The present invention relates to a three-dimensional graphics real-time screen output method based on the virtual reality, more specifically, the shape of the architectural design designed by the user and the change in the interior selected according to the real-time on the screen based on the virtual reality Virtual reality that enables you to check and instantaneously reflect various needs of customers by outputting and storing expressions by CAD engine on the screen in real time as 3D virtual reality, and to estimate the necessary data in real time The present invention relates to a 3D graphics real-time screen output method.

3D Graphics Drawing Program is a 3D graphics processing program that handles 3D shapes in computer graphics. Unlike a paint program that creates shapes from a set of pixels, it is possible to create circles, rectangles, The figure processing program which handles a line etc. as an object is called. For example, a user can manipulate an element such as a circle or rectangle, a line or a block of text as an independent object and simply select and move the object. Computer-aided design (CAD) is also a family of drawing programs. The representative software is MacDrawPro ™.

Conventional architectural design programs complete all 3D objects on the design screen, and then use a separate rendering engine to perform only a display function. The rendering engine considers the shape of an object in consideration of external information such as its shape, position, and light source, and uses computer graphics to express realistic images, that is, the final step when creating a computer graphics (CG) image in 2D or 3D. It is said to produce. In 2D computer graphics, rendering refers to a process of generating a processed image as a final step of an image processing process for a moving image and a still image.

Therefore, it is difficult for a user to change a desired interior object frequently while checking a screen displayed in three dimensions. It is difficult, and there is a problem that it is difficult to check in real time the change in the interior changes. In addition, the conventional architectural design program has a problem that it is difficult to simulate while freely moving in the completed three-dimensional model because the change of viewpoint is not free.

The technical problem to be achieved by the present invention is to check the screen displayed in three dimensions and to change the desired interior object from time to time and to change the changed interior in real time and the expression by the CAD engine in real time as a three-dimensional virtual reality It provides 3D graphics real-time display method based on virtual reality that reflects various needs of customers instantaneously by outputting and storing on the screen and necessary data can be quoted in real time.

Another object of the present invention is to provide a recording medium in which a program for performing the method is stored.

Referring to FIG. 1, in the 3D graphics real-time screen output method based on virtual reality according to an embodiment of the present invention, first, a wall drawing step is performed (step 10). The user completes a wall object by specifying only the start and end points of the wall on the screen. The finished wall has a start point, an end point, four corner points, a width, and a height.

FIG. 2 shows step 10 of FIG. 1 in more detail. Referring to FIG. 2, first, a user clicks a mouse at an arbitrary point on the screen to determine a starting point 302 as shown in FIG. 3A (step 102), the starting point information is determined. Next, the endpoint information is determined by dragging the mouse until the user reaches the desired wall length (step 104) and then clicking the mouse again to determine the endpoint 304 (step 106) when the desired wall length is reached. do. Next, a wall object in the form of a 3D object having six vertices is generated using the start point information, the end point information, the thickness information, and the height information (step 108).

Here, the 3D object is configured based on a triangle called a polygon, and a vertex means a vertex value of the polygon. These vertices are connected to create an object, which contains important basic information about the object. It has image information such as position value, color information, fog value, texture coordinates, and reflection value. The input vertex information is composed of wire frame by connecting and combining each vertex through the T & L engine. The outer surface of the three-dimensional modeled object is composed of a set of triangular nets, and the information of the triangle consists of three vertices of a triangle and a facet normal forming a triangle. Vertices refer to the corners where the triangle data that make up each 3D object meet. The game engine passes the objects on the screen to the graphics processor, which actually sends the vertex data for these objects. Each vertex contains a lot of information. First of all, vertices have three-dimensional coordinates x, y, z and w (weighted) information. It also contains color information, in some cases diffused or reflected color information. This color data is typically encoded in 'RGBA' format (R: red, G: Green, B: Blue, A: Alpha). Vertices are also accompanied by their normal information, which is a vector representing the orthogonal direction of the plane containing this vertex in a vector amount. It also contains texture coordinates (s, t, r, q) that indicate the location of the texture applied to the texture and vertices. In addition, when more than one texture is applied to a vertex, it contains texture coordinates corresponding to the number of textures applied to the vertex. In addition to fog information, the size of the point is accompanied. Also visible to the eye, the smallest unit that makes up a 3D scene, vertices, stores a lot of data needed to describe the scene.

