🚨 WARNING: If you are a FRI student feel free to use this code to help yourself with your own (raytracing) project. But please do not copy the code or its segments, because plagiarism is taken very seriously at our faculty!
This is an implementation of raytracing in Matlab created during the Mathematical modeling course at Faculty of Computer and Information Science - University of Ljubljana.
Open the file test_raytracing.m with Matlab or Octave and hit the Run button or type test_raytracing in the console. A rendered image should appear on your screen in a few seconds.
Note: if you are using Octave it may take a lot more time to render the image.
You can change the image resolution by changing the variables image_width and image_height in test_raytracing.m.
You can use your own custom objects by changing the inline functions f, f1 and f2. Make sure
to also correctly change the corresponding partial derivatives (eg. dfdx, dfdy and dfdz), otherwise
the object may not render correctly.
Note: the defined functions should have an equation of the form f(x, y, z) = 0. Your custom
function definition in the code should then look like the following:
f = @(x, y, z) left_hand_side_of_the_equation
Here are two example renders. The first one features some generative colouring and the second one
has a reflective shader. You can find a few more examples in the images folder.
