A little faculty project that implements a Raytracer which runs on the CPU.

The code is in C/C++.

Just launch a terminal in the root directory and run the make command.
Once done you can use the program with ./mrt [options].

Two parameters are needed to run the program.
First you need to provide an output file in which the render will be saved.
This can be done with the -filename option.

Then, you need to provide which scene you want to render.
This can be done with the -scenenumber parameter. The default value is 0.

Some options are available.

• width: Integer -> It sets the resulting iamge width.
• height: Integer -> It sets the resulting image height.
• aa: Integer -> The amount of Anti-aliasing for the render.
• aamode: String (none | luma | sobel) -> Which optimisation you want to apply to the anti-aliasing (see bellow).
• focaldist: Float -> The focal distance for the render.
• focalrange: Float -> The range within the render will be sharp.

This parameter can be sets to one of the following values : none, luma, sobel.

• none means that the anti-aliasing is just a basic superslamping.
• luma means that the objects edges are detected by their luminosity. The antialising will only be applied on them.
• sobel means that the render will be parsed with the sobel operator to detect edges and a superslamping will be done in these areas.
