Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

Points of Interest
Instead of writing the results of the raytracing out to a .ppm file like in the original, the framebuffer data is pushed into an OpenGL texture:
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGB, GL_FLOAT, data);, this is easily presented by imgui: ImGui::Image((ImTextureID)texture_id, ImVec2(width, height));.
For clarity, and in order to keep the focus on ssloy's raytracing code, I've kept unrelated code away from tinyraytracer.cpp.
At the cost of an increased build time, all dependencies are built from source and statically linked to the final binary.
