0:03Welcome back

1:18Promote 4coder and discuss modal editing

10:42Recap and set the stage for the day

12:48Blackboard: Texture Downloads

15:14Blackboard: Thinking of the GPU memory like a cache

18:46Blackboard: Swizzling

19:24"CBAD, that's my rapper name"^α

26:11Blackboard: Power of 2 textures and modern rectangular texture processing

29:12Blackboard: The problems with our current texture downloading scheme

33:59"Drivers and Windows. They conspire to "help" you"^β

34:05Blackboard: Asset stores

37:18Blackboard: How the CPU asset store works

38:52Blackboard: The GPU asset store

42:00handmade.cpp: Return to the codebase^γ

42:05handmade_opengl.cpp: How our loading currently happens

44:14handmade_asset.cpp: Refresh our memories as to what LoadBitmap and LoadAssetWorkDirectly do

49:10handmade_opengl.cpp: Move glTex* calls to handmade_asset.cpp and consider holding the frame if we are not ready with the texture

51:07win32_handmade.cpp: Pull the pieces of the picture together

54:02win32_handmade.cpp: Call Win32CreateOpenGLContextForWorkerThread in ThreadProc

55:44win32_handmade.cpp: Introduce Win32CreateOpenGLContextForWorkerThread

1:02:18win32_handmade.cpp: Introduce struct win32_thread_startup

1:04:31win32_handmade.cpp: Pass Startup to Win32MakeQueue directly

1:06:19win32_handmade.cpp: Undo and introduce GlobalOpenGLRC and GlobalDC instead

1:11:13Run the game and see nothing

1:12:02win32_handmade.cpp: Add bool32 NeedsOpenGL to platform_work_queue

1:16:02Run the game and still see nothing

1:16:39handmade_platform.h: Add platform_allocate_texture and platform_deallocate_texture to platform_api and add their equivalent calls

1:20:03handmade_asset.cpp: Call Platform.AllocateTexture in the FinalizeAsset_Bitmap case

1:26:30win32_handmade.cpp: Write PLATFORM_DEALLOCATE_TEXURE

1:28:01"The stream actually hasn't ended..."^δ

1:34:08handmade_asset.h: Add AssetType to asset_memory_header

1:39:56Run the game, see nothing and leave it at that

1:48:19ezysigh Is there a way to preload vertices / normals / colors to the card in the same way as textures (e.g. before glDrawElements is called) or is that usually never an issue?
