[1:36][Damage Assessment]
[2:37][We are trying to figure out how to finish off our world construction]
[4:23][Think about how to handle the ground]
[5:23][Look at how we're currently specifying the ground]
[6:49][Blackboard: Our system for defining the ground]
[10:36][Blackboard: A potential plan and guiding principals of engine architecture design]
[12:51][Blackboard: How to store the splat list]
[14:40][Blackboard: Figuring out the shape of the ground]
[17:24][Blackboard: Considering multiple Z-levels / depth]
[25:20][Blackboard: Empty space things will carve out regions like that]
[27:19][Blackboard: What are the splats for the region?]
[28:49][Try to make the ground plane scroll infinitely in all directions]
[29:39][Enlarge GroundBuffer, introducing MaximumZScale and GroundOverscan variables]
[35:25][Partition the GroundBuffer so that we can scroll it around]
[36:04][Blackboard: How the GroundBuffer is currently positioned]
[38:01][Locate GroundBufferP relative to CameraP]
[43:11][Plan to snap the GroundBuffer towards the camera's direction whenever it runs out of pixel coverage]
[43:33][Turn off the trees]
[44:48][Turn off Z doors]
[45:32][Turn on the trees]
[46:00][Make the ground constantly generate itself]
[47:08][Blackboard: Tiling considerations]
[48:38][Turn DrawTestGround into DrawGroundChunk]
[54:28][View the results in-game]
[55:08][Q&A][:speech]
[55:58][Q: Why don't we fill the entire game window instead of having all that black space?]
[58:29][Q: Are some of these issues with dealing with display on multiple levels stemming from the lack of a Z-coordinate for the camera to just do a lerp on?]
[1:01:03][Q: If no one's asking related questions, could you ballpark a time-frame when adding a font and text rendering system will become useful or necessary?]
[1:03:02][On learning C++]
[1:05:10][Q: You mentioned offloading ground drawing to a separate thread to prevent hitches. Is it possible to offload the drawing work over multiple frames, and would there be any benefits over either method?]
[1:06:30][Q: How much of a memory footprint is your game using already? Certainly it won't be large, but I'm more meaning how many different containers are there?]
[1:06:53][Q: Procedural generation of 2D graphics: is there some mainstream math for that?]
[1:07:38][Q: What is your programming experience as before Handmade Hero?]
[1:08:42][Q: How many different classes are you having to use already?]
[1:10:30][Q: Is there a simple way to explain pointers and references in C++?]
[1:16:30][Closing remarks][:speech]

Cinera 0.7.0 Update Add output parameter to all of hero/code, hero/intro-to-c and hero/misc, preserving the current URLs while allowing different .hmml filenames, notably for hero/misc which now gets sorted chronologically.

Relocate riscy and add newly converted hero The idea here is to reduce the amount of superfluous stuff downloaded to each server running cinera 2017-12-06 22:26:13 +00:00			`[1:36][Damage Assessment]`
