Accompanying drawing explanation
Fig. 1 is a kind of video memory control treatment embodiment of the method schematic flow sheet based on hardware-accelerated Rendering of the present invention.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with accompanying drawing.
Refer to Fig. 1, it is a kind of video memory control treatment embodiment of the method schematic flow sheet based on hardware-accelerated Rendering.
The invention provides a kind of video memory control treatment method based on hardware-accelerated Rendering, it comprises:
Step 1, input rendering objects;
Step 2, cutting is carried out to rendering objects; In the present embodiment, the method for rendering objects being carried out to cutting comprises: the display screen area of display divided by block, when rendering objects corresponds on this display screen, correspondingly carries out cutting by block;
Step 3, judge whether the rendering objects of present frame changes relative to the rendering objects of previous frame, if so, then perform step 4, otherwise, perform step 6;
Step 4, the rendering objects of cutting to be indicated, such as in the present embodiment, can the block at rendering objects place is all labeled as dirty;
Can understand like this, when the picture on certain block changes, also namely this region is dirty;
Step 5, the rendering objects of cutting is put into render-ahead queue;
Step 6, judge whether the rendering objects of cutting all carried out cutting, if so, then perform step 7, otherwise, perform step 2;
Step 7, judge the rendering objects whether having cutting in render-ahead queue, if so, then perform step 8, otherwise, perform step 11;
Step 8, search the texture playing up needs in the buffer, and judge whether to find, if so, then perform step 9, otherwise, perform step 10;
Step 9, the texture playing up needs found is sent into video card play up, then perform step 7;
Step 10, application play up the texture of needs, and copy buffer memory to, then perform step 9;
Whether step 11, determining program terminate, and if so, then perform step 12, otherwise, perform step 1;
Step 12, end.
A kind of above-mentioned video memory control treatment method based on hardware-accelerated Rendering, in the process realized, can adopt following technology:
1, pinup picture caching technology: when starting when playing, distributes the video memory page that a group is specified size in advance in video card, and the physical size of the pinup picture that the page can use according to game is split again, and such page just can place multiple pinup picture as required; In operational process, by certain strategy, aging replacement Treatment (as: least recently used algorithm) is carried out to the pinup picture in buffer memory.For each pinup picture entering buffer memory, needing to use some algorithm (as: hash etc.) to mark, required buffer memory pinup picture can be obtained by fast fetching from buffer memory when playing up, effectively avoiding data redundancy simultaneously.
2, the dirty rectangle technology of Hardware Render: first create slightly larger than a games window standby screen, then according to certain size by this standby screen piecemeal; During drafting, calculate institute's rendered object at the position of standby screen and this object block at standby screen, and carry out cutting according to the block belonging to it, the rendered object after cutting is joined successively and plays up in chained list; If the object of current drafting there occurs state change (as: position, animation are play frame etc. and changed) relative to previous frame, then, when drawing, need to notify that each piece belonging to this object is played up; After all objects needing to draw all cutting, traversal plays up chained list, search the object that all needs are played up, if the block residing for this object needs again to play up, then play up this object, otherwise do not play up, because the rendered object being cut into several part is continuous print playing up in chained list, during drafting, can play up needing the part changed to synthesize one batch, ensureing the efficiency played up.In addition, because the standby comparatively games window that shields slightly greatly, therefore when moving among a small circle, only needing the position adjusting viewport, without the need to redrawing whole standby screen, only having when viewport is beyond standby screen scope, just wiping standby screen, repaint all blocks.
