Specifically, step 603 includes: according to the corresponding attribute value of the drafting control, weight coefficient and the grid
Product of the vertex at a distance from the central point for drawing control determines the attribute of the grid vertex within the scope of the drafting control
Value.
By this step, the central point that distance draws control is closer, and the attribute value of grid vertex is smaller.
By taking color attribute as an example, it can be set that attribute value is smaller, and color is deeper；Attribute value is bigger, and color is more shallow.In this way,
Grid vertex is closer with a distance from the central point for drawing control, and color is deeper；Distance is remoter, and color is more shallow.
Certainly, the attribute value for drawing the grid vertex within the scope of control can also be arranged by other means, such as right
The attribute value for drawing the grid vertex within the scope of control does not distinguish, and is uniformly set as an attribute value.
604, according to the attribute value of grid vertex, the attribute value of the grid is determined.
By taking triangular mesh as an example, the attribute value needs of the grid are determined according to the attribute value on three vertex.
It is moved at the next position drawing control, re-execute the steps 601~604, realized within the scope of drafting control
Model attributes value setting.In this way, user, which only needs first to define, draws the corresponding attribute value of control, mouse control is then operated
System draws control actions, it can neatly carries out setting for model attributes value by any position drawn in control Selection Model
It sets, to operate freedom degree height, is conducive to quickly handle.
Wherein, attribute value can be a variety of, such as attribute value may include: color value, it is weight value, bone weighted value, hard

Weight degree；
By taking bone weighted value as an example, in 3D animation system, the bone weight for drawing control setting animation can be used, such as
The amplitude weight that grid vertex deviates in movement.
Furthermore it is also possible to by the drafting of the color value to grid vertex so that attribute value can by color value come into
Row identification.By taking a person model as an example, silk is indicated with blue, and color is more blue, indicates that silk is more soft；Gold is indicated with red
Belong to the armor, color is redder, indicates that the armor is harder.
It is then possible to indicate these speciality with color value on grid vertex by drawing control, but actually use
When, the meaning that these color values just have other special, this is meant that can be by using the user for drawing control to make by oneself
Justice.Such as: the hardness range that can define the armor is red=0 between 0~100, indicates that armor hardness is 0, red=255, table
Show that armor hardness is 100.
The method of model setting provided by the present application will by determining direction ray according to selected point and virtual camera
