Add the following snippet to your HTML:. Like the look and feel of vintage radio, but want Pandora, internet radio and your own music? This project is for you! Read up about this project on. I used to love playing around with my Dad's big 's Zenith radio, tuning in to stations across America and around the world. The charm of that old Zenith stuck with me across the years: that beautiful dial, the tactile connection to those tuning knobs.

Zenith was the king of "User Interfaces" back then. These days, I like to follow others who have vintage radio projects BIG shout out to Tinkernut, here and youtube and longed to make a retro radio just for me - to recreate those good old times.

I researched quite a few old radios. Many, like "Cathedral" radios, were very cool looking, but could be hard to model in 3D, print and assemble. Finally, I settled on the classic Zenith "Cube" 5R model. I wasn't trying to faithfully replicate the 5R I just wanted something that would suggest the look and feel of it. There's a significant amount of soldering to this project, some a little challenging.

The real work begins when assembling the components into the 3D printed case. If you have large hands you may have a struggle. If you have a larger build-platform 3D printer, I strongly recommend you scale up the box and face - but you'll have to keep the other dimensions the same.

I have noted "key contributors" in the Team section of this article. For the sake of brevity and clarity, I will present a short version of their work.

I will leave links to the original source material. Please take a few moments to explore and support their great work. When you're finished with this project, you'll have a working internet streaming radio that's powered by the popular Logitech Media Server LMS. You'll be able to tune in 5 or many more, with some minor code tweaks of your favorite Pandora channels, internet radio stations, or playlists, using the tuning knob.

The tuning knob will also let you select different screens: an art deco clock, or cover art for Now Playing. The other knob will turn the device on and off, and control volume.

If you want to use Pandora, you must have a paid account. The pi3d graphical software draws the radio dial and needle, as well as an art deco clock and Now Playing art.

When the tune knob turns the needle, its location based on degrees of a circle is looked up in a dictionary. The pylms software is a python wrapper for LMS commands. The tuning knob is also a push button. A long press triggers a screen change to the clock or Now Playing art, or back to the radio dial.

Pi3d displays the clock. The volume knob has a push button, too. See the Operations section below for more details.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again.

RunTests is a video of the standard tests, giving an idea of what pi3d does, also here's an excellent, self explanatory YouTube video made by Peter Farrell that covers much of the content of this ReadMe.

There's plenty of 3D code flying around for the Raspberry Pi, but much of it is rather complicated to understand and most of it can sit under the bonnet! The pi3d module runs on platforms other than the Raspberry Pi On Windows using pygame, on linux using the X server directly and on Android using python-for-android and runs with python 3 as well as 2. This makes it generally faster and opens up the world of shaders that allow effects such as normal and reflection maps, blurring and many others.

It has various demos of built-in shapes, landscapes, model loading, walk-about camera and much more! See the demos on github. This tank emulates how a WOT tank works. Uses realistic modelling in a TKwindow. Potentially useful for first person navigation. There are actually at least 50 demos showing a variety of ways of using pi3d with different levels of complexity. Installation tar. Total zipped download from github is c.

Older Raspberry Pi versions will run python applications using pi3d from the command line using the 'legacy' drivers but can also run using the new drivers so long as X11 server is running as with RPi4. Here's a list of commands that have definitely worked on a couple of fresh stretch or buster installs. Please take time to check out the paragraphs below even if you use either of these quick start recipes The long list of dependencies 3rd apt-get line may take a while to run as well as the install Pillow.

Both will create hundreds of lines of messages:. There are various possibilities depending on the machine, what's already installed and whether you want to work with some of the latest additions. If you have pip installed you should be able to open a terminal and use pip3 install as above. If you might want to use features being added in the develop branch i.

But to pick up this version of pi3d you will need tell python where to look. Basically it just does sys. Although most demos work on 64MB of memory, you are strongly advised to have a MB of graphics memory split, especially for full-screen 3D graphics.

In the latest Raspbian build you need to either choose the GUI setup, run sudo raspi-config or edit the config. Before trying any of the demos or pi3d, you need the Python Imaging Library as this is needed for importing any graphics used by pi3d though see the minimal example below, which doesn't! The better equivalent replacement is Pillow. As of raspbian jessie Pillow is the default imaging library. It's already installed on the fully featured SD image, but it's left off the lite image it can be installed using the debian package manager for lite image you also need sudo apt-get install python3-numpy :.

If you miss any of the dependent libraries and need to add them later you will have to pip3 uninstall then re pip3 install. Setting up in a Linux environment is most similar to the procedure for the Raspberry Pi. Linux can be set up in its own boot partition or in vmware eg Player which is free, you will also need to enable 3d acceleration. Which should install mesa versions of libEGL.

