QUESTION
I am using the Panda3D wrapper for Python to run some 1st person game tests. I would like the collider of the ursina camera type called the FirstPersonController to extend its collider over the sprite. I have tried (without really knowing how as there aren't many tutorials on Ursina) using a BoxCollider() but I didn't really get how to do it. Can anyone help me?

Line:3 Import "sympy" couldn't be resolved
I have installed sympy using pip in my virtual environment. Why am I getting this error? When I run this code I am am getting the following error:
...ANSWER
Answered 2021-May-22 at 12:44The first step is to check whether you are running the code in the virtual environment, to verify that refer the below image
If you are not in a virtual environment that you have created just click that red box that I have marked in that pic and select the respective virtual environment Interpreter (python.exe).
QUESTION
I am working in a project where 3D visualizations are important to see what is happening during the setup stage and perhaps for visual validation by making a short videos of what is happening.
The problem that I have is that 3D visualizations in Python are too sophisticated, and complicated to learn for what I need. I find that Mathematica is the perfect kind of software...but it is not portable and is very expensive.
Question Is there any Python package similar to Mathematica?Clarification I don't want a "plotting" program, since plotting is not what I am looking for. I want to generate simple geometric shapes like spheres and cubes that can move around, this is more than enough. Give some coordinates, perhaps a rotation, and the program just shows the desired image(s) to export as a .png or make a quick video; as in Mathematica.
Packages like Pygame, Panda3D, Pyglet, etc., look too complicated and an overkill for what I need, as well as software like Blender, etc. Jupyter notebooks are similar, but they don't have the 3D graphics capabilities. I found a Python module named Fresnel, but it looks too sophisticated for what I need.
I have read several answers to this question here in Stack Overflow, but they seem outdated and not really what I am looking for. Further Clarification To draw spheres in Mathematica you do: ...
ANSWER
Answered 2021-Mar-17 at 09:40I know several other user-friendly plotting libraries than matplotlib, but not a lot provide an interactive view. There is of course the well known vtk but it's not for end-user
plotlyFor usage in a notebook, like jupyter and mathematica, you probably would go for plotly It's using a browser-based interface with plots very similar to mathematica
pymadcadIf you need a more offline version and what you are looking for is some view you can rotate/zoom/pan to look on your geometry by different sides, you can take a look at pymadcad It even works with touchscreens. It is not centered on 3D visualization, so it's a bit overkill to use it only for it, but for 3D curves, 3D surfaces, spheres and cubes as you said, it can do the job

So I tried converting a .blend file to .bam with blend2bam as suggested by the official Panda3D page but I am getting a FileNotFoundError. I am using Windows with Python3.7 (from the Panda3D install). I tried a lot of possibilities of how one could address the src and dst but it still did not work.

QUESTION
I'm creating a game in c++ with the Panda3D framework on Ubuntu. All of the Panda3D shared libraries are in /usr/lib/panda3d and all of the headers are in /usr/include/panda3d. I'm compiling with SCons, but I've tried it with gcc and it's the same, so here are the commands:
g++ -o src/main.o -c -fPIC -O2 -std=gnu++11 -I/usr/include/python2.7 -I/usr/include/panda3d -Iinclude src/main.cpp
g++ -o Test src/main.o -L/usr/lib/panda3d -lp3framework -lpanda -lpandafx -lpandaexpress -lpandabullet -lp3dtoolconfig -lp3dtool -lp3direct -lpthread
And here is the error I get when I run the executable:
./Test: error while loading shared libraries: libp3framework.so.1.11: cannot open shared object file: No such file or directory
There isn't much in the code, just initializing a Panda3D window, so I doubt that's the culprit.
As I said before, the libraries are in /usr/lib/panda3d, I've checked about a million times now and it's driving me crazy. I can't think of a single reason why I would get this error. Any help is appreciated :)
Edit:
I was looking through my files and there's a panda3d.conf file in /etc/ld.so.conf.d with one line: /usr/local/lib/x86_64-linux-gnu/panda3d. Does this have anything to do with it?
Edit #2:
I used the path in the above edit as the library path and got the same results, unfortunately.
...ANSWER
Answered 2019-Sep-30 at 05:17I can't think of a single reason why I would get this error.
The reason is very simple: the dynamic loader hasn't been told to look in /usr/lib/panda3d for shared libraries, and so doesn't.
You can run your program with:

I'm creating a launcher, and I have a combobox that has two items with specific functions/method calls, trying to have checks if one of the items is checked and to call a method if so.
I tried using the combobox currentTextChanged and currentIndexChanged methods, but I don't see any new results from using the method.

Answered 2019-Sep-05 at 19:27As mentioned in the comment, you need to connect the signals to a method that then performs some action. It seems like you're trying to call them instead and then use the return value, which won't work. Simplified example:
QUESTION
I'm working through some Panda3D tutorials and have created a few simple programs. At some point in the near future, I would like to be able to bundle my Panda3D program into a standalone application using PyInstaller.
However, I'm experiencing a strange issue even with the simplest program.
I've used the command pyinstaller -F -c -w 01\ –\ blank\ window.py.
It works as normal and creates a Unix executable and a macOS .app file in the dist folder. However, neither of them work, they just open and close immediately. After some research, I found the source of the problem.
When I run either executable from Terminal, I get this error:
...ANSWER
Answered 2019-Sep-02 at 08:49Generally pyinstaller find only with pip or anaconda installed package. Copying the panda3d module to the 01 – blank window.py direction solved the problem, how in the comment from AkThao described.
QUESTION
How can I get an integrated-graphics-accelerated headless X display running inside a Google Cloud Kubernetes Engine pod?
BackgroundI'm working on a reinforcement learning project that involves running a large number of simulated environments in parallel. I'm doing the simulations using Google Cloud Kubernetes Engine, with panda3d rendering to an Xvfb virtual display.
However, I've noticed that the simulation on my Macbook runs 2x faster than the one on Kubernetes, and profiling suggests the difference is entirely from drawing the frame. Other operations - like linear algebra - are at most 30% slower. My theory is this is because on my Macbook panda3d can take advantage of the integrated graphics, while Xvfb uses software rendering.
My suspicion - gathering together the info in the links below - is the trick is to get a hardware-accelerated headless X server running, then use Virtual GL to fork it across a second Xvfb display. But lord, I am way out of my depth here.
Uncertainties- Is hardware vs software rendering actually the source of my slowdown?
- Do Google Cloud instances have integrated graphics?
- Can a Kubernetes pod use integrated graphics without modifications to the host?
ANSWER
Answered 2019-May-30 at 13:47I will answer your questions in order :
Most likely yes but it is hard to determine for sure with the information you provided. It depends on how your software and the library you are using (panda3d) handle the rendering.
Google Cloud Compute Engine instances do not have integrated graphics, but you can always use GPUs (supported GPUs and related zones listed here). You can enable virtual displays on certain instances as explained in this document.
You can setup Kubernetes clusters or node pools in Google Cloud where the nodes are equipped with Nvidia GPUs as it is explained here.
You can take a look in here to check some examples on how to use Kubernetes with GPUs on Google Cloud Platform.
