and improvements. Related pages
Experiment with Musical Water Glasses > Virtual Learning Connections | A Virtual School Blog by Connections Academy Learning to read music can improve your math skills. But can music help you learn science, too? Sure, it can! Here is a fun and scientific music activity you can do with your child at home. Although this activity is simple, it’s a great way to exercise your student’s science skills and musical abilities. Here are some things your child can learn how to do in this activity: Use measuring cups (and fractions) Create secondary colors from primary colors with food coloring Understand and manipulate sound waves Experiment with new concepts Play different songs on the scale Below is the Musical Water Glasses Instructographic explaining each step of the activity. Here are some additional Musical Water Glasses activities to try: Fill the glasses by increments of ¼ cup. Fun Fact: Did you know that sound travels about four to five times faster in water than in air? What else can you do with Musical Water Glasses?
SOUND / Generating Sound with Houdini Above is how you might create a very simple SOUND in Houdini. Make sure that you set it to real time and then set the Audio Panel. I guess it is time to revisit this book by Andrew Lowell.... Creating, triggering and doing something with sound in Houdini seems to be something I have to explore further. In one way, it feels like a huge detour from Houdini and VFX, but on the other hand, it is kind of a revelation as well. MAX AND CHUCK Someone also mentioned about Max not long ago, a node based system similar to Houdini to generate sound and trigger things. Accidentally, I am currently doing this online course from Coursera:Introduction to Programming for Musicians and Digital Artists with Ajay Kapur. Above is a very interesting course where they try to mix sound and programming. I have to mention that only this year that I have been dedicating myself to learn programming and finally got it.
Good Vibrations From the honking of cars to music blaring out of someone's bedroom window, the world around us is saturated with sound. But what exactly is sound, and how do we hear it?

It's finally possible to see the movement of guitar strings in real time | Sciencedump When cameras try to capture guitar strings being played, they see wavelength-type movements from each string. This is pretty awesome, but it can only be seen on camera all due to the camera’s rolling shutter effect. The wild wiggly effect is totally invisible to the naked eye, but not anymore! The Wobble Strings project is able to recreate a camera’s rolling shutter effect for the human eye in real time through a sweep line projection. To pull this off they let the speed of the sweep line control in accordance with the pitch of the strings. Pretty clever right! To learn more about how they created this amazing Wobble String projector, be sure to watch the video below!
