rendering

问题 My question popped out while reading the tutorials on SDL2, on lazyfoo.net and the code is being copied from this page int main( int argc, char* args[] ) { //Start up SDL and create window if( !init() ) { printf( "Failed to initialize!\n" ); } else { //Load media if( !loadMedia() ) { printf( "Failed to load media!\n" ); } else { //Main loop flag bool quit = false; //Event handler SDL_Event e; //While application is running while( !quit ) { //Handle events on queue while( SDL_PollEvent( &e ) !

问题 I'm new to Metal. I'm rendering a SceneKit scene with Metal using this Apple sample code. TLDR; it calls the SCNRenderer's render function and passes in a command buffer. I'm compiling for Big Sur. It works, but it is not anti-aliased. I've tried a few ways to achieve it, as you can see in the updates below. Without Metal, I'd just set isJitteringEnabled to true on the SCNRenderer, and I get beautiful (and slow) 96-ish-pass renderings. If I try to do this with Metal, I get weird pixel format

问题 I need to create a unity project which runs in Headless mode (using the -batchmode command), but it must capture screenshots e.g. every one second and write them out to a file. I understand that in headless mode you need to forcefully call Camera.Render() in order for anything to be rendered. It seems that time freezes after the first screenshot is captured. The first screenshot looks absolutely correct, but all subsequent screenshots are identical to the first, implying that time has frozen.
