Ray tracing is not really a new technology, but because of the real-time calculation of the emission of all light 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 large to be able to catch up anyway.
In fact, the graphics industry has not given up its ray tracing efforts and now it has set off a new wave of climax.
At the GDC conference in March, Microsoft announced the introduction of DirectX Raytracing in DX12. The two major graphics card vendors, AMD ProRender rendering engine, and Radeon GPU analyzer all began to introduce ray tracing. NVIDIA released GameWokrs RTX technology, but only the latest ones. Volta architecture, which is Titan V.
However, turning on real-time ray tracing without the local support of the N card is still very much a resource.
Disney uploaded a video on the tubing to demonstrate the effect of the “Star Wars Flight Simulator” after the light was turned on. However, in order to enable 4K resolution at the same time, the platform eventually used 8 NVIDIA Quadro P6000 graphics cards for graphics and physics calculations. .
The Quadro P6000 is based on the Pascal architecture, so it uses DX12's DXR for ray tracing. In the United States and Asia, the price of a single card on the P6000 is $4,700, and eight cards require $37,600 (approximately 236,800). .
