Detailed Description
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The method aims to solve the technical problems that the manufacturing cost of the hard surface model is increased and the processing efficiency of the hard surface model is influenced when the hard surface assets with lower importance degree are manufactured through the conventional process at present. The embodiment provides a method for processing a hard surface model, as shown in fig. 1, the method includes:
The hard surface asset may be a model of an item having a hard surface, such as a vehicle, weaponry, architectural structure, etc. in a game.
White mode (Mockup), also known as gray mode (Block out), is a rough model in which the basic geometry is roughly modified at the beginning of model creation to render the modeled object volumes, shapes, proportions, spatial relationships.
And 102, adjusting the modeling outline and the proportional relation of the white mould data of the hard surface asset to obtain middle and high mould data.
Different from the mode that middle mold data needs to be manufactured and then high mold data is manufactured through the middle mold data in the prior art, the method does not need to directly adjust the modeling profile and the proportional relation of the white mold data of the hard surface asset to obtain the middle and high mold data with the precision between the middle mold and the high mold, the middle and high mold is different from the high mold of the traditional process, the topological structure of the model can be not paid attention to a great extent, and the model can be manufactured and molded quickly.
The middle module (Mid Poly) is a middle module in the art asset model making process, has details required to be presented by design, can be converted into a High module (High Poly) by tessellation by adding a control line, and can also be used for adjusting a topological structure and reducing the number of surfaces into a Low module (Low Poly). The low modulus is a low precision (relative) 3D model for real-time rendering. The high-modulus is a high-resolution high-precision model with a large amount of details, and a manufacturer can realize various details in the design by manufacturing the high-modulus, but the high-precision model cannot be used for real-time rendering, and needs to bake the detail information to the texture through a baking process and apply the high-modulus to the low-modulus in the real-time rendering process.
The medium-high mode in the present embodiment is different from the medium-high mode in the conventional sense because all the details required to be expressed in structure and surface are already made, but is different from the high mode in the conventional sense because the surface subdivision is not required, so the number of peaks/facets is not high, and is called medium-high mode.
The manufacturing of the medium-high mold is very simple compared with the manufacturing of the high-high mold, and only the molding and the proportion need to be concerned, and the control line does not need to be added in a wire clamping mode and the like. For example, as shown in the medium-high mode example shown in fig. 2, it can be seen that the number of vertices and the number of faces are relatively very small, and the manufacturing difficulty is very low. In order to facilitate the fusion between different models, cutting openings, gaps, transition between different shapes and the like on the medium-high model do not need to be considered.
A chamfer Shader (BevelShader), or called Round Corner Shader (Round Corner Shader). The tool for performing the method of this embodiment requires the pre-implantation of an offline renderer with Round Corner/Bevelshader. And then, the edge of the hard surface model is automatically processed by using the characteristic of Round Corner/Bevelshader of the offline renderer, details and effects which can be achieved only by manufacturing a high-precision model under the traditional process are generated, and the method is applied to the real-time rendering workflow in a game through data baking.
For example, after the medium-high mode is manufactured, a material needs to be specified for the model, and then a BevelShader is applied, the parameter of the BevelShader determines the width of the finally generated chamfer, different edges of the model may exist, and different chamfer widths need to be used, in this case, different materials need to be specified for the surface where the edge is located, and a parameter which is expected to be used is set.
And step 104, baking and converting the middle and high modulus data after the chamfer coloring device is applied into a normal line mapping.
In this embodiment, in order to render in real time in the game, the effect after applying Bevelshader is also required to be converted into a Normal Map (Normal Map) by baking.
Baking (Baking) to Texture (Texture): in the process of producing a game art asset, the baking refers to a production technique of baking the detailed information of the high-precision model, for example, the information of the normal direction, the surface curvature, and the like, on the texture with reference to the normal direction of the vertex of the low-precision model and the UV texture map coordinate information. The low-precision model will use the results of the baking to present details close to the high-precision model when rendered in real-time. The various information textures generated by baking are also used to provide surface feature information to the algorithm during the process of programming the material.
In the embodiment, a high-precision model (namely a high model) for subdividing the surface is not required to be manufactured, the edge of the hard surface model is automatically processed by utilizing the characteristics of the chamfer shader, details and effects which can be achieved by manufacturing the high-precision model under the traditional process are generated, and the high-precision model is applied to a working process of real-time rendering in a game through data baking.
And 105, rendering according to the normal map and the low modulus data of the hard surface asset to obtain the image data of the hard surface asset.
