My own little Raytracer!
Generate images using the Raytracing protocol. Those computer generated images will each represent a scene, as seen from a specific angle and position, defined by simple geometric objects, and each with its own lighting system.
WHAT'S IN A .rt FILE?
- R(esolution) xRenderSize yRenderSize
- A(mbientLightning) ratio(0.0-1.0) R, G, B
- C(amera) x, y, z(coordinatesOfViewPoint) 0,0,1(3dNormalizedVector[-1,1]forEach x,y,z axis) FOV(0-180)
- l(ight) x, y, z(coordinatesOfLightPoint) Brightness[0.0-1.0] R, G, B
- sp(ere) x, y, z(coordinatesOfCenter) Diameter R, G, B
- pl(ane) x, y, z(coordinates) 0,0,1(3dNormalizedVector[-1,1]forEach x,y,z axis) R, G, B
- sq(uare) x, y, z(coordinatesOfCenter) 0,0,1(3dNormalizedVector[-1,1]forEach x,y,z axis) sideSize R, G, B
- cy(linder) x, y, z(coordinatesOfCenter) 0,0,1(3dNormalizedVector[-1,1]forEach x,y,z axis) diameter height R, G, B
- tr(iangle) x, y, z(coordinatesOfPoint1) x, y, z(coordinatesOfPoint2) x, y, z(coordinatesOfPoint3) R, G, B
(There's a few sample .rt files in the RT_FILES folder.)
KEYBINDINGS (on macOS) :
- any key = open snippet view !
- press 'end' = switch btw elements;
- c = camera1;
- v = camera2;
- 12 on top = light_size++ / light_size--;
- 12 on the right = object_size++ / object_size--;
- adws = translation control for obj && camera;
- arrows = rotation control for obj && camera;
- jlik = height and diameter augmentation/reduction;
- +- = camera or obj forward/backward;
- m = ambiant light
- rgbs = red/blue/green/sepia filter
- return = load image;
Prerequisite: have minilibx installed.
./miniRT rt_file.rt [-save to save image as .bmp]
