RayTracerV1

A Simple SDL Raytracer made in C++

To make it go

• Just run make
• You need an xwindow environment or the like
• The program was tested using vcxsrv from within WSL
• You can use xming in WSL2, you just need to add your IP to X0.hosts
• Should just run natively on Linux with SDL2 installed Requires SDL2 sudo apt-get install libsdl2-dev in Ubuntu or the like

Instructions

• Use main.cpp to create spheres and mess with lighting, an example is in place

Troubleshooting

Getting this error:

libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
malloc(): corrupted top size

or some equivalent? Run: sudo ldconfig -p | grep -i gl.so and look for any files on the right that have .1 on the end. If they exist, enter sudo mv </file/location/file_name.so>.1 </file/location/file_name.so>.1.ORIGINAL for example: sudo mv /lib/x86_64-linux-gnu/libGL.so.1 /lib/x86_64-linux-gnu/libGL.so.1.ORIGINAL
