I am trying to render a colored square in OpenGL using glBegin(GL_QUADS) but for some reason it renders the square with an extra vertex in the middle. Screenshot. Am I doing something wrong or do I have to use a different method for 2d rendering?

I have a list of functions and values I'd like to put into a nested list. I'd like the result to be a LISP style list(something that looks close to some LISP style executable code) that I can easily process later. This list comes from a "sentence", that gets split into a list by word - it keeps defined phrases (multi word) together, by checking any multi-word tokens in the DB first, gluing them and then separating them later. Any words not in the database are ignored. Punctuation is also ignored. It just matches actual stored Tokens. This lets me write a sentence that can get translated into functions I can process later. We can ignore the fact that these are functions, and just think of them as strings, since that's how they're stored, but functions and arguments describe the use case perfectly, since that's what they are. Functions will be the first item in a list, followed by their arguments in the same list. A function with no arguments will be in a list with only that one element. An argument that is itself a function will be in a list(with it's arguments, if any). The number of arguments is each function takes is preset, and won't vary (it could call other functions that take their own arguments though). Should technically be able to go infinitely deep, though I'm sure a few levels will suffice if limiting helps. This is a recursive type problem so depth level shouldn't really matter. If it helps, I'm using Django, and so have access to any model methods there, since Token is a Model, as are the sentences.

I'm calling the list items "Tokens". They can be more than one word. They're actually stored in a database. Each Token can have: symbol, val, kind Symbol: Pretty format string to search for in sentence Value: The thing we want in the list Kind: An integer; number of args or code for other kinds

KIND_CHOICES = [ (0, 'Argless Function'), (1, '1-Arg Function'), (2, '2-Arg Function'), (3, '3-Arg Function'), (4, '4-Arg Function'), (6, 'Value'), (7, 'Ignore'), ]

Let's use these Tokens for an example: ("Symbol",'val',kind)

("Walk",'walk',1) ("To",'to',1) ("Sandwich Shop",'sandwich-shop',6) ("Order",'place_order',2) ("Toasted",'toast',1) ("Sandwich",'sandwich',6) ("Dine-In",'here',0) ("Eat",'eat',1) ("Back",'back',1) ("Home",'residence',6) ("Nap",'sleep',0) ("on the sofa",7)

Here's an example sentence: Walk To the Sandwich Shop, Order your favorite Toasted Sandwich for Dine-In, Eat your Sandwich, Walk Back Home, then finally Nap on the sofa.

The first list I'll end up with from my current working cleanup functions gives us: ['walk','to','sandwich-shop','place_order','toast','sandwich','here','eat','sandwich','walk','back','residence','sleep']

then, finally (the part I just can't get right! I'm off by one, get duplicates, missing tokens, or the wrong structure)

[['walk',['to','sandwich-shop']],['place_order',['toast','sandwich'],['here']],['eat','sandwich'],['walk',['back','residence']],['sleep']]

Some of my attempts have involved using a repeated placeholder string for the arguments, with various replace_or_append implementation attempts; inserting empty elements in a list for arguments, then using a put_in_next_empty_spot implementation(a few tries at that); and some simpler looping with an incremented index and pop. I'm just stuck on this for some reason and could use some brainpower on what seems like it should be a pretty simple problem to solve.

Here's some example code from one terribly failed attempt:

I am just trying to learn to draw 3d objects with pyopengl. The first thing I am trying to draw is the following code. The coordinates posat, i.e. the positon of atom is supposed to be a bcc lattice, but I am far from getting anything like a cube. The output is added. Kindly let me know what I am doing wring here:

I have texts that have been saved to a database without their formatting. I need to make them readable again. There are some clues to determine where paragraphs and titles used to be, but I'm stuck defining the correct pattern to wrap titles inside

Example of a text:

Amsterdam is trying reduce energy consumption from data centers.It's goals is to reduce consumption by 86 million kWh in the next three years.Current SituationToday all data centers combined use 460 million kWh every year

In above case, the title is Current Situation. I can detect the start of the title thanks to the punctuation and the end thanks to the uppercase letter of "Today" (that starts the next paragraph)

My regex works as follows:

• Matching group 1: start from punctuation
• Matching group 2: exclude more punctuation, continue until a lowercase letter ...
• Matching group 3: ...is directly followed by an uppercase letter

The Regex:

I'm currently trying to build Ammo.js on Windows, following the Instructions in the README. I have

• emcc in Path
• cmake installed via Visual Studio (C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe)
• MinGW installed via Chocolatey

Apparently, because I'm on Windows, cmake could not resolve any paths to the executables in CMakeLists.txt

How do I add an image as texture in my cube: I want to add my self-provided image as the surfaces of my cube while still having some lighting

I am using Visual Studio Code as my compiler

here is the code I copied:

Ive been on trying to do create some object on opengl and I have trouble with the objects some parts disappearance.

here my code. It is a default exapmle actually but I changed some parts

If one has a dict like the following:

I am attempting to make a 3D rotating torus with lighting. The rotating torus works fine. The lighting is the problem; if I leave GL_SPECULAR to its default, the light works fine. When I try to set it to a RGBA float quadruplet (what it is supposed to be) it says it is the incorrect format. I tried to print the actual default value of GL_SPECULAR using print(str(int(GL_SPECULAR))) it returns the float 4611.0, and I can not find any information on this type of color format. Here is my code:
