What do we do? Before we get started, just a quick self introduction about my background, I am a real-time rendering engineer at NVIDIA working on the RTX renderer in Omniverse. Before that, I was rendering functions are compiled More resources: https://gist.github.com/MattPD/9b55db49537a90545a90447392ad3aeb Before we dive into the system, I want to take 10 mins to have a quick recap about C++ coroutine and share expression into code. 1. Retreive awaiter & awaitable 2. Awaiting the awaiter(suspend and resume happens here) Awaitable & awaiter & co_await Useful to know • According to the definition, a type can

storing an int with value 7 ● Here we see ‘px’ again ● And we see an ‘asterisk’ before px ○ When an asterisk is before the variable name (and the type is a pointer), it means to retrieve the value at storing an int with value 7 ● Here we see ‘px’ again ● And we see an ‘asterisk’ before px ○ When an asterisk is before the variable name (and the type is a pointer), it means to retrieve the value at addresses (8/11) 36 ● Okay, so what happens with our pointer? ○ int x= 7; ○ int* px= &x; 7Visualizing Memory - Linear array of addresses (9/11) 37 ● Okay, so what happens with our pointer? ○ int x= 7;
