Ray tracing is not really a new technology, but because of the real-time calculation of the emission of all the rays in the picture, the refraction effect is extremely demanding on the hardware, and each frame of the movie is rendered for several hours.
So now GPUs use rasterized rendering technology, which is very efficient. However, the difference between light and shadow effects and real scenes is too big to catch up.
In fact, the graphics industry has not given up its ray tracing efforts and now it has set off a new wave of climax.
Microsoft announces the introduction of DX12 DirectX Raytracing , Open a new door for popularizing ray tracing.
Instead of tracking pure ray tracing, it's Most of the scenes still use the traditional raster rendering, a small part of the use of ray tracing, to enhance the shadow, reflection and other traditional techniques is difficult to perfect the effect.
Among the two major graphics card manufacturers, AMD ProRender rendering engine and Radeon GPU analyzer began to introduce ray tracing. NVIDIA released GameWokrs RTX technology, but only compatible with the latest Volta architecture, namely Titan V.
Of course, the support of the game industry is also essential. , EA Frost Engine, EA SEED R&D, Epic Unreal Engine, Unity Engine It has already been added for the first time, along with the benchmarking tool Futuremark 3DMark.
Now Futuremark has released a 3DMark switch ray tracing effect comparison demo, and announced that it will update 3DMark later this year and formally join ray tracing.
