26 Implementation notes ----------------------------------------------------------------------
|
|
|
27
|
|
|
28 A bit on GWorlds in VRAM from technote 1182:
|
|
|
29
|
|
|
30 There are two important things to note about GWorld's allocated in
|
|
|
31 VRAM. First, the base address retrieved through GetPixBaseAddr or
|
|
|
32 read directly from the PixMap structure can become invalid anytime
|
|
|
33 memory is allocated in VRAM. This can occur either by explicit
|
|
|
34 allocations, such as calls to NewGWorld, or by implicit ones, such as
|
|
|
35 those associated with the internal texture allocation of OpenGL. The
|
|
|
36 stored pixel images themselves will still be valid but may have been
|
|
|
37 moved in VRAM, thus rendering any stored base addresses invalid.
|
|
|
38 You should never store an image's base address for longer than is
|
|
|
39 necessary and especially never across calls to NewGWorld or
|
|
|
40 texture-creation routines.
|
|
|
41
|
|
|
42 Secondly, an offscreen pixel image allocated in VRAM can be
|
|
|
43 purged at system task time by the display driver. This means any
|
|
|
44 time your application yields time such by calling WaitNextEvent or
|
|
|
45 SystemTask you can lose your VRAM GWorld contents. While this
|
|
|
46 happens infrequently, usually associated with display resolution or
|
|
|
47 pixel depth changes you must code for this eventuality. This purge
|
|
|
48 can occur whether or not the GWorld is locked or not. A return value
|
|
|
49 of false from LockPixels, a NULL return value from GetPixBaseAddr
|
|
|
50 or NULL in the baseAddr field of the PixMap mean that the pixel
|
|
|
51 image has been purged. To reallocate it you can either call
|
|
|
52 UpdateGWorld or Dispose your current GWorld through
|
|
|
53 DisposeGWorld and reallocate it via NewGWorld. Either way you must
|
|
|
54 then rebuild the pixel image.
|
|
|
55
|
|
|
56 ------------------------------------------------------------------------------------
|
|
|
57
|
|
|
58 Currently, I don't account for (1). In my testing, NewGWorld never invalidated
|
|
|
59 other existing GWorlds in VRAM. However, I do have protection for (2).
|
|
|
60 Namely, I am using GetOSEvent() instead of WaitNextEvent() so that there are no
|
|
|
61 context switches (the app hogs the CPU). Eventually a book-keeping system should
|
|
|
62 be coded to take care of (1) and (2).
|
|
|
63
|
|
|
64 ------------------------------------------------------------------------------------
|
|
|
65
|
|
|
66 System requirements (* denotes optional):
|
|
|
67
|
|
|
68 1. DrawSprocket 1.7.3
|
|
|
69 2. *MacOS 9 or later for hardware accelerated blit / fill
|
|
|
70 3. *May also require certain graphics hardware for (2). I trust that all Apple OEM
|
|
|
71 hardware will work. Third party accelerators may work if they have QuickDraw
|
|
|
72 acceleration in the drivers and the drivers have been updated for OS 9. The current
|
|
|
73 Voodoo 3 drivers (1.0b12) do not work.
|
|
|
74
|
|
|
75 Coding suggestions:
|
|
|
76
|
|
|
77 1. Use SDL_UpdateRects !
|
|
|
78
|
|
|
79 If no QuickDraw acceleration is present, double-buffered surfaces will use a back buffer
|
|
|
80 in System memory. I recommend you use SDL_UpdateRects with double-buffered surfaces
|
|
|
81 for best performance on these cards, since the overhead is nearly zero for VRAM back buffer.
|
|
|
82
|
|
|
83 2. Load most-resident surfaces first.
|
|
|
84
|
|
|
85 If you fill up VRAM or AGP memory, there is no contingency for purging to make room for the next one.
|
|
|
86 Therefore, you should load the surfaces you plan to use the most frequently first.
|
|
|
87 Sooner or later, I will code LRU replacement to help this.
|
|
|
88
|
|
|
89 TODO:
|
|
|
90 Some kind of posterized mode for resolutions < 640x480.
|
|
|
91 Window support / fullscreen toggle.
|
|
|
92 Figure out how much VRAM is available. Put in video->info->video_mem.
|
|
|
93 Track VRAM usage.
|
|
|
94
|
|
|
95 BUGS:
|
|
|
96 I can't create a hardware surface the same size as the screen?! How to fix?

100 COMPILE OPTIONS:
|
|
|
101
|
|
|
102 DSP_TRY_CC_AND_AA - Define if you want to try HWA color-key and alpha blitters
|
|
|
103 HW color-key blitting gives substantial improvements,
|
|
|
104 but hw alpha is neck-and-neck with SDL's soft bitter.
|
|
|
105
|
|
|
106 DSP_NO_SYNC_VBL - Define for HWA double-buffered surfaces: don't sync
|
|
|
107 pseudo-flip to monitor redraw.
|
|
|
108
|
|
|
109 DSP_NO_SYNC_OPENGL - Define for OpenGL surfaces: don't sync buffer swap. Synching buffer
|
|
|
110 swap may result in reduced performance, but can eliminate some
|
|
|
111 tearing artifacts.
|
|
|
112 CHANGELOG:
|
|
|
113 09/17/00 Lots of little tweaks. Build modelist in reverse order so largest contexts
|
|
|
114 list first. Compared various methods with ROM methods and fixed rez switch
|
|
|
115 crashing bug in GL Tron. (Woohoo!)
