In the embodiments of the application, the front direction of the game role is taken as the front, and the back direction is taken as the back; the hair of the game role is inner near the scalp and outer far from the scalp.
First, a method for rendering hair of a game character according to an embodiment of the present invention will be described.
Fig. 1 is a flowchart of a method for rendering hair of a game character according to an embodiment of the present disclosure. As shown in fig. 1, the method comprises the following steps S11-S14.
S11, obtaining hair pieces obtained by splitting a hair model and a hair group consisting of the hair pieces;
step S12, for each hair group, determining a first rendering sequence of each hair piece according to a first distance between each hair piece in the hair group and the center point of the hair group and a sequence of the first distances from near to far;
step S13, for each hair group, determining a second rendering sequence of each hair group from back to front by taking the front of the game role as a reference;
and S14, rendering the hair model according to the first rendering sequence and the second rendering sequence to obtain the rendered hair model.
The respective steps in the above-described embodiment method are explained in detail below.
(1) With respect to step S11
Because the number of hairs is large, the types and styles of the hairs are various, the colors are different, and complicated hair rendering may occupy a large amount of rendering resources, the hair model of the game role is generally manufactured based on a patch, that is, the whole hair model is composed of a plurality of hair patches (hereinafter referred to as "hair patches"). And 3dsMax, MAYA and other software are used for placing the hair pieces according to the hair growth rule, carrying out UVW expansion on the hair pieces, and placing the hair paste picture on the corresponding UV position, thereby simulating the real hair effect.
As shown in FIG. 6, the hair of the game character is composed of a plurality of hair pieces, and each hair piece 61 can be edited and adjusted independently.
For a patch-based hair model, the hair model may be split using a splitting (DETACH) element, for example, using a command poly op.
In this step, a hair group consisting of the hair pieces is also obtained, that is, the hair pieces obtained after the hair model is split are grouped. Obtaining a set of hair comprised of said pieces of hair comprises: and grouping the hair pieces according to the hair piece types corresponding to the hair pieces to obtain the hair group.
The hair piece type can be determined in various ways, for example, the hair piece type can be determined by the position relation of the hair piece and the head, or the hair piece type can be determined based on the hair style of the game character.
(2) With respect to step S12
For each hair group, the location of its center point is determined. The central point of the hair set may be the central point of the hair set in the world coordinate system, or the central point of the hair set in the camera coordinate system, or the like. The whole hair model and the central point are positioned in the same coordinate system, so that the distance between the hair piece and the central point can be accurately calculated in the following process.
The position of the center point of the hair group can be calculated based on the position of the center point of each hair piece in the hair group, and can also be specified according to the position of the hair group. For example, if the hair group is a hair portion wrapped around the scalp, the center point of the hair group may be set as the center of the game character's head; if the hair group is a chignon part located on the top, on the side of the head or behind the brain, the center point of the hair group can be set as the center position of the chignon; if the hair group is a horse tail, the center point of the hair group is positioned in front of the middle part of the horse tail.
For each hair piece in the group, its distance from the center point of the group is calculated, close, i.e. the first rendering inside the group, and far, i.e. the last rendering outside the group.
(3) With respect to step S13
Since each hair group is also in front-back order visually, the rendering order of each hair group needs to be determined before rendering. And rendering from back to front according to the front-back sequence viewed from the front of the game character, namely the hair group which is actually in front is also in front visually, so that the combined hair model visually conforms to the natural law.
(4) With respect to step S14
After the rendering order of the hair pieces and the rendering order of the hair groups are obtained, the hair pieces and the hair groups can be rendered in sequence.
This application embodiment, after the hair model split is the hair piece automatically, divide into groups according to the order of from inside to outside and render, the hair group after will rendering combines according to the order of seeing from the game role openly from the back to the front, like this, the hair that lies in the hair inboard or rear side is rendered earlier from the vision, and is rendered after the hair that lies in the hair outside or front side, when guaranteeing that the hair renders lifelike lively the effect, realize that the hair model is rendered according to accurate order automatically, avoid manual sequencing to waste time and energy, the treatment effeciency and the degree of accuracy of game role hair are improved.
In alternative embodiments, grouping the hair pieces based on their types may be in any of the following ways.
In a first mode
And grouping the hair pieces according to the hair piece types corresponding to the hair pieces to obtain the hair group, wherein the steps A1-A3 are included.
A1, acquiring the position relation between each hairpin and the head of the game character, wherein the position relation at least comprises the distance between each hairpin and the head of the game character;
step A2, classifying the hair pieces according to the position relation to obtain the hair piece types;
and A3, grouping the hair pieces according to the hair piece types to obtain the hair group.
