If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
367 * (X axis, Y axis and Z axis (with 3 axes)). ::SDL_HAPTIC_CARTESIAN
uses
368 * the first three \c dir parameters. The cardinal directions would
be:
369 * - North: 0,-1, 0
370 * - East: -1, 0, 0
371 * - South: 0, 1, 0
372 * - West: 1, 0, 0
typedef struct SDL_HapticDirection
{
Uint8 type; /**< The type of encoding. */
Uint16 dir[3]; /**< The encoded direction. */
} SDL_HapticDirection;
An unsigned int can't store negative values and I don't see an alternate way to
encode them in the docs or source. The best I have been able to come up with is
using a negative magnitude for the effect but this will only get me 2 of the 4
quadrants in the plane for 2d effects. I looked at the win32 and linux
implementations and I believe is is safe to use signed ints in the direction
struct. I am unfamiliar with the darwin haptics API so I don't know if it is
safe.

SDL on Sony Playstation3 ------------------------ Installation: First, you have to install the Cell SDK - Download the Cell SDK installer RPM and ISO images to a temporary directory such as /tmp/cellsdk. - Mount the image: mount -o loop CellSDK-Devel-Fedora_3.1.0.0.0.iso /tmp/cellsdk - Install the SDK installer: rpm -ivh cell-install-3.1.0-0.0.noarch.rpm - Install the SDK: cd /opt/cell && ./cellsdk --iso /tmp/cellsdkiso install You'll than need to install the SPU-libs - Run make ps3-libs && make ps3libs-install Finally, install SDL - Go to SDL-1.2/ and build SDL like any other GNU style package. e.g. - Build the configure-script with ./autogen.sh - Configure SDL for your needs: ./configure --enable-video-ps3 ... - Build and install it: make && make install Todo: - Mouse & Keyboard support - On SPU-side the current scaler and converter restrictions are: - resolution has to be a multiple of 8 (will work on that) - scaler/converter only supports the YV12 and IYUV format - the scaler works only bilinear (lanzos would be nice) - Optimize the SPU-program handling on the PPE side - Integrate spumedia in SDL Have fun!
