This sample program demonstrates DirectDraw animation using surface flipping.
Source: (SDK root)\Samples\Multimedia\DDraw\Src\Flip2d
Executable: (SDK root)\Samples\Multimedia\DDraw\Bin
The Flip2D program displays and animates a cube. You can change the screen mode by pressing the F10 key and selecting a resolution and color depth value from the Modes menu. Use the Cube menu or the keyboard shortcuts to increase (F7) or decrease (F8) the displayed size of the cube, or to switch to GDI drawing on the primary surface (F9).
Normally the cube is rendered on the back buffer and then the surface is flipped to the front. You can compare the results with those from rendering directly on to the front surface by choosing GDI drawing.
The palette that the Flip2D program uses for 8-bpp modes is red, green and blue wash. There isn't enough room in the palette for yellow, orange, and purple. In 8-bpp modes the Flip2D sample application maps yellow, orange and purple to red. If you select DrawWithGDI from the Cube menu, yellow, orange, purple are drawn without very many shades. This is because the program is using system colors, and there are only a few shades of yellow, orange, and purple available in the system palette.
