SIGGRAPH2018 Day 2

So today’s major coverage is two speeches, one is from Rob Bredow, VP of ILM. The other is form the CEO of NVIDIA.

Rob’s talk is the power of creative process. In which he talked about his experiences to be the first time VFX producer on the Star Wars movie: Solo.

He mentioned the people will have 3 different stages during the creative process:

  • Just start: when you want to be in the field.

During the beginning, people should do study. And try to build the things from other’s work. More like interdisciplinary study. It is easier to create something based on other stuff.

  • Know the theme: when you already know the tools and try to actively work in the field.


  • Lead: How to lead creative process.

During this stage, people need to first define the theme, which is the concept you try to follow. Make sure to work on this path before dive into the detail. He use the example on the solo film where he hope to go back to the classic 70’s film style. Hence the movie production explicitly uses rig for the hyper speed traveling set, and under water explosion, which relies on the real hardware (huge 180 degree LED screen, and 20 thousands fps camera) to get real lighting and “explosion never seen before”.

Then it is about learn on the constraint, so people can focus on the right thing. He mentioned how the roller coaster in Disney’s Animal Kingdom was created. From the beginning when it is not fit into the style. Then people visit Nepal and found the story of Yeti to build up the story about Everest and Yeti for the roller coster.

Third is simplify. Try to make the target simple. He mentioned about a shot in World War where a rig is jumped out during a crash scene, which may need retouching the scene to remove. However, no one actually knows what that is and people pay attention to the character’s face, so it is indeed not that important to spend extra time on removing in the film.

The third is about share. Rob mentioned on the start of ASWF, the academy software foundation, where the film industry first time try to organize their software together to share tools between companies.

The topic title.
ASWF actually starts with a lot of big names. I think to explore these repositories could also help new people to get into the business.









He also proposed his photo book he made during the Solo movie, I think this is a very good collection.


Nvidia’s special event is crazy to attract a lot of people. It is also my first time to see the CEO’s iconic gesture: hold the nvidia card on the stage. The event is basically the announcement of the next big thing since CUDA introduced in 2003. The Turing architecture, where Nvidia makes real-time ray tracing rendering possible.

10 Gig ray per second, mixed operation on GPU 16 TFLOPS and 16 TIPS, 500 Trillion tensor ops per second, 8K image decoder. This monster makes real time ray tracing possible. It dramatically reduce the time of physical based rendering for movie quality images, hence could be very attractive to the movie industry. And since the basic version is not that expensive ($2300, I think it is worthy than some AR glasses), we may expect soon game developer may not need to play too much tricks on the shading effect while just let things following the physics law.

Mr. Huang really enjoys to use the high glossy RTX card to play with the audience.
Demo on the real time ray tracing Star Wars shot. The light does look real!
Introduce how different hardware/software stack it is for the new arch.
