2021年5月3日 · SDL provides some functions to help you ease the use of OpenGL, but you'll have to learn and use OpenGL to allow rendering 2D and 3D vector graphics. A good tutorial that I'd recommend on the basics of SDL is this site. It only has some chapters related to the use of OpenGL, but if you haven't used SDL much, this is a great start.

SDL isn't a 3D graphics engine. As is stated in its homepage: Simple DirectMedia Layer is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer.

2023年5月15日 · Be warned that the transition into 3D graphics from 2D is much more difficult than the transition into 2D graphics initially. It is much more important to understand the fundamental mathematics involved in 3D graphics, lest you end up breaking your code in ways that won't seem to obvious.

2023年6月6日 · DrawTriangle passes 3 points to SDL_RenderDrawLines. To draw a triangle, you have to draw 3 lines, and each line consists of 2 points, so total number of points in triangle is 6: To draw a triangle, you have to draw 3 lines, and each line consists of 2 points, so total number of points in triangle is 6:

2016年7月20日 · SDL and OPENGL are two different technologies so to speak. Also, this question will lead to opinions instead of facts Wikipedia says: Simple DirectMedia Layer (SDL) is a cross-platform software development library designed to provide a low level hardware abstraction layer to computer multimedia hardware components.

2020年10月28日 · When you want 3d graphics, then SDL doesn't give you much for that. So you will have to find a different solution for putting your 3d models onto the screen. But there is still some functionality of the SDL library besides graphics which can be useful for a 3d game which doesn't do its rendering through SDL: Loading and parsing asset files

2015年2月27日 · However, the documentation on SDL_GetWindowSurface says that it cannot be used for "3D or the rendering API on this window" source. Is there some other way to render 3D OpenGL 3.0+ in SDL 2.0, or should I just use SDL 1.2 because SDL 2.0 is only in Release Candidate status?

2012年11月5日 · I'm trying to make 3D sound with the SDL_Mixer lib by making a convolution of the audio stream with a HRTF (I'm using the MIT HRTF database respectively the mit_hrtf_lib based on the compact dataset). I register an effect with the callback function on MIX_CHANNEL_POST.

SDL is merely a platform abstraction layer, it substitutes neither OpenGL nor DirectX. When SDL is used though, it is more commonly used with OpenGL, since both cross platform libraries. Also worth noting is that SDL doesn't provide a widget toolkit, so if that's a requirement (not very common in fullscreen 3D games), something like Qt might be ...

2016年5月13日 · \$\begingroup\$ For the record, SDL and OpenGL aren't mutually exclusive. SDL is a "hardware abstraction layer" that also handles windows, events and input as opposed to being just a graphics library. SDL also has support to be used in conjunction with OpenGL so SDL can do all the non-graphics stuff while OpenGL handles the graphics.
