+# Design
+Manigraph is a program designed with sustainability in mind. It is built to be 
+portable, resource-efficient, and easy to maintain and scale. The program 
+follows a Data-Oriented Programming (DOP) paradigm, where each file is 
+responsible for a specific data type and manages its own dependencies. Each 
+function is named after the file it resides in, ensuring a clear organization
+and structure.
+
+The independence of data types allows for efficient scaling and maintenance. 
+The main file is a special case in this design: it is responsible for combining
+all the data types in a comprehensive manner, actng as the workflow of the program.
+
+# Contributing
+Before commiting use `clang-format`, for coding style consistency. Your 
+contribution must be whitin the design principles and the concept of Manigraph.
+
+The following diagram illustrates the relationships between files, showing how 
+they are connected through dependencies. It also highlights the scenarios where
+files are not independent of one another,

-# Estructura de archivos
-Díaz Camacho Pedro Emilio
-
-# Headers
-## main.h
-Este archivo incluye los prototipos internos, que va a usar el programa
-funge como api interna para los desarrolladores y debe estar bien documentada.
-
-# codigo fuente
-
-## main.c
-Este archivo debe configurar el programa antes de iniciarse, avisar de los problemas
-que eviten que el programa se ejecute correctamente, iniciar y terminar los objetos que use el
-programa, así como ejecutar la función principal
-### Depende de
-- <GL/gl.h>
-
-## context.c
-En este archivo se escoge un color para limpiar la pantalla y tiene una función para limpiar
-tanto lo dibujado en pantalla, como distintos buffers gráficos.
-### Depende de
-- <GL/gl.h>
-
-## input.c
-Incluye la función `poll_input`, que se ejecuta en cada ciclo del programa y devuelve un
-cuaternion de tipo `float *` que representa la rotación total del cubo, después de interactuar 
-con el programa.
-### Depende de
-- <GLFW/glfw3.h>
-- <cglm/quat.h>
-
-## matrix.c
-Incluye las funciónes para configurar y cargar en la GPU las 3 matrices principales.
-- `fix_matrix` esta matriz no cambia y se usa para configurar la perspectiva y la vista que
-va a usar el programa en todo momento.
-- `mdl_matrix` esta matriz depende de cada mesh y describe la rotación única de cada objeto,
-se usa para rotar los ejes ortogonamente con un indice.
-- `rot_matrix` esta matriz describe la rotación total de todos los objetos y se configura con
-un cuaternio
-### Depende de
-- <cglm/mat4.h>
-- <cglm/cam.h>
-- <cglm/quat.h>
-
-## mesh.c

-colección de triángulos que describen un objeto multidimensional.
-### Depende de
-- <GL/gl.h>
-- <stdlib.h>
-
-## shader.c
-Debe crear, destruir y usar los shaders, estos shaders son programas para la gpu escritos en glsl para
-además aquí se carga memoria en gpu con las funciónes `gload_`
-### Depende de
-- <GL/gl.h>
-
-## texture.c
-Debe cargar, usar y destruir las texturas, que va a usar la gpu,  también crea una textura 
-para una paleta de colores definida, esto para manipular fácilmente los colores que usará el programa.
-### Depende de
-- <GL/gl.h>
-
-## window.c
-Crea, usa, limpie y cierra una ventana, una ventana tiene un contexto de OpenGL asociado para poder
-dibujar objetos en ella, tiene una función especial para avisar si la ventana está abierta para
-dibujar.
-### Depende de
-- <GLFW/glfw3.h>
-
-# Datos
-## data/cube.h
-Aquí esta la información del mesh de un cubo, este se va a borrar cuando podamos
-importar meshes para graficarlos.
-
-## data/axis.h
-Aquí está el mesh de un solo eje, este se va a rotar para hacer los otros 2 ejes.
-
-## data/shaders.h
-Aquí estan los shaders en glsl para dibujar en pantalla

