Anyways since various people have done 3d graphics, I'm wondering if anybody can give me...

Are you really sure you want to do this ???? There are various side-effects you should consider, biggest of those being that each resource you include will add to the amount of memory required to start up the application. For example say the executable is 250kb, and you include 2mb of images, the ex...

Nice work. I've had a quick look whilst I was at work yesterday, and I must say the examples gave some insight into it abilities, hence making it standout for other libraries. I'll investigate this more once I finish my current project. Again nice work good to see more libararies added to the PSP co...

In SDL, you use ttf_render to create your text string and it returns an SDL surface to you. Once you have that surrface, you can reuse it as many times as you want. There is no need to re-create that surface again and again each time you re-pait your screen. I think you may have been doing that, th...

Hi Guys I checked and yes I was using 32 instead of 16, I changed this and well did not get the results I would have liked (night and day). But once I turned of the TTF handling, there was a dramatic improvement. I believe my TTF caching was not working as I expected it to, for some reason even thou...

Actually the problem occured as I was writing past the end of the first part of vram, and hence when the first vram buffer was being written (i.e second vram buffer displayed), the images would quite obviously bleed into the seocnd buffer and hence why it was flickering, only where i was overriding ...

Well I kept the SDL code around so i might go back to it. It is unlikely that the true type fonts were causing the problem, basically during initalisation all text was rendered to a surface, and those surfaces kept (cached) and simply blit'd to the screen later. Not sure if I was using 32 or 16 bit ...

Trying to draw anything complex, makes it run so slow it's a joke. Basically I've built a small windowing toolkit, including cursors, window, events, dialog, selec...

From experience, this type of behaviour is generally caused by memory overrun, and less commonly memory leak. Generally speaking if you have a piece of code writing into memory that it was not asigned then you may experience bad results but not always. For me this is generally a String related probl...

Has anybody had any experience with either of these IDE, and had much trouble setting them up....
