GitHub Pages

• GitHub allows only one free hosting static page against per github account
• developers can develop their page with HTML, CSS, and Javascript.
• very important: for this your github account name, and newly created repository name must me the same. For example, if your github account is sample-git, then your page name must be sample-git.github.io, which later will generate url https://sample-git.github.io
• you can not push files to your repository, upload templates, or develop manually.
• https://jekyllthemes.io/ is an awesome repository for templates.

• OptiX is since 2009, real time ray tracing API based on CUDA. Good for intensive complex scene and rendering is fast.
• DXR and VKR are more for real time applications like games. However, DXR is on Windows and X-box. Great API for windows
• Vulkan works on windows and linux.
