42 | ========= | ||||||||
43 | |||||||||
44 | This OpenGL canvas implementation tries to keep all render | ||||||||
45 | output as high-level as possible, i.e. geometry data and | ||||||||
46 | externally-provided bitmaps. Therefore, calls at the | ||||||||
47 | XCanvas-interfaces are not immediately transformed into colored | ||||||||
48 | pixel inside some GL buffer, but are retained simply with their | ||||||||
49 | call parameters. Only after XSpriteCanvas::updateScreen() has | ||||||||
50 | been called, this all gets transferred to the OpenGL subsystem | ||||||||
51 | and converted to a visible scene. The big advantage is, this | ||||||||
52 | makes sprite modifications practically zero-overhead, and saves | ||||||||
53 | a lot on texture memory (compared to the directx canvas, which | ||||||||
54 | immediately dumps every render call into a texture). | ||||||||
55 | |||||||||
56 | The drawback, of course, is that complex images churn a lot of | ||||||||
57 | GPU cycles on every re-rendering. | ||||||||
58 | |||||||||
59 | For the while, I'll be using immediate mode, i.e. transfer data | ||||||||
60 | over and over again to the OpenGL subsystem. Alternatively, | ||||||||
61 | there are display lists, which at least keep the data on the | ||||||||
62 | server, or even better, vertex buffers, which copy geometry | ||||||||
63 | data over en bloc. | ||||||||
64 | |||||||||
65 | Next todo: put polygon geometry into vertex buffer (LRU cache | ||||||||
66 | necessary?) - or, rather, buffer objects! prune entries older | ||||||||
67 | than one updateScreen() call) | ||||||||