In this aspect, a plurality of distance threshold ranges may be set, and the hair pieces located within a certain threshold range from the head of the game character may be classified into the same type and the same group. Therefore, the obtained multiple hair groups are divided according to the distance between the multiple hair groups and the head of the game role, each hair group is rendered from inside to outside according to the distance between the hair piece and the central point, the hairs with different distances from the head of the game role are rendered according to the correct sequence, the rendered hair groups are combined from back to front, and each hair group is also combined from far to near from the scalp actually, so that the rendered hair visual effect is more consistent with the natural law, and the whole hair rendering effect is more vivid.
Mode two
Grouping the hair pieces according to the hair piece types corresponding to the hair pieces to obtain the hair group, wherein the hair group comprises:
step B1, acquiring the hairstyle type of the game role;
b2, determining the hair style corresponding to each hair piece according to the hair style type;
and step B3, grouping the hair pieces according to the hair piece types to obtain the hair group.
Optionally, when the hair style is horse tail, the hair piece types include: scalp hair and horsetail hair; the step B3 includes: and according to the hair piece types, dividing the hair pieces into groups to obtain a scalp hair group and a horse tail hair group. If the hairstyle is horsetail, the hair wrapped on the scalp can be divided into one group, and the horsetail part can be divided into another group.
Optionally, when the hair style type is a bun, the hair style type includes: scalp hair and bun hair; the step B3 includes: and according to the hair piece types, dividing the hair pieces into groups to obtain a scalp hair group and a chignon hair group. If the hair style is a hair bun, the hair wrapped around the scalp can be divided into one group, and the hair bun parts can be divided into another group.
In this manner, if the hairstyle is short, all of the pieces of hair can be grouped together; if the hairstyle is a shawl hair, the hair wrapped around the scalp can be divided into one group, and the hair on the shawl part can be divided into one group. There are various types of hair styles, which are not described in detail herein.
As shown in FIG. 7, the hairs of the game character are divided into two groups, a scalp hair group 71 is a part close to the scalp, and a long hair group 72 is a shawl hair part far from the scalp, as shown in FIG. 8.
As shown in fig. 9 and 10, the game characters are divided into two groups, a scalp hair group 81 at a portion close to the scalp, and a horse tail hair group 82 at a portion far from the scalp.
Therefore, the hair pieces are grouped through the hairstyle, the hair can be divided into relatively independent parts, each group of hair is rendered according to the sequence from inside to outside, the visual effect rendered by each part of the hair is in accordance with the natural law, and then all groups of hair are combined according to the sequence from back to front, so that the rendering effect of the whole hair is more vivid.
The hair pieces are grouped, and the two modes can be combined, namely the grouping of the hair pieces is determined by combining the positions of the hair pieces and the types of the hairstyles, so that for complex hairstyles, the hair pieces can be grouped, sequenced and rendered more accurately and effectively, and the visual effect of the finally combined hairstyle is more vivid.
In an alternative embodiment, fig. 2 is a flowchart of a method for rendering hair of a game character according to another embodiment of the present application. As shown in fig. 2, in the step S12, the process of determining the hair piece rendering process in each group specifically includes:
step S21, acquiring a first distance between each hair piece in the hair group and the center point of the hair group;
s22, sequencing the hairpieces according to the sequence of the first distance from near to far to obtain a first sequencing result; or, adding a first identifier for each hair piece according to the first distance, wherein the first identifier is used for embodying the sequence of the first distance from near to far;
and S23, determining the first rendering sequence according to the first sequencing result or the first identifier.
Optionally, in step S21, the distance between the hair piece and the center point of the hair set may be calculated as a distance between the center point of the hair piece and the center point of the hair set, or an average distance between each point on the hair piece and the center point, or a shortest distance or a longest distance between the hair piece and the center point is selected as a distance between the hair piece and the center point of the hair set, or a distance between the plane where the hair piece is located and the center point of the hair set is calculated, or a distance between the tangent line of the hair piece and the center point of the hair set is calculated, and so on. The designer can select any mode to calculate the distance between the hair piece and the center point of the hair group according to needs, and the specific calculation method is not described herein again.
Optionally, in step S22, for each hair group, a rendering order of each hair piece may be determined according to a distance between the hair piece and a center point of the hair group, in order to implement sequential rendering of the hair pieces, each hair piece may be directly and automatically sorted according to the distance, and sequentially rendered according to the order, or an identifier for identifying the rendering order may be added to each hair piece, and sequentially rendered according to the identifier during rendering. For example, a hair set contains 5 hair pieces: hair piece A, hair piece B, hair piece C, hair piece D and hair piece E. The distance between each hair piece and the center point of the hair group is respectively as follows:
hair piece A,6.89cm;
hair piece B,6.77cm;
hair piece C,5.98cm;
hair piece D,8.16cm;
hair piece E,7.32cm.