Apparently LinuxMint does work. This provides coordinates of the pointer position relative to the window so limits movement for steering as used in the demos.

The installation of PIL or Pillow should be the same as for the Raspberry Pi above but you are more likely to need to manually install python3-numpy. It is likely that pi3d will run on OSX but you might have to compile your own mesa libraries though some seem to be available Pi3d has been run successfully in vmware on mac.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Aug 25, Nov 14, May 29, Jul 23, We will be running Raspbian Lite which is a free operating system based on Debian Linux and optimized for the Pi. Here we go:. Also, you will find a diagram of the Pi 2 here the Pi 3 looks very similar. These diagrams may help you in this section. Here are the steps:. We are ultimately creating a Raspberry Pi system that can run in headless mode i. It is possible to even complete the initial setup without a monitor and keyboard.

See this article for more information. See here for more details. Thanks to Graham Smith who pointed out this option in the comments! After connecting the power cord and booting, you will need to find the Raspberry Pi on your network so you can remote in using ssh. Use the ping command to locate your system on the network.

The following may work:. Later in this tutorial, we install Samba so finding your Pi on the network will no longer be a concern. We first need to make a few changes to the Pi for optimization, and to personalize it for our use. To get started, run the following command:. At this screen, we will configure our Pi. To navigate, there are a few keyboard shortcuts we need to know:.

Arrow down to Wi-fi and hit Enter. The Raspberry Pi is the brilliant brainchild from our friends in the UK. If you are not from the UK, some of the keys on your keyboard may not work as expected. Here are the changes I made to make my Pi feel at home in San Diego:. Change locale — hit Enter the screen will momentarily blip to black before returning to raspi-config. We want to enable the SSH server so we can remote into our system without dedicating a monitor, keyboard, and mouse to it.

Back at the raspi-config main menu, arrow down to Advanced Options and hit the Enter key. The Pi will then let you know that it needs to reboot to activate the changes you made. Reboot it now and log back in.What I type up there is a pseudo code: not the actual code.

More explanation; Let's say i have two textures 2 images bind as textures overlap each other. The problem I am facing is distinguishing The sampler data types in GLSL reference the texture unit, not a texture object.

By default, uniforms will be initialized to 0, so if you don't set the sampler uniforms, they will sample from texture unit 0 which is also the default unit. In your ProgramManager::LoadTexture method, you bind the And you need the viewing vector in the same space than It had to do with the fact that as PointLight and SpotLight were derived from DirectionalLight, they the PointLight and SpotLight objects would get casted to their base class, removing their "special attributes" and when I would do light.

I solved it by Sadly, it turned out that "not writing into one of the render targets" is undocumented behavior in opengl. In order to fix Not all GPUs use the same instruction set. Having only the binary on disk means that the sets of GPU architectures that can be used with that software will be fixed forever. If your objective is to achieve same result for front and backfaces of same gemetry and normals. You need to flip normal in shader in case triangles are in opposite direction than normals were calculated for them.

Usually that's consecutive groups of 32 or 64 threads.

The execution time of a warp is the maximum of the execution time of all threads within that warp. So if your early exit can make a whole warp terminate sooner The way, how you have implemented subsurface scattering effect is very rough. It is hard to achieve nice result using so simple approach. Staying within selected approach, I would recommend you the following things: Take into account distance to the light source accordingly to the inverse square law.

This applies No, you cannot draw to different framebuffers at the same time. But you can draw to different draw buffers atteched to a framebuffer. This is possible and called multiple render targets. It sounds like the API you are using does not offer you the possibility to use bool and int as Uniforms. The solution of using floats to circumvent this seems to be a good idea.

In your example, the problem you are having is because, unlike C and java, the Blurred small-res textures don't seem blurred enough. I think there is somewhere a problem regarding the width of the filter not number of samples, but distance between samples or framebuffer size.

Let's say that you have x original fbo, a a 15x15 downscaled version for bloom. And that you use The idea is still the same, but the API looks quite different. Let me try to explain this to you with my limited It's not at all a webgl question, but you can load the code with a XMLHttpRequest but only if you start a local dev server.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

A free Display gives the highest frame rate, but it will also consume more CPU, to the detriment of other threads or other programs. There is also the significant drawback that the framerate will fluctuate as the numbers of CPU cycles consumed per loop, resulting in jerky motion and animations.

A framed Display has a consistent if smaller number of frames, and also allows for potentially much smoother motion and animation. The ability to throttle down the number of frames to conserve CPU cycles is essential for programs with other important threads like audio.
