First, the base address retrieved through GetPixBaseAddr or - read directly from the PixMap structure can become invalid anytime - memory is allocated in VRAM. This can occur either by explicit - allocations, such as calls to NewGWorld, or by implicit ones, such as - those associated with the internal texture allocation of OpenGL. The - stored pixel images themselves will still be valid but may have been - moved in VRAM, thus rendering any stored base addresses invalid. - You should never store an image's base address for longer than is - necessary and especially never across calls to NewGWorld or - texture-creation routines. - - Secondly, an offscreen pixel image allocated in VRAM can be - purged at system task time by the display driver. This means any - time your application yields time such by calling WaitNextEvent or - SystemTask you can lose your VRAM GWorld contents. While this - happens infrequently, usually associated with display resolution or - pixel depth changes you must code for this eventuality. This purge - can occur whether or not the GWorld is locked or not. A return value - of false from LockPixels, a NULL return value from GetPixBaseAddr - or NULL in the baseAddr field of the PixMap mean that the pixel - image has been purged. To reallocate it you can either call - UpdateGWorld or Dispose your current GWorld through - DisposeGWorld and reallocate it via NewGWorld. Either way you must - then rebuild the pixel image. - ------------------------------------------------------------------------------------- - - Currently, I don't account for (1). In my testing, NewGWorld never invalidated - other existing GWorlds in VRAM. However, I do have protection for (2). - Namely, I am using GetOSEvent() instead of WaitNextEvent() so that there are no - context switches (the app hogs the CPU). Eventually a book-keeping system should - be coded to take care of (1) and (2). - ------------------------------------------------------------------------------------- - - System requirements (* denotes optional): - - 1. DrawSprocket 1.7.3 - 2. *MacOS 9 or later (but *not* Mac OS X) for hardware accelerated blit / fill - 3. *May also require certain graphics hardware for (2). I trust that all Apple OEM - hardware will work. Third party accelerators may work if they have QuickDraw - acceleration in the drivers and the drivers have been updated for OS 9. The current - Voodoo 3 drivers (1.0b12) do not work. - - Coding suggestions: - - 1. Use SDL_UpdateRects ! - - If no QuickDraw acceleration is present, double-buffered surfaces will use a back buffer - in System memory. I recommend you use SDL_UpdateRects with double-buffered surfaces - for best performance on these cards, since the overhead is nearly zero for VRAM back buffer. - - 2. Load most-resident surfaces first. - - If you fill up VRAM or AGP memory, there is no contingency for purging to make room for the next one. - Therefore, you should load the surfaces you plan to use the most frequently first. - Sooner or later, I will code LRU replacement to help this. - - TODO: - Some kind of posterized mode for resolutions < 640x480. - Window support / fullscreen toggle. - Figure out how much VRAM is available. Put in video->info->video_mem. - Track VRAM usage. - - BUGS: - I can't create a hardware surface the same size as the screen?! How to fix? - - - - COMPILE OPTIONS: - - DSP_TRY_CC_AND_AA - Define if you want to try HWA color-key and alpha blitters - HW color-key blitting gives substantial improvements, - but hw alpha is neck-and-neck with SDL's soft bitter. - - DSP_NO_SYNC_VBL - Define for HWA double-buffered surfaces: don't sync - pseudo-flip to monitor redraw. - - DSP_NO_SYNC_OPENGL - Define for OpenGL surfaces: don't sync buffer swap. Synching buffer - swap may result in reduced performance, but can eliminate some - tearing artifacts. - CHANGELOG: - 09/17/00 Lots of little tweaks. Build modelist in reverse order so largest contexts - list first. Compared various methods with ROM methods and fixed rez switch - crashing bug in GL Tron.
