Minecraft SEUSPTGI is a very famous light and shadow package, known as the most eye-catching and strongest light and shadow in history. SEUS PTGI, another masterpiece (beta) of the famous SEUS light and shadow author Sonic Ethe, full name is "Sonic Ether's Unbelievable Shaders - Path Traced Global Illumination" (PTGI for short). This generation of light and shadow aims to use real-time calculation of light paths to achieve better and more accurate global lighting effects, and real-time calculation of light paths is part of the current cutting-edge concept - ray tracing.
Introduction to SEUSPTGI Light and Shadow
The operating method of PTGI is implemented using the familiar light and shadow plug-in OptiFine, which is implemented based on the OpenGL algorithm. It can be said that PTGI is implemented based on OpenGL. RTX is a patented technology of technology company Nvidia, and currently there are three ways to introduce it:
RTX Global Lighting - Subway: Departure
RTX Shadow - Tomb Raider: Shadow
RTX Reflection - Battlefield V
PTGI has nothing to do with these three technologies. Although PTGI and RTX are both technologies with the concept of ray tracing as the core, their respective implementation methods are different. In addition, RTX uses the RT core unique to the 20-series graphics card to optimize calculations, while PTGI performs calculations at the software level (OpenGL), so it has the characteristics that non-RTX20-series graphics cards can also run.