Next, drawing another wall object 312 in addition to the wall object 310 created in step 308 (step 110), the outer wall in consideration of the slope and thickness of the wall object 310 and the wall object 312 Based on the line and the inner wall line, a wall object is connected (step 112) that connects the encounter points of the previous wall object and the added wall object. At this time, the object 316 and the object 318 will have the connection information between each other. At this time, the object 316 and the object 318 having a connection portion 314 as shown in Figure 3b has the connection information between each other, this is to find a wall forming a closed curve in the process of creating a room to be described later floor and ceiling It is used to make

Use

Next, the room making process (step 14) will be described. 7 shows step 14 of FIG. 1 in more detail. When the user clicks on a predetermined room making button prepared on the work screen (step 140), places the mouse cursor on the desired room position and clicks (step 142), the cursor displayed at the clicked position as shown in FIG. The wall object 804 closest to 802 is selected (step 144). The wall object is selected from a pre-stored object library, which can store not only windows and doors but also objects such as sofas, tables, and various upholstery as well as interior attachments such as back boxes and moldings. Next, the selected wall object is used to find whether there are walls forming a closed curve using connection information with other walls of the wall object (step 146). In other words, it consists of a closed curve to check if the window can be placed.

If the connected walls form a closed curve so that the corresponding windows can be placed, when the floor 910 and the ceiling 912 are created in the interior 904 of the connected walls 902 using the connected walls as shown in FIG. The room height 914 is determined in consideration of the floor height and the wall height, configured to be a triangular face 916, and a 3DS file is created (step 148) using the constructed 3D points and triangle face. In this process, 3DS files are created for the walls and walls by creating ceilings and floors.

(step 148_02). In the conversion, 2D data is generated as 3D data by referring to the specified wall height and floor height. When generating the 3D data, as shown in FIG. 11, the floor height 1108 is added to the wall height 1106 when the 3D data 1104 is generated based on the 2D data 1102. Next, when converting, the surface constituting the wall is configured to be a triangular face. When making a triangular face, it is checked whether a window (door) is installed in each wall (step 148_04), and when it is confirmed that the installed window is installed Remove the vertices present in the door (step 148_06) and construct a new triangular face using the remaining vertices and the window (door) vertices (step 148_08). When there are no windows (doors) on the wall, a triangular face is created as shown in FIG. 12A, and when there are windows (doors) 1202, a triangular face is created as shown in FIG. 12B. Next, a 3DS file is created using the three-dimensional coordinates of the wall and the triangular face (step 148_4). In step 148_6, a 3DS file of walls is generated, and a ceiling and a floor are made using the largest value of each wall constituting the room, the ceiling height and floor height entered when the room is created, and the ceiling height entered is set. If it is larger than the height of the highest wall, it does not make a room.

On the user's screen, mesh and mapping are performed at the same time, and the actual image rendered by various techniques such as lighting and camera is immediately displayed.

At this time, each point of the CAD processing is connected with fine lines, and a new object represented as a curve, a circle, or an arc on the screen is created, and a part expressed in each layer is based on a plurality of layers. It is more preferable that the two-layer structure can be represented and designed so that two layers can be connected and the two-layer structure can be designed and expressed.

This process repeats thousands or tens of thousands of loops per second to show the change of objects. When the user clicks the left, middle, or right button of the mouse, the object is placed in accordance with a predetermined convention, moving in the process of placing an object (step 1506), and ending object placement (step 1508). ), Start of change of the object (step 1510), object placement and change operation (step 1512), and object animation value setting 1514.

According to the result of the steps 1502, ..., 1514, the screen movement is performed. If the selection mode is not in the selection mode, the screen movement is performed. Since the two-dimensional movement is impossible, the mode returns to the selection mode.

In addition, if a task for object animation is given, this process performs playback drive processing for object animations such as casement animation, swing door animation, and secretary animation. , To move the screen.

During the screen movement process, collision checking between the camera and the object is performed, the screen movement process is limited by limiting the camera movement direction, and the screen movement is performed according to the camera angle. In addition, a process for preventing camera movement during camera automatic playback (step 1520), and an appropriate menu may be provided, and object animations such as day and night effect functions may be performed according to lighting object movement. This process allows you to see the results in real time by indicating changes in objects, repeating thousands to tens of thousands of loops per second. Such playback data may be stored, and the stored data may be played back in a camera animation (step 1530).

Next, the entire simulation can be supplemented with navigation and real-time three-dimensional data correction (step 16), and the estimate data can be processed (step 18) based on real-time data.
