This branch contains source code for some 2.5D rendering functions written
for software rendering. The code needs a bit of cleaning up, but otherwise
should work fine. Pull requests are welcome to improve the code.
It will be kept in parity with the floordemo branch in SDL2TemplateCMake.
The code is written in mostly C such that students without a C++ background can more easily understand it. There are some parts that need to be overhauled, like the conversion from floating point coordinates to integer coordinates. However, the basic ideas should be evident. In class, we'll discuss how this would have been implemented using fixed-point arithmetic.
A live demo compiled using Emscripten and WebAssembly is available here
This template is intended for students in the COMP-3520 Introduction to Computer Graphics course at the University of Windsor, however it should serve as a useful template for anyone interested in getting started with the SDL2 library quickly on Windows using Visual Studio. It defaults to 64-bit executables with static linking only, which is ideal for learning purposes.
The following header files and precompiled static libraries are included:
Only Visual Studio 2017 with the v141 toolchain is supported at this time.
If this is a problem, just let me know by either creating an issue or sending me an email.
See my other repository for a CMake version of this repository that uses dynamic linking instead: SDL2TemplateCMake
This template allows you to get started right away after installing Visual Studio 2017.
Simply git clone this template onto your system, and open SDL2Template.sln in Visual Studio.
Next, build it and run the sample program.
You can use this as your starting point for all coursework.
Note that I don't require you to use Visual Studio 2017 for the course -- if you want to use Cygwin or MSYS2,
you certainly can. The instructions should be similar to what is in the Linux users section.
The sample code provided should display "Hello World!" in a window on your screen when run. You can clone this project as many times as you need for different assignments.
Students who know C++ are encouraged to use it, however, C++ is not a requirement for the course. The sample code provided is mostly C compatible for the benefit of students who haven't had much C++ exposure yet.
Static Code Analysis is enabled by default on Debug builds. If you see compiler warnings in your code, don't ignore them!
When we get to the more mathy parts of the course, if you have a good handle on C++, consider using Eigen for your Linear Algebra needs.
Although this template has everything you need to succeed in the course, in your own personal projects it's likely you'll want to go even further. Consider adding the following libraries for your arsenal:
- SDL2_image for easy image loading from a variety of formats
- SDL2_net for a basic cross-platform networking library
- SDL2_mixer for sound rendering
- SDL2_rtf for basic document handling (RTF)
If you find any problems with the template, please let me know by either creating an Issue on the project page or sending me an email.
