[56:29][@pragmascrypt][Funny the pink didn't show up on the stream. OBS problem?]

|
|
[57:58][@garryjohanson][Curious if the CPU or the GPU actually communicates the information to the screen. I feel you mentioned this, but I forgot]
|
|
[59:01][@1213lac][What are your thoughts about Vulkan?]
|
|
[59:14][@sssmcgrath][If you're ever in the mood to do a straight-up unrelated tutorial stream, IO completion ports would be great cause I ain't reading about that ***]
|
|
[59:40][@ChaiLatteQuinoa][What do you think of Nvidia GE Force does not clear memory?]
|
|
[59:54][@elxenoaizd][Came in late. Do we have our own GL function pointers loaded now?]
|
|
[1:00:39][@insofaras][Try a color other than pink? OBS might treat that as transparent]
|
|
[1:01:09][@slashac][Do you know why they deprecate GL_ALPHA?]
|
|
[1:01:27][@Novynn][You don't need the DescribePixelFormat call, since when you use ChoosePixelFormat it modifies your DesiredPixelFormat with the correct stuff]
|
|
[1:02:17][@cubercaleb][Since we will have a depth buffer, does the Z-sort really matter anymore?]
|
|
[1:03:12][@Novynn][My bad! Looks like OpenGL docs are lying to me again]
|
|
[1:03:22][@Ikkir_Isth][Going to be doing multiple GL versions, or just the minimum for general Win XP machines? (What version are most of them even on anyway?)]
|
|
[1:04:08][@Snovind92][Would there be any benifit of using the new versions of OpenGL for a game like Handmade Hero?]
|
|
[1:04:30][@MadEqua][Is there a difference when calling a function (like glClear()) on the opengl32.lib vs the one on the graphics driver dll?]
|
|
[1:04:46][Blackboard: Code library vs Import library]
|
|
[1:06:36][@Quatzequatel][Since we are using OpenGL, will you be modifying our 2.5D'ness or keep the code as is?]
|
|
[1:06:49][@evraire][For ChoosePixelFormat() were we not supposed to specify iPixelType and set it to PFD_TYPE_RGBA?]
|
|
[1:07:27][win32_handmade.cpp: Set DesiredPixelFormat.iPixelType]
|
|
[1:08:14][@angus_holder][So by linking against opengl32.lib we don't need to use GetProcAddress at all with OpenGL?]
|
|
[1:08:56][Blackboard: Dynamic link table]
|
|
[1:14:56][@1213lac][Since you are complaining about windows pretty often, why don't you use another operating system?]
|
|
[1:15:48][@MrSlick1015][Do you think for the OS X port will you need a wrapper written in Objective-C to get use OpenGL and make a window?]
|
|
[1:16:20][@garryjohanson][This is probably dumb, but what about offloading much of the computing we are doing onto the GPU using OpenCL, then not use OpenGL and keep things mostly as is?]
|
|
[1:17:37][@cubercaleb][Over the break I wrote a program that generates OpenGL function pointer declarations and initialization by scanning cpp/h files to determine what needs to be added. Do you plan on doing something similar for Handmade Hero or will you keep it simple?]

[1:17:54][@slashac][How bad is an if statement in a shader?]
