générer des images de synthèse selon la méthode du Ray-Tracing. Ces images de synthèse représentent une scène, vue d’une position et d’un angle spécifiques, définie par des objets géométriques simples, entiers ou partiels, et disposant d’un système d’éclairage.
- Linux :
$ sudo apt install libsdl2-2.0-0 libsdl2-gfx-1.0-0 libsdl2-image-2.0-0 libsdl2-mixer-2.0-0 libsdl2-net-2.0-0 libsdl2-ttf-2.0-0
- Mac (takes time) :
$ brew install sdl2 sdl2_image sdl2_ttf
Then run :
$ make
Use make for compiling all files.
When you have already installed SDL2 library you can use this simple rules:
- make: Compile all.
- make clean: Delete temporary files.
- make fclean: Delete executable Rt file & libft.
- make re: It's rules - make fclean & make in one.
The programm takes a scene written in xml as an argument. Multiple scenes are directly available in the directory "./scenes2/" .
$ ./rt 'file_name'
- save flag
$ ./rt 'file_name' --save
[o | p]: Moving camera forward | Moving camera backward.[f | g]: stretch texture | stretch back texture.[h | j]: shift texture to right | shift texture to left.
- 4 objects : sphere, plane, cylinder, cone
- Multiple light sources
- Phong shading
- Shadows
- Translations & rotations (camera & objects)
- Each object can be cut on 3 different axes
- These 3 axes can be either the world axes or the object axes
- Translations & rotations are still working with cut objects
- Planes can either be cut into rectangles or circles
- Each object can have a texture put on it
- Variable scale & position
- Can use alpha channel to set the transparency of the object
- Can size the object (sets its limits)
- 24 bits & 32 bits images support
- Both have adjustable percentages
- Implementation of Snell-Descartes's indice of refraction
- A semi-transparent object has its colors projected in its shadow
- Checkerboard / rainbow
- hover effect
- Anti-aliasing
- Sepia & grey filters
- Stereoscopy
- blur
- cartoon
- Direct & parallel lights
- Colored lights
- multi lights
- ambient %
- Pixelation
- Multi-threading
