Made by: alexandre.dias

Usage: SCENE.obj OUTPUT.bmp [RENDER_OPTIONS] [NOISE_OPTIONS] [OPTIONS]

Features:

Multi-threading

Anti-Aliasing

Procedural Textures

Render Options:

--shaded (render the object with it's material colors)

--normals (render the normals of the object)

--distances (render the image in grayscale based on the distances to the
camera)

--procedural1 (render a procedural texture based only on coordinates
and discarding the normals. The image is in grayscale)


--procedural2 (render a procedural texture based on coordinates
and normals. The image is in grayscale)

--procedural3 (render a procedural texture based on coordinates
and normals. The image is colored)


default value: --shaded

Noise Options: (usefull only when using --procedural[1-3])

Classic : (well known fonctions)

--fbm (fractal brownian motion)

--warping (distorted fractal brownina motion)

--interference (fractal brownian motion with absolute value
to produce lines on the pattern)

Custom : (made be me using fbm and warping)

--ribbon

--galaxy

--galaxy-distorted

--pastel

--hypnotic

default value: --fbm

Options:

--th | --multi-threading (Enable multi threading)
default value: off

--anti-aliasing | --AA (Enable anti aliasing)
default value: off

--abs
default value: off

Multi-threading: --th | --multi-threading

When activated, instead of rendering pixel per pixel, send a line to be
rendered with pthread_create, once the maximum number of thread chosen
has been atteined, pthread_join all of them and repeat until all the lines
are drawn

render_pixel.c:
    contains the functions that render the image,
    with their multi-threaded variant

render_struct.h:
    contains the definition of the struct passed to
    pthread_create

Anti-aliasing: --anti-aliasing | --AA

When activated, instead of sending only one ray per pixel, 4 rays are sent
The color is averaged from those 4 rays

pixel_color.c:
    contains the function calling the 4 rays and averaging the colors of
    pixels

render_mode.c:
    contains the different functions for rendering the rays (distances,
    normals, perlin ...)

Procedural Textures: --procedural[1-3] and all the Noise options

Procedural textures using a perlin noise with a function to alter
the noise.

perlin.c:
    contains the functions creating the perlin noise.

function_procedural.c:
    contains the functions altering the noise.

procedural.c:
    contains the functions for the different procedural
    patterns (--procedural[1-3])