Compare with the mode that the hard surface asset that is less to the important degree was whole according to current flow preparation at present, this embodiment because need not make the high accuracy model of subdivision surface, so can be to a certain extent in the manufacturing process disregard the wiring and the topological structure of model, and no longer restrict the preparation mode of model, and then saved great work load. The hard surface assets with low importance degree are processed by the technical scheme provided by the embodiment, the manufacturing complexity can be reduced on a large scale, the manufacturing period is shortened on the premise of maintaining the same quality, the manufacturing cost of the hard surface model can be saved, the processing efficiency is improved, and the technical capability requirements of hard surface asset makers can be reduced because high molds are manufactured in modes of polygonal modeling, surface subdivision and the like.
Further, as a refinement and an extension of the specific implementation of the above embodiment, in order to fully illustrate the implementation of the embodiment, another hard surface model processing method is provided, as shown in fig. 3, the method includes:
In the embodiment, because the high-precision model for subdividing the surface is not required to be manufactured, the wiring and the topological structure of the model can be ignored to a certain extent in the manufacturing process, the manufacturing mode of the model is not limited any more, and various processes such as polygonal modeling, curved surface modeling, Boolean modeling and the like can be used for generating the medium-high model for baking data.
For the embodiment, the low modulus data obtained by adjusting the white modulus data or the low modulus data of the hard surface asset and the like can be obtained by adjusting the medium modulus data and the high modulus data after the medium modulus data and the high modulus data are obtained, so as to meet different requirements.
The embodiment can be applied to Digital Content Creation (DCC) software implanted in an offline renderer of Round Corner/surface Shader, and can not be limited to software tools such as Blender/Modo/Houdini/Maya/3 dsmax. Therefore, the working mode is flexible and changeable, and the working process can be customized at will. If the user is not satisfied, because the mainstream DCC software supports Open Shading Language (OSL), the user can also choose to realize the DCC software by the OSL on the basis of theory.
Optionally, step 203 may specifically include: based on the specified material, the number of the light rays participating in calculation is set through sampling precision, and the edge width after chamfering is adjusted.
For example, the flow of applying Round Corner/measure Shader may differ for different DCC software/rendering environments. Taking the blend tool as an example, the Round Corner/level Shader is applied by adding level Node to normal input of the main BRDF in the material editor; taking the Maya tool of Arnold as an example, a Round Corner/surface shade is required to be set and applied in a Node Editor; for the 3dsmax tool, Round Corner/novel shade Shader is applied to match Arnold setting in the Slate tool; for Modo software tools, Round Corner/measure Shader is applied to the Surface Normalm panel setup of model attributes.
Whatever software tool environment is used above, the key parameters include: sampling precision (Sample) and chamfered/rounded edge width (Radius). Wherein, the sampling precision is used for setting the number of light rays participating in calculation, and the quality of the smooth/chamfer is determined; the chamfered/rounded edge width requires the user to adjust as desired during fabrication. After these settings, the effect of the medium-high mode with the Round Corner/level shade applied is shown in FIG. 4.
And step 204, baking the medium and high modulus data after the chamfer shader is applied to the normal mapping by utilizing a baking tool of the digital content creation software.
The texture baking process of different DCC software is different, for example, taking a Blender tool as an example, a high mode (highlift) is selected from the Blender tool as a middle-high mode after Round Corner/level shade is applied; and the Low modulus (Low Poly) is a model for real-time rendering in the game, and becomes the Low modulus in the game. The DCC self-baking function is utilized to bake the effect of the middle-high mode + Round Corner/Bevelshader to the normal mapping, and the normal mapping is applied to the Low mode in the Low Poly game during real-time rendering, so that the Low mode looks like the effect of a high-precision model.
And step 205, rendering by applying the normal map on the low-modulus data to obtain image data of the hard surface asset.
For example, as shown in FIG. 5, a normal map is generated for the low-mode and previous flow in the game for real-time rendering, from the high-mode baking; as shown in fig. 6, a rendering effect diagram (Unity3D) in the game engine is shown.
In order to further improve the rendering effect, optionally, step 205 may specifically include: baking to generate other supporting textures for describing model surface features by using low-modulus data and a normal line mapping of the hard surface asset; and rendering the low-modulus data by applying the normal mapping and the other supporting textures for describing the surface characteristics of the model to obtain the image data of the hard surface asset.
For example, other supporting textures describing surface features of the model may be generated simultaneously during the baking of the normal Map, such as a Cavity Map (Cavity Map), a Curvature Map (Curvature Map), a Thickness Map (Thickness Map), and so on. For example, the normal mapping obtained by low-mode and baking is imported into a substance pointer to create a new project, and then various auxiliary support textures are generated by baking. These textures provide the basic data for subsequent programmatic generation within surface texture production software (Substance Designer, Substance pointer, etc.). After texture drawing is completed in the Substance pointer, various textures (such as fixed color, normal mapping, roughness texture and the like in a PBR (basic character representation) metal degree flow) required by in-game rendering can be derived, and the textures are matched with low modulus used in the game to perform real-time rendering in the game.
