Unprojecting Screen Boundaries | Handmade Hero Episode Guide

2:33Take a look at where we left off and where PixelsToMeters still happens

4:17Make the renderer responsible for telling us what the screen dimensions are

9:34Blackboard: Field of view in Y

12:10Put camera parameters in render_group

17:46Blackboard: Figuring out RawXY distance based on the ProjectedXY

18:56Calculate RawXY

21:50Figure out what we would fill in in terms of the ProjectedXY

26:26Step in and see what we're getting in terms of the size

29:41Check it out in-game

30:24Keep on the march of tightening this down

31:56Introduce MetersToPixels on the monitor

37:29TODO(casey): How do we want to control our ground chunk resolution?

38:03Pass DrawBuffer->Width and Height to AllocateRenderGroup and take a look in-game

38:47Refresh the FocalLength

41:55Massage the code

43:58Take a look in-game and introduce a way to verify the computations

47:22Draw the ScreenBounds

48:46Introduce the concept of a DebugCamera

53:53See it in-game

55:20Investigate why the entities aren't moving in and out of the SimRegion based on Y

56:51Draw the CameraBoundsInMeters, SimBounds and SimRegion->Bounds

57:49'Too Many Rects' by Casey Muratori^α

58:33Take a look at it all and start to investigate why entities are not getting pulled in up to the SimRegion->Bounds
