Re: OpenGL Textures with SDL

Just for fun, I swapped the channels on a random image to complement my explanation. I was actually surprised I could do that with a image manipulation software (gimp). Here is the original and here is the swapped.

Re: OpenGL Textures with SDL

That is... strange. I'd say your image loading code (whether it's your own or a library) is loading the image data incorrectly, or at least in a strange way. If you are not familiar with how image data is stored, I recommend this recent video from computerphile . GL_BGR is basically the same as GL_R...

Re: Unreal 4 Engine is free

The source code, which was part of the subscription, is now free as well.

Re: OpenGL Textures with SDL

Not an opengl expert either, but you have to make sure to pass the right format to the glTexImage function. It all depends on the way you're loading the image data, but since you didn't mention that I can't help you much. Make sure you understand what the parameters are ( docs ) and check the docume...

owncloud

I just read estk devlog002 and saw this on the bottom: To my team: I'm compiling the new Windows build right now and will have it up on Owncloud within the next few minutes. Are you guys using owncloud? I am a big fan and user of the project myself. That's great! Yes, the post has been around for a ...

Re: Python threading SUCKS, Multiprocesses dont (as much)

I thought that was a known fact. Your explanation is almost true, but things are much messier than that. Your solution, though, was correct: just use multiple processes instead of multiple threads. Python's stdlib makes it relatively easy to move from one to the other. If you are really curious, thi...

Re: Dear Apple

I don't know about obj-c, but c rules are that types get promoted when two different types are compared. I don't have a reference right now, but one of the rules says a signed int gets promoted to an unsigned int. $ cat > test.c #include <stdio.h> int main() { printf("%d\n", (unsigned int)...

Re: Questions regarding qt

Not an authorative answer, but I'm pretty sure the lower levels of their environment (engine and libgyro) don't use qt. I don't remember if Falco mentioned it at some point or if I just concluded from the fact that it's a huge (unecessary) dependency to include. They use it on the rest of the tools,...

Re: C4Android

Not trying to lead the conversation astray, but on my android tablet I use a combination of vps/lan server + ssh + tmux + vim. I wonder how an android IDE deals with libraries such as sdl, which certainly aren't included on the os.
