Creating Lighting Textures — Handmade Hero — Episode Guide

0:03Recap and set the stage for the day with a few words on renderer programming

2:58Light probing

4:01Try to run the game, but be told that our Visual Studio Community 2013 license "has gone stale"

7:42Consider our options

9:54Check for a build of Milton for Linux¹

12:05Consider taking a poll

13:41Try putting in our credentials

17:43Run the game and note the problem imposed by the 2.5D world with respect to lighting

20:43Consider making a voxelisation pass in order to give us some usable geometry

23:10Blackboard: Looking up our lighting from a texture

26:53Blackboard: Extending this texture sampling into three dimensions

31:17Blackboard: Spherical harmonics and Fourier transform

38:04Blackboard: Lighting Equation

39:34handmade_opengl.cpp: Make CompilePeelComposite() not use the specular but only the diffuse coefficient, and run the game to see what that looks like

40:51Blackboard: Specular and Diffuse

44:01Blackboard: Reflections

49:48Blackboard: Texture encoding for the lighting

56:32handmade_opengl.h: Add lighting data to the open_gl struct

58:26handmade_platform.h: Enable DefaultRenderCommands() to set lighting settings

59:12handmade_opengl.cpp: Enable OpenGLChangeToSettings() to create a lighting framebuffer

1:02:40Consider the need for a different type of storage from the depth peels

1:04:41handmade_platform.h: Add lighting data to the game_render_settings struct

1:05:14handmade_opengl.cpp: Start to enable OpenGLChangeToSettings() to create a light texture

1:06:19handmade_platform.h: Specify that the lighting data in game_render_settings is a power of 2

1:06:56handmade_opengl.cpp: Finish enabling OpenGLChangeToSettings() to fully create a light texture

1:08:48Blackboard: Consider storing three directional and one intensity value

1:13:06hanmdade_opengl.cpp: Enable CreateFramebuffer() to handle floating point textures

1:14:55Run the game with a floating point depth buffer

1:16:09handmade_opengl.cpp: Try using GL_DEPTH_COMPONENT24 and run the game to see how that is

1:18:04handmade_opengl.cpp: Set up CompilePeelComposite() to handle our new lighting texture encoding

1:23:44Run the game to see the exact same thing

1:24:21handmade_opengl.cpp: Make CompilePeelComposite() produce coloured light

1:24:45Run the game to see that coloured light