-# Tipos de datos del proyecto
-Díaz Camacho Pedro Emilio
-
-# Introducción
-En este archivo vamos a detallar los tipos de datos únicos del programa, estos
-tipos de datos son estructuras que representan objetos computacionales y son
-necesarios para integrar las distintas partes del programa.
-
-## window_t
-En `window.c` tenemos una estructura que es la ventana y esta se representa por `window_t`,
-este tipo de dato es un pointer que es manejado por `glfw`.
-
-## id_t
-`id_t` es un tipo de dato que representa objetos de `OpenGL`, estos datos
-normalmente vienen enumerados, y en `manigraph` se usan para representar `shaders`, 
-`programs` y `texture`.
-
-## mesh_t
-Este es un tipo de dato usado para interactuar con `mesh.c`, este representa la triangulación de un
-objeto gráfico y funciona ocultando las variables que `OpenGL` necesita en un `void *`.
-
-## mat4_t
-`mat4_t` se usará para representar las matrices, se usará este tipo de dato exclusivamente
-en `matrix.c` y funcionará con el tipo de dato `mat4` de `cglm`.
-
-## quat_t
-Este tipo de dato sirve para representar un quaternio, este quaternio representa la rotación
-del objeto gráficado en la proyección tridimensional, y se usará para crear una matriz que
-pueda entender `glsl`.
-
-## narray
-`narray` es un tipo de dato que funciona como un `array` enumerado, esto significa que el primer
-elemento del `array` dice cuantos elementos tiene este, sin contar el primer elemento, y los demas elementos 
-funcionan como un `array` normal. 
-
-esta estructura nos ayuda a trabajar con arrays de tamaños arbitrario de forma óptima y sin tener que marcar el
-último elemento de forma especial.
-
-### narray_u8_t
-es un `narray` para `char` y `unsigned char`.
-### narray_float_t
-es un `narray` para `float`.

-# Objetivos
-## Prioridad alta
-- [ ] El programa debe actualizarse cuando interactuan con el.
-- [ ] El usuario quiere:
-	- [X] Ver 3 ejes en todo momento.
-	- [ ] Ver que ejes esta viendo.
-	- [ ] Ver cuantos ejes hay.
-- [X] El usuario quiere:
-	- [X] Rotar estos ejes,
-	- [X] Ver donde quedan los ejes despues de la rotados.
-- [ ] El usuario experimentado quiere ejecutar el programa y pasar la variedad:
-	- [ ] Como argumento del programa.
-	- [ ] Desde la entrada estandar del programa.
-
-## Prioridad media
-
-- [ ] El usuario quiere:
-	- [ ] Cambiar los ejes que se ven por pares.
-	- [ ] Cambiar los ejes donde esta la informacion de los ejes.
-- [ ] El usuario quiere interactuar con el programa:
-	- [ ] Usando solo el mouse.
-	- [ ] Usando solo el teclado.
-
-## Prioridad baja
-- [ ] El usuario quiere guardar las transformaciones como un archivo GIF.
-

-# Problemas esperados al desarrollar
-Diaz Camacho Pedro Emilio
-
-## OpenGL esperan objetos tridimensionales, no de n dimensiones.
-
-Usando glVertexAttribPointer podemos pasar las coordenadas que 
-queramos de los puntos de las variedades, y con ello usar objetos 3D en
-el shader.
-
-## Rotar ejes por pares en una animacion continua.
-- Con glVertexAttribPointer podemos pasar las coordenadas del eje 
-seleccionado, al shader.
-- Con la funcion mix del shader y bloqueando el input, podemos hacer 
-una animacion pasando una variable con la cpu.
-- Cuando la animacion termine intercambiar los indices del layout, 
-usando glVertexAttribPointer otra vez.
-
-## Volumen de la variedad.
-Dado que la funcion parametrizadora es continua, mandamos la frontera
-de un n-cubo a la frontera de una variedad, por lo que solo basta 
-graficar la frontera de la variedad.

-# Manual de usario para Manigraph
-Manigraph es un graficador interactivo de variedades que lee archivos
-binarios de una variedad multidimensional y los proyecta a 3 dimensiones.
-
-# Glosario
-Llamaremos a los 3 ejes de la proyección tridimensional `X`, `Y` y `Z`,
-este sistema de coordenadas es derecho con el eje `Z` apuntando afuera de la pantalla
-
-# Controles
-## Teclado
-- `Q` Rota el eje `X` de forma horaria.
-- `W` Rota el eje `X` de forma antihoraria.
-- `A` Rota el eje `Y` de forma horaria.
-- `S` Rota el eje `Y` de forma antihoraria.
-- `Z` Rota el eje `Z` de forma horaria.
-- `X` Rota el eje `Z` de forma antihoraria.
-## Mouse
-- Hacer `click` en un eje lo selecciona.
-- El `scroll` del mouse hace girar al eje seleccionado.
