good morning, afternoon or evening.
i was working with a for loop today and something seems to have gone very wrong as this is supposed to create a much larger file than it has
nx = 200
ny = 100
touch("image.PPM")
open("image.PPM", "w") do image
write(image,"P3\n" , string(nx) , " " , string(ny) , "\n" , string(255) , "\n")
for i in ny
for j in nx
r = i / ny
g = j / nx
b = 0.2
ir = string(Integer(round(255.99*r)))
write(image, ir , " ")
ig = string(Integer(round(255.99*g)))
write(image,ig , " ")
ib = string(Integer(round(255.99*b)))
write(image,ib , " ")
write(image, "\n")
end
end
end
this should output a ppm file of what is at the start of ray tracing in a weekend but i have not found any results other than a yellow pixel.
