Introduction
This category is dedicated to 1K Intros for Windows 32.
Windows 1K Intros can be setup in C or Aseembler, or a combination of both, with only the few windows calls that are used being linked in. In general writing everything in assembler should give you a little more freedom in pushing/popping your function arguments but in th past quality intros have been written in both languages.
Graphics are usualy done using OpenGL+GLSL, but there are 1K intros out there that have used D3D instead.
Setup (OpenGL)
- ChangeDisplaySettings(&screenSettings, CDS_FULLSCREEN) - Initialise fullscreen view
- CreateWindow((LPCSTR)0xC018, 0, WS_POPUP | WS_VISIBLE | WS_MAXIMIZE, 0, 0, 0, 0, 0, 0, 0, 0) - Setting up a Maximised Window
- ShowCursor(NULL) - Hide mousecursor (usually required by compo rules
- GetDC() - Get DeviceContext handle
- ChoosePixelFormat(hDC, &pfd) - Set pixelformat describer by pfd to DeviceContext handle
- wglCreateContext(hDC) - Create OpenGL context
- Initialising GLSL Shader
- Mainloop that
