apple sucks !!!

Yo! Thx for github.

Real time ray tracing is what we want,ray tracing is simple.

Idk why this is in my Rex but I like it

i thought i'd understand visually how it works but i guess i was wrong

Hmm why my .ppm file does not exist anywhere, please help

One thing I didn't understand which is why you made the direction vector of every ray constant (0,0,1), I think it must be calculated as the direction from the camera towards the pixel. I'm I right or wrong?

which sublime text theme is that?

RTX ON

If I wanted to create a for with a different image each a time how could I do that?

I ran the code in visual studio code and a ppm file "out.ppm" got generated. But it has nothing in it. It shows 0 bytes. Could you please tell what might be the error?

this is awesome

For all the Windows people, if you want to open the file with your default viewer like him, the command is "explorer picture.ppm". That is, you should be writing system("explorer picture.ppm") instead of system("open picture.ppm")

The R, G, and B components are usually in the range of 0 - 255 inclusive, so you should mod by 256, not 255.

This is very impressive. If you could make a video explaining line by line, that would be awseom

wait so we dont need images?

It's out of focus can't read it.

Thank you very much. Modified it slightly to print custom barcodes from 1s and 0s to a pbm file. Github is: Chrissavi :D

The process cannot access the file because it is being used by another process. in visual studio 2019

This is exactly what I was looking for! Thank you very much!

This content is gold!!!

О, спасибо (thank you)

"Lemme just feed this object into this shit ton of linear algebra"

How located coordinate axises? X-axis to viewer, Y-axis - right, Z-axis - up?

Exactly what I wanted, huge thanks!

if you do this code also show similar thing what is this man code: #include<iostream> using namespace std; int main() { system("1.png"); }

Shouldn't the ray origin be 0,0,0 and ray direction x,y,1 ?

how do you get to the bash?

You should do an ideal gas simulation

Which compiler are you using?

#include <fstream> using namespace std; const int width = 255, height = 255; int main () { ofstream img ("image.png"); img << "P3" << endl; img << width << " " << height << endl; img << "255" << endl; for (int y = 0; y < height; y++){ for (int x = 0; x < width; x++){ int r = x % 255; int g = y % 255; int b = y * x % 255; img << r << " " << g << " " << b << endl; } } system("open image.png"); return 0; }

Hey Marcus, i followed through the video but when i run it, it generates an O file which cant be opened on Win 10. I did it on Code::Blocks. Please help.

Eres ua bestia amigo :3 Wou justo yo buscando cosas sobre Ryatracong y tu pones este video. Perdon si no hablo ingles xd

Is quadtree faster? Did I understand correctly?

In case anyone is confused, he is using pure C++ with fstream library (file stream - useful for creating and working with files of all types) to create a .ppm (portable pixel map / a very inefficient and uncompressed image filetype) file containing information of a sort of "snapshot" created using ray tracing techniques. The console is not a renderer, so when you compile this code do not expect to print the image. The code compiles and generates the .ppm file from source, which you can view with something like gimp or photoshop or fileviewer or most text editors.

How would you go about making a bounding box? i cant figure it out for the life of me and all the other "tutorials" ive seen use much more complex and messier code making it hard for someone whos new to the whole raytracing thing to follow along and actually understand whats going on.

Remove the «system» call. It has nothing to do with creating the image and should have been left out. Save yourself the compiler error and remove it.

it says system is undefined and it wont work

This looks so good! Thanks for the tutorial...

if you dont comment whats the difference from simply read the completed code?

i *literally copied the code* and it didn't work....... **confused screaming**

Can it be used as background so that we can print statements on it

When calculating the discriminant, isn't the formula (-b +- sqrt(b^2 - 4ac))/2? If so, why do you not divide by two in Sphere::intersect?

Next time put some bg music! Overall nice vid.

With vector, you can make more complex images, with fun and calculations.

how much particle? why u use textfile as console? great work.