According to the distance from each hair piece to the center point of the hair group, the hair pieces can be sorted as follows: hair piece C-hair piece B-hair piece A-hair piece E-hair piece D, and rendering is carried out according to the sequence. Alternatively, the identification may be added to the hair piece according to the distance, such as, hair piece a: s3, hair piece B: s2, hair piece C: s1, hair piece D: s5, hair piece E: and s4. And during subsequent rendering, rendering is carried out according to the sequence of the identifiers s1-s 5.
In the embodiment, the sequencing of the hair pieces in the hair group is automatically completed by a tool, the manual sequencing of designers is not needed, the processing efficiency and the accuracy of the hair of the game role are improved, and the hair pieces are sequentially rendered from inside to outside, so that the visual effect of the rendered hair group is vivid and lively.
In an alternative embodiment, fig. 3 is a flowchart of a method for rendering hair of a game character according to another embodiment of the present application. As shown in fig. 3, in step S13, the process of determining the hair group rendering order specifically includes:
step S31, acquiring a second distance between the center point of the hair group and the camera when the front of the game role faces the camera;
s32, sorting the hair groups according to the sequence of the second distance from far to near to obtain a second sorting result; or adding a second identifier to each hair group according to the second distance, wherein the second identifiers are used for embodying the sequence of the second distance from far to near;
and step S33, determining the second rendering sequence according to a second sequencing result or the second identifier.
Optionally, in step 31, the distance between the hair group and the camera may be calculated by calculating the distance between the center point of the hair group and the camera, or the average distance between each point of the hair group and the camera, or selecting the shortest distance or the longest distance between the hair group and the camera, and so on. The designer can select any mode to calculate the distance between the hair group and the camera according to needs, and the specific calculation method is not described herein.
Optionally, in step S32, the merging order of the hair groups may be determined according to the distances between the hair groups and the camera, and in order to implement sequential merging of the hair groups, the hair groups may be directly and automatically sorted according to the distances, and sequentially merged according to the order, or an identifier for identifying the merging order may be added to each hair group, and sequentially merged according to the identifier.
For example, a hair model contains 3 hair groups: hair group G1, hair group G2, hair group G3. The distance between each hair group and the camera is respectively as follows:
hair group G1, 17.14;
hair group G2, 16.57;
hair group G3, 17.36.
The distance between each hair group and the camera may be sorted by: hair group G3-hair group G1-hair group G2, combined in this order. Alternatively, the patches may be marked by distance from far to near, e.g., hair group G1: n2, hair group G2: n3, hair group G3: n1. And merging according to the sequence of the identifiers n1-n 3.
In the embodiment, the sequential combination of the hair groups can be automatically completed by a tool without manual sequencing and combination of designers, so that the processing efficiency and accuracy of the hair of the game role are improved, and the hair groups are combined according to the sequence from far to near from the camera, so that the whole hair after final combination visually conforms to the natural law, and the effect is vivid.
In alternative embodiments of the present application, the step S14 may render the hair in two ways.
In a first mode
Rendering the hair pieces according to the first rendering sequence to obtain a rendered hair group; and rendering the rendered hair group according to the second rendering sequence to obtain the rendered hair model.
Namely, the hair pieces in each hair group are rendered in sequence at the same time, and the rendered hair groups are rendered in sequence.
For example, hair group G1, includes hair pieces A1-E1, and hair group G2 includes hair pieces A2-E2. Firstly, rendering the hair pieces A1-E1 in sequence to obtain a rendered hair group G1', and rendering the hair pieces A2-E2 in sequence to obtain a rendered hair group G2'. And then combining the hair groups G1 'and G2' according to the sequence to obtain the rendered hair model.
Mode two
And rendering the hair pieces in the hair group according to the first rendering sequence in sequence to obtain a rendered hair model.
For example, hair group G1, includes hair pieces A1-E1, and hair group G2 includes hair pieces A2-E2.
The rendering sequence of the hair groups is G2-G1, therefore, the hair pieces A2-E2 are rendered in sequence to obtain the rendered hair group G2', then the hair pieces A1-E1 are rendered in sequence to obtain the rendered hair group G1', and then the rendered hair model can be directly obtained.
In an alternative embodiment, after the hair pieces and the hair groups are sorted, a hair model in which the hair pieces and the hair groups are sorted can be generated instead of rendering the hair. The method further comprises the following steps: combining the hair pieces according to a first rendering sequence to obtain a target hair group; and combining the target hair according to the second rendering sequence to obtain the target hair model. In this embodiment, the target hair model includes target hair groups and a merging order of the target hair groups, and each target hair group includes a hair piece and a rendering order of the hair pieces. And during rendering, the finally output target hair model can sequentially render the hair pieces in each target hair group according to the combination sequence of the target hair groups, and finally obtain the rendered target hair model. The target hair model can be output and applied to different game roles so as to realize the makeup/decoration change of the game roles.
