Turns out I can emulate a raspberry pi in software using QEMU. QEMU is not for the faint of heart, because it’s all command line and you have to start on a Linux system. Should I have splurged for the UTM Mac app? Probably. But if you’re going to do this, here are useful links.
So many things about Houdini can trip you up, then eat your face off while you’re down. Today’s example is the VEX dot operator. I haven’t ridden the VEX horse into battle in a very, very long time, and like any horse, if you’re not paying attention, it’ll do what it wants, not what you want.
I’m a visual person. I see stuff and make choices based on that. So what I see in Houdini’s Geometry Spreadsheet are columns with headers like this:
P[x] P[y] P[z] direction direction  distance
I’m getting reacquainted with Houdini of late, and getting back to grips with Houdini Digital Assets. these are encapsulated chunks of pipeline that support all manner of neat stuff, and they’re usually full of Python scripts that do interesting things with whatever’s going into and out of them. But they can have some glitchy behavior.
One that’s now bitten me in the ass twice (6 years apart) is the fact that the HDA’s Python Module has no idea where the hell it is. It doesn’t know where it’s instantiated and it doesn’t know anything about what’s attached to it, or … Read the rest
Eventually, I’ll need to upgrade my dev workstation from the 4-core Intel Core i5 I have now to something a little speedier and beefier. Unreal Engine 4 likes to recompile its shader library often enough that it slows me down, and building for multiple platforms can take its toll as well.
I think I’m going to go AMD this round, probably a 12 or 16 core Threadripper, and in my poking around, I found this article by Sebastian Aaltonen, founder of Second Order Games and formerly a lead rendering engineer at Ubisoft.
So a thing happened over the weekend. My scheme to mash up spatial computing and DJing became real. Here’s a clip:
So what’s happening here is this: The earlier Raspberry Pi with AudioInjector HAT now has a twin, with a cloned SD card of the first one.
There is a Pyle 444 preamp on each one:
This is necessary to unwrap the RIAA curve from the turntable signal and turn it into line level, which is what the Audioinjector HAT needs. In order to cure the abysmal latency brought on by the import process over X11, a single-deck instance of … Read the rest