In this embodiment, in order to automatically process the edge of the hard surface model by using the characteristics of Round Corner/BevelShader of the offline renderer, the edge is mainly judged during rendering, and additional normal vector information (with multiple implementation methods) is added to a vertex (where the vertex is located at a position that needs to be rounded) to simulate the effect of edge rounding. That is, the above-mentioned applying normal map and other supporting textures to the low-modulus data to render and obtain the image data of the hard surface asset may specifically include: the method is characterized in that an off-line renderer with a chamfer shader implanted in advance is utilized, and extra normal vector information is added to a vertex based on the chamfer width through edge judgment during rendering so as to simulate the effect of edge smooth chamfering.
The manufacturing process of the hard surface model is a high-precision model obtained by traditional polygon modeling and surface subdivision at present, namely after the manufacturing of the intermediate model is completed, the manufacturing of the high-precision model with a large amount of details is completed by adjusting model wiring, increasing control lines and subdividing the surface of the model. If necessary, the high die is also required to be led into digital engraving software for additional detail production, and after the detail production is completed, the high die of the software is subjected to surface reduction for texture data baking production.
Or industrial modeling software is used for model making, the model is converted into a polygon for topology conversion, and then the final high model is obtained. For models with large numbers of surfaces and cuts, the NURBS surface modeling technique using industrial modeling software (Fusion 360, Rhinoceros, etc.) has a great speed advantage. The model constructed based on the Nurbs mode can be effectively converted into the polygon model, but because the topological structure of the polygon model generated by normal conversion cannot meet the requirement of a surface subdivision algorithm to obtain a smooth and flat result, the topology of the conversion result is usually modified.
At present, each scheme in the prior art is generated by the problems to be solved and the application environment, the high-precision hard surface asset production in games is firstly generated in 3A works of science fiction subjects, large-screen high-definition pictures have certain requirements on details, but certain defects exist, and the process is more obvious when applied to mobile equipment with smaller screens. The prior art flow scheme can not cover the generation of various types of assets, the quantity of the hard surface assets related to the background is large, the importance degree is low, the prior art flow is too complex in process, for example, a large number of props in a scene are produced, and if the hard surface assets are all produced according to the prior art flow, the workload and the cost are easily out of control. The manufacturing process of the existing scheme is destructive and irreversible, and partial or even whole model adjustment is inevitably caused for the change of the setting (the configuration of the model is usually obtained by using basic body Boolean, generally, in the manufacturing process, in order to enable model wiring to meet the operation of subdividing the surface, the result of Boolean operation needs to be collapsed, then the wiring of the model needs to be edited, if partial design or the proportional relation is modified, the above process needs to be repeated, and the operation of Boolean- > collapse- > wiring editing needs to be carried out again). And it is difficult to quantify some details of the manufacturing process, such as the chamfer width of the model edge and the width of the highlight generated by the chamfer, and it is likely that after the manufacturing is completed, different model assets are found to present different chamfer widths and highlight widths in the picture, which directly affects the uniformity of the picture and the volume of the model itself.
Besides key props (weapons and the like), a large number of hard-surface assets are low in importance in the art assets of games, but the requirements of the current manufacturing process flow on art manufacturers are high, the polygon modeling and surface subdivision mode requires the manufacturers to have good understanding on the wiring topology of the model, and satisfactory results can be obtained efficiently by combining a large number of auxiliary tools with certain processing experience. The industrial auxiliary curved surface modeling mode needs to additionally learn the working mode of the curved surface modeling and master related software, a certain threshold exists in the cross-field cooperation, and the mass production of personnel with flow splitting and matching capability is difficult to realize.
In order to solve the above problems, with the method of this embodiment, because there is no need to make a high-precision model (i.e. a high-modulus) for subdividing a surface, the layout and topology of the model can be ignored to some extent during the making process, and the making mode of the model is not limited any more, thereby saving a large amount of work. The manufacturing complexity can be reduced on a large scale, the manufacturing period is shortened on the premise of maintaining the same quality, and the cost is reduced; reducing the technical capability requirements of hard surface asset makers; all the manufacturing links are decoupled, and independent workflows can be designed in each link, so that the industrial and automatic production is facilitated. And a non-destructive modeling workflow is provided to a certain extent, so that modification cost brought by design change is facilitated. If the new flow is used, the Boolean result can be directly used without surface subdivision, the Boolean operation state is reserved, and the model of the elements participating in the Boolean operation in real time can be adjusted at any time to obtain the final result.
