The present invention relates to a method and an apparatus for implementing an effect in a game engine. More specifically, when a technique for implementing an effect is set in a visual, the technique calls a render context of the visual in a technique and requests a render context to be registered in a phase. The present invention relates to a method and an apparatus for implementing an effect by registering a render context modified in a phase in a view.

In general, three-dimensional applications with the development of graphics hardware support an increasingly diversified special effects, and requires a lot of attribute data to implement the effects.

Modern graphical application programming interfaces (APIs) provide a format for attribute data, called the FX format.

However, since the conventional FX format is simply a structure having only data, there is a problem in that the process and the target of rendering other than the data cannot be changed.

Therefore, in order to implement various effects in order to use the conventional FX format in the game engine, it requires a long time because a lot of attribute data for each effect is required.

The present invention has been made to improve the prior art as described above, it is an object of the present invention to provide a method and apparatus for quickly implementing the effect as independently as possible in the game engine.

An object of the present invention is to provide a method and an apparatus for implementing an effect using an FX format that can freely change the process and object of rendering in addition to attribute data in a game engine.

Another object of the present invention is to provide a method and apparatus for implementing an effect that supports a flexible structure in which a rendering pipeline can be changed into a script and an FX format in a game engine.

In order to achieve the above object and solve the problems of the prior art, the present invention comprises the steps of owning a render context (Visual) in the visual (Visual), requesting the registration of the render context in the view (Visual), If a technique for implementing a predetermined effect is set in the visual, delegating a registration of a render context to the technique in the visual; loading the render context information owned by the visual in the technique; Requesting a registration of a render context at the phase, modifying the render context based on the transformation data set according to the effect at the phase, and registering the modified render context with the view at the phase. It provides a method for implementing an effect, characterized in that.

An apparatus for implementing an effect in a game engine according to an aspect of the present invention includes a view requesting registration of rendercontext information, a request for registration of render context information from the view, and a predetermined effect implementation. A visual for delegating the registration of the render context information, a technique for delegating registration of the render context information from the visual and retrieving render context information possessed by the visual, and the render context information from the technique And a phase for requesting the registration of the information, modifying the render context information, and registering the modified render context information in the view.

The FX format according to the present invention involves three objects, such as effects, techniques, and phases, and can change the level of the rendering pipeline such as the rendering process, the target, the number of times, and the like in addition to the attribute data. An effect object according to the present invention is a unit of abstract effects, a technique object is a unit of concrete implementation, and a phase object is a detailed unit of a picture.

Hereinafter, a method and an apparatus for implementing an effect in a game engine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a render context class diagram in a game engine according to the present invention.

Referring to FIG. 1, the base render context 100 includes a rendering state, a material, a rendering command, a transform, and the like, and exposes information of a rendering. The rendering state includes various values corresponding to a state for rendering such as transparent, opaque, increasingly transparent in opacity, increasingly transparent in opacity, and the like. The material includes brightness, texture images, and the like, and the transform contains perspective information such as drawing from far to near. Accordingly, the basic render context 100 refers to information related to rendering of a visual that is an object of image implementation, and may be involved in rendering of the visual to realize indirect rendering of the visual. The basic render context 100 includes information on how to visualize the visual when visualizing the image in the game (image realization). For example, the rendering level information, the rendering texture information, By including rendering brightness level information, rendering perspective information, and the like, it is possible to participate in the rendering process of the visual. The default render context 100 may be generated in advance by, for example, a visual creator associated with the visual 120, and the game engine of the present invention uses the first render context generated by the visual author to visually generate the visual 120 ) Can also be processed for rendering.

The render context 105 is a materialized render context and includes type information T_Type. That is, the render context 105 includes one or more of rendering level information, rendering texture information, rendering brightness information, and rendering perspective information for the visual 120 (visual object). Visual 120 maintains render context 105 to render a given object.

The view 110 requests the visual context 120 to register the render context and sorts the render context to be registered. That is, the view 110 receives a rendering command for an object from a game application and requests the visual 120 for a render context corresponding to an attribute of the object to perform rendering of the object. The object is an object represented in the view 110, and includes an object to be represented, for example, an apple, a tree, a person, the sun, a background, a shadow, and a desk. In addition, the object has attributes such as texture information, brightness level information, perspective information, and type of the object, and the view 110 confirms the attributes of the object. For example, the view 110 requests the visual 120 to register the render context, meaning "what kind of render content is required to render an object of a certain attribute?". The game application determines the sorting order according to the execution of the render context according to the pre-generated rendering order, and thus the render context is sorted.

Visual (120) owns the render context and registers the render context owned by the view (110). Visual 120 may own one or more render contexts. That is, the visual 120 checks the render context owned by the visual 120 and provides the render context to the view 110 in response to a request for registering the render context received from the view 110.

2 is a diagram illustrating a process of collecting a general render context in a game engine according to the present invention.

1 and 2, in step 210, the view 110 requests registration of a render context for all registered visuals 120. That is, in step 210, the view 110 receives a rendering command for an object from a game application, and requests the visual 120 to register a render context corresponding to an attribute of the object in order to perform rendering of the object. do.

In operation 220, the visual 120 registers a render context owned by the view 110 to the view 110. That is, in operation 220, the visual 120 checks the render context and provides the render context to the view 110 in response to a request for registration of the render context received from the view 110.

3 is a diagram illustrating a procedure of performing rendering in a view of a game engine according to the present invention. When a rendering command is given to each view in the game engine, the following processing is performed.

1 to 3, in step 310, the view 110 collects a render context from the game engine according to a rendering command. The view 110 collects the render context according to the registration procedure of the render context as shown in FIG. 2.

