Semi-real-time Ray tracer written in C++, only using base C libraries and Win32API for displaying to screen and keyboard input
- adding spheres to the scene
- give location in 3d space
- radius
- material
- 3 different materials for spheres
- matte
- metal
- glass
- moveable camera using keyboard inputs
- render in low-quality mode or high-quality mode
- ENV = Windows
- Compiler = g++ on msys2 MINGW64
- run make
- ./renderer
- space = re-render
- d move camera x position by 1
- a move camera x position by -1
- w move camera y lookat by 1
- s move camera y lookat by -1
- e move camera x lookat by 1
- q move camera x lookat by -1
- arrow up move camera y position by 1
- arrow down move camera y position by -1
- right arrow activates high graphics mode
- left arrow activates low graphics mode
*note after moving the camera position or changing mode press the space bar to re-render the image with the new settings
-
camera casts ray on each pixel in the viewport
-
ray is checked to see if it has made contact with any objects
-
color of the pixel is determined based on the normal vector of the ray and object
-
if no object is hit the color of the pixel is based on the background
- adding Quads instead of only spheres
- improving/optimizing the speed of rendering
- Bounding Volume Hierarchies
- Multithreaded rendering
- GPU hardware acceleration using OpenCL
- Light sources
- Code documentation
- FOV
- Starting position
- width
- aspect ratio
- pixel sample size
*note (higher value for width and pixel sample size = higher quality image but also slower rendering time)
