As the translation vertical array of described repetition geometric model make an addition to described summit packed array in；
The packed array signal generating unit of coordinate, for by the world coordinates matrix of described first geometric model, with time
After going through described drawing area, the described summit of generation is packed array is multiplied, and generates described coordinate packed array.
Device the most according to claim 9, it is characterised in that described models show positional information is also
Including: model index information；
Accordingly, described diagram parameter merges module, also includes:
Index packed array memory element, for being deposited by the described model index information of described first geometric model
Be stored in index packed array in, and record the packed array index quantity included of described index；
Side-play amount increases unit, if for there being the described translation vertical array of described repetition geometric model to add
In described summit is packed array, then by the index in the described model index information of described repetition geometric model
Value increases the side-play amount corresponding with described index quantity；
Index quantity updating block, for the described model by the described repetition geometric model after increase side-play amount
Index information make an addition to described index packed array in, and update the packed array index included of described index
Quantity；
Index packed array signal generating unit, be used for traveling through described drawing area, generate described index packed array.
11. devices according to claim 7, it is characterised in that described diagram parameter also includes: method
Line coordinates parameter or texture coordinate parameter.
12. devices according to claim 11, it is characterised in that described diagram parameter merges module,
Including:
The packed array memory element of parameter, for by the normal coordinate parameter of described first geometric model or stricture of vagina
Reason coordinate parameters be stored in parameter packed array in；
The packed array adding device of parameter, for will find described repetition geometry mould in described drawing area
The described normal coordinate parameter of type or described texture coordinate parameter make an addition to described parameter packed array in；
The packed array signal generating unit of parameter, is used for traveling through described drawing area, generates described parameter packed array.