In step 320, view 110 performs a sorting on the collected render context.

In step 330 the view 110 calls the render commands of the render context in the sorted order.

In step 340, view 110 performs rendering in accordance with the called rendering command.

4 is a diagram illustrating a structure of an effect implementing apparatus in a game engine according to an exemplary embodiment of the present invention, wherein the effect implementing apparatus 400 includes a view 410, a visual 420, a technique 430, and a phase. 440.

Referring to FIG. 4, the view 410 requests a registration of a rendercontext from the visual 420. The renderkentext is owned by the visual 420 and is an information structure including a rendering state, a material, a rendering command, or a transform for rendering. The view 410 performs the sorting by collecting the render context according to the command of the game engine, and performs rendering by calling the render commands of the render context in the sorted order.

The visual 420 is requested to register the render context from the view 410, and when a technique for implementing a predetermined effect is set, the visual 420 delegates the registration of the render context to the technique 430.

The technique 430 delegates registration of the render context from the visual 420 and calls the render context owned by the visual 420. Technique 430 also duplicates the render context owned by visual 420 and requests phase 440 to register the cloned render context.

Phase 440 receives a request for registration of the render context from technique 430, modifies the render context, and registers the modified render context in view 410. That is, the phase 440 assigns a phase attribute according to the modified data to the duplicated render context and then registers the modified render context in the view 410.

5 is a diagram illustrating an effect related class diagram in the game engine according to the present invention.

Referring to FIG. 5, the GoEffect 510 includes abstract and comprehensive implementation condition information, the GoTechnique 520 includes specific implementation condition information, and the GoPhase 530 technique. Contains detailed implementation condition information constituting. The high technique 520 holds processing capability information, that is, specific implementation assistance information, that is, information about a rendering context of the render context according to hardware performance of the production tool module. The high phase 530 includes rendering texture information, rendering brightness level information, rendering perspective information, and the like as implementation condition information according to the render context registration request, and determines an effect level for the render context. In addition, the high phase 530 holds information on the detailed rendering process of the visual as implementation condition information, and visuals implemented as an image using a render context converted according to the implementation condition information are used to generate characteristic game effects in the game. Make it work.

The FX format to which the present invention is applied involves three objects, effects, techniques, and phases, and not only plays a passive role of providing data, but also changes the level of the rendering pipeline such as the rendering process, the target, and the number of times. Can give In addition, the present invention can be supported by a script so that the effect production can proceed as quickly and independently as possible. In order to implement this, the present invention converts the rendering engine of the game engine into a flexible structure that can change the script and FX formats, and performs a preprocessing operation of embedding the script language. The preprocessing task is to select an object to which the corresponding technique is to be attached, and the postprocessing task is to serve as a bridge in the restoration or continuous effect.

6 is a flowchart illustrating a method of implementing an effect in a game engine according to an embodiment of the present invention.

Referring to FIG. 6, in operation 610, the view requests a visual of registration of a rendercontext. The render context is owned by the visual and is an information structure containing a rendering state, a material, a rendering command, or a transform for rendering. That is, in step 610, the view receives a rendering command for an object from a game application, and requests the visual to register a render context corresponding to an attribute of the object in order to perform rendering of the object. The object is an object represented in the view, and includes, for example, an expression object such as an apple, a tree, a person, a sun, a background, a shadow, a desk, and the like. In addition, the object has attributes such as texture information, brightness level information, perspective information, type of object, and the like, and the view identifies the attribute of the object. For example, the view requests registration of the render context to the visual, meaning "what kind of render content is required to render an object of an attribute?" The game application determines the sorting order according to the execution of the render context according to the pre-generated rendering order, and thus the render context is sorted.

In step 620, the visual delegates registration of the render context to the technique when a technique for implementing a predetermined effect is set. The effect is a unit of abstract effect, the technique is a concrete implementation unit, and the phase is a detailed unit of a picture. That is, in step 620, if the technique is set to implement the effect desired by the user in the render context, the technique registers the render context so that the render context to which the effect is applied is registered in the view. To delegate.

In step 630, the technique loads a render context owned by the visual, and requests phase registration of the render context. The technique is set in the visual or deleted from the visual depending on whether the effect of the render context is implemented. That is, the technique is set in the visual when the effect is to be implemented in the render context, and the set technique is deleted from the visual when the effect is not implemented in the render context. Therefore, when the effect is to be implemented in a render context owned by the visual, a technique corresponding to the effect is set, and when the effect is not implemented, the corresponding technique is deleted.

The technique is set in the visual or deleted from the visual depending on whether the render context implements an effect.

Step 630 includes duplicating a render context owned by the visual in the technique and requesting the phase to register the duplicated render context.

In step 640, the phase transforms the render context according to the transformation data set in the phase, and registers the modified render context in the view.

In step 640, the phase transforms the render context based on the transformation data set according to the effect, and registers the modified render context in the view. That is, in step 640, the phase modifies the render context by applying a given phase attribute to the duplicated render context based on the transform data set according to the effect, and replaces the transformed render context with the visual. Register with the view. As such, the phase may apply a predetermined modification to the render context to implement the effect, and register the modified render context in the view on behalf of the visual.

As such, the technique and phase take a render context owned by a general visual, make various modifications, and register the modified render context with the view requesting the visual instead of simply registering the visual and other special effects. Can provide. The technique can be freely attached or deleted at all times at any time, thereby supporting pluggable special effects.

The view performs sorting by collecting the registered render context according to the command of the game engine, and performs rendering by calling the rendering commands of the render context in the sorted order.
