Abstract

The invention relates to the field of computer graphics, in particular to skin construction technology aiming at low polygons. Aiming at the character that graphic designers need to carry out 100 percent control to vertex effect in the low polygons, the invention provides the quick skin construction technology. According to the quick skin construction technology, development time of the graphic designers is greatly shortened. Compared with high polygon models, the edges of the low polygons are smoother, a plurality of bones are needed to influence a vertex, then a plurality of indicators pointing at bones influencing the vertex need to be stored for each vertex, and therefore an inverse transformation vertex can not be stored in advance.

Description

A kind of dermal composition technology of Simple fast

Technical field

The present invention relates to the computer graphics field, more particularly, is a kind of dermal composition technology.

Background technology

Along with the development of online game, promote rendering efficiency and become more and more important.Because the player is more and more higher to the requirement of the view effect of game, so, for some model and scenes that does not need large accuracy of measurement, will be optimized.

Promoting more direct way of frame per second is to subtract face.Because a lot of models do not belong to player's focus, just can adopt the minimizing number of vertex to improve frame number.

Summary of the invention

Problem in view of prior art exists the present invention is directed to lower polygon, and in low polygon, the art designing need to carry out 100% characteristic of controlling to the summit effect, has proposed a kind of fast dermal composition technology, has greatly reduced art designing's development time.

To achieve these goals, the technical scheme that this law adopts is a kind of dermal composition technology of Simple fast, and concrete steps are as follows:

1) creates low polygonal model;

2) model is dwindled according to minimum ratio, and continue the skin stripping and slicing that these are little to less part, they are used as bone;

3) when all bones create complete after, just be presented a name that an additional numerical values arranged the same as skin, he will be used as bone by procedure identification;

4) get the solid of bone and with the source, summit in a large tabulation, every record in this tabulation all comprises the bone information that vertex position and this summit belong to;

5) for each summit on the skin, we seek the summit the most close with him in the bone tabulation, and the inverse matrix conversion is carried out by its most close summit in the skin summit, and this just transforms to the skin summit in the local coordinate system of bone;

6) index and pointer that points to the bone that affects it of original vertices tabulation also stored in the source, summit of conversion in the temporary table of an accumulation, and what affect its bone has a counter to record the summit number of his conversion.

Method of the present invention is quick and simple, and is particularly useful for low polygon.For high polygon model, its edge is more level and smooth, just needs several bones affect a summit, need to store the pointer that a plurality of sensings affect its bone for each summit so for a long time, and this means can not pre-stored inverse transformation summit.

Embodiment

A kind of dermal composition technology of Simple fast, concrete steps are as follows:

1) creates low polygonal model;

2) model is dwindled according to minimum ratio, and continue the skin stripping and slicing that these are little to less part, they are used as bone;

3) when all bones create complete after, just be presented a name that an additional numerical values arranged the same as skin, he will be used as bone by procedure identification;

4) get the solid of bone and with the source, summit in a large tabulation, every record in this tabulation all comprises the bone information that vertex position and this summit belong to;

5) for each summit on the skin, we seek the summit the most close with him in the bone tabulation, and the inverse matrix conversion is carried out by its most close summit in the skin summit, and this just transforms to the skin summit in the local coordinate system of bone;

6) index and pointer that points to the bone that affects it of original vertices tabulation also stored in the source, summit of conversion in the temporary table of an accumulation, and what affect its bone has a counter to record the summit number of his conversion.
