|
|
[50:51][@chronaldragon][Q: Has this work fixed the normal map issue or will we need to address that specifically?]
|
|
[51:46][@tloch14][Do you think that making the Y component to be bottom-up will also help make sense of game mechanics like gravity?]
|
|
[52:34][@glasses_boy][Will we be implementing a matrix/affine transform in order to handle changes to coordinate systems?]
|
|
[53:01][Blackboard: Multiplying an incoming vector by a matrix]

[1:01:40][@pseudonym73][The mods had a lot of work to do today, just so you know]
|
|
[1:02:05][@stiegosaurus][Casey, maybe I missed it, but when will the Z ordering be done to visually correct sprites in front and behind the character?]
|
|
[1:02:41][@pseudonym73][It's more correct to call that the "translation part". The entire upper part is affine]
|
|
[1:05:17][@chochmah][When you exit the program, Visual Studio says that there are about 8 threads terminated. Is there more than one thread in Handmade Hero right now?]
|
|
[1:07:15][@cubercaleb][Would it be possible to have the renderer set up so the world curves back as you move along the Y-axis?]
