Default raycasted scene that consists of 1000 spheres (each with different kd, ks, ka and alpha parameters) and 200 sources of lights (each with diferent colors as well).
This project contains the source code for basic 3D ray caster of spheres with Phong reflection model.
Implementation was based on Ray Tracing in One Weekend series and Accelerated Ray Tracing in One Weekend in CUDA from NVIDIA's Developer Blog.
Following dependencies were used in this project:
- CUDA SDK 10.1
- OpenGL 4.6.0
- GNU Make 4.2.1
Change the current directory to the sample directory you wish to build, and run make:
$ cd sphere-raycasting
$ make
After succesfull compilation you should be able to run the program by simply calling:
$ ./cudarc
By default program will perform a pararell raycasting of scene with 1000 spheres and 200 light sources. If you want to specify certain parameters you need to add command-line arguments. For example command below will run a simulation of raycasting a scene with 2000 spheres and 300 light sources.
$ ./cudarc -s 2000 -l 300
It is possible to execute raycasting algorithm purely on CPU. In order to do so you need to add -cpu argument to your run command.
$ ./cudarc -cpu
When the program is running you can rotate the spheres by dragging mouse while lpm is pressed. If the mouse is dragged the same way but with shift pressed, rotation will apply only to sources of light.
