Problems solved by technology

[0008] Aiming at the problem in the prior art that the 3D model is easily blocked and cannot be displayed or operated due to different viewing angles, which increases the user's operating cost and brings inconvenience to the user's operation, a 3D model rendering system that reduces the occlusion of close-range objects is provided. and a rendering method, the rendering system can zoom out or translucently display or hide the 3D model closer to the eyes according to the change of the viewing angle, so as to avoid mutual occlusion between the models, thereby reducing the user's operation cost and expanding the user's field of vision , to enhance the user simulation experience

Embodiment 1

[0050] A 3D model rendering system for reducing close-range object occlusion in this embodiment includes a view angle capturer, a forced display controller, a display sign controller, and a model renderer, such as figure 2 As shown, among them,

[0051] The angle of view catcher logically classifies different angles of view to form different angles of view states. In this embodiment, this classification includes God's angle of view and roaming angle of view, that is, the angle of view state includes God's angle of view and roaming angle of view, such as figure 1 As shown, taking the 3D model of the living room as an example, when the viewing angle is outside the 3D living room model, it is the God’s viewing angle (viewing angle A), and when the viewing angle is inside the living room 3D model, it is the roaming viewing angle (viewing angle B); the viewing angle catcher captures the viewing angle in real time Change between different classifications, and transmit the viewing a...

Embodiment 2

[0058] A kind of 3D model rendering method that reduces the occlusion of close objects in this embodiment, utilizes the rendering system in Embodiment 1, such as figure 2 with image 3 shown, including the following steps:

[0059] Step 1. Initialization of view classification;

[0060] The angle of view catcher logically classifies different angles of view to form a angle of view state. In this embodiment, this classification includes a God's angle of view and a roaming angle of view, that is, the angle of view state includes a God's angle of view and a roaming angle of view, such as figure 1 As shown, taking the 3D model of the living room as an example, when the viewing angle is outside the 3D model of the living room, it is the perspective of God (viewing angle A), and when the viewing angle is inside the 3D model of the living room, it is the viewing angle of roaming (viewing angle B). The classification value of the viewing angle state Including integer type, characte...

Embodiment 3

[0076] A kind of three-dimensional model rendering method that reduces the occlusion of close objects in this embodiment is basically the same as Embodiment 2, the difference is that the specific process of step 2 in this embodiment is as follows:

[0077] According to the logical classification of step 1, under different viewing angles, the display sign controller initializes the control display signs of the 3D model respectively to form a control display sign table of the 3D model; wherein the control display signs include "normal", "zoomed out", "Hidden" and "translucent", the information of the control display mark table includes the viewing angle state, the 3D model, and the control display mark. The initialization of the 3D model control display mark table is added as an automatic marking method, specifically: according to the God's perspective and the roaming perspective respectively The classification of the 3D model takes the carrier of the 3D model as the identificati...

Abstract

The invention discloses a three-dimensional model drawing system and method for reducing short-range object shading, and belongs to the field of three-dimensional model design. The three-dimensional model drawing system comprises a visual angle catcher, a forced display controller, a display marker controller and a model renderer; the visual angle catcher is used for logically classifying different visual angles and catching changes in the visual angle; the forced display controller controls on / off state of a forced display switch; the display marker controller is used for adding control display markers to models at different visual angles, calculating corresponding drawing states of three-dimensional models according to the visual angle state and forced display switch state, and transmitting to the model renderer; the model renderer controls drawing of the three-dimensional models. The three-dimensional model drawing method can provide narrowed displaying or semitransparent displaying or hiding for short-range three-dimensional models according to the changes in visual angles, inter-model mutual shading is avoided, operation cost is reduced accordingly, visual field is extended for a user, and user experience on simulation is improved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional model design, and more specifically, relates to a three-dimensional model rendering system and a rendering method that reduce the occlusion of close objects. Background technique [0002] With the strong pursuit of people's desire for a more realistic virtual reality experience, the virtual reality technology of three-dimensional models has also become popular. Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. Immerse yourself in that environment. [0003] 3D model processing is a very important operation in the fields of computer graphics, computer entertainment, and computer-aided design. There are a large number of models and terrains to be drawn in large-scale 3D scenes, most of which are non-transparent. During the actual operation of 3D models, due to different...
