A method of horizontal transformation of vertex position from plane game to three-dimensional

Abstract

The invention discloses a novel vertex position lateral shifting method of converting a planar game to a stereo game. After normal projection conversion of every vertex, a novel lateral deviation shift value can be calculated according to the depth value of the converted vertex, and the shift value can be multiplied by a coefficient according to the visual angle number, and then can be added to a previous lateral component x value after the projection conversion process to acquire a new lateral component x'. The parallax error can be reduced by increasing the lateral deviation, which is in accordance with the characteristics of the naked eye 3D screen. The number of the out-of-screen object is less than the number of the in-screen objects, which is in accordance with the out-of-screen and in-screen watching habits, and therefore the feeling of the human eyes watching the world freely can be simulated to the greatest extent, the enough field depth feeling can be guaranteed, the calculation is simple, and the calculated amount can be reduced.

Description

Technical field: [0001] The invention belongs to the technical field of converting a plane game to a three-dimensional, and in particular relates to a method for transversally transforming a vertex position of a plane game into a three-dimensional. Background technique: [0002] The existing method of converting a plane game to a three-dimensional effect is generally: first, the vertex data is transformed from the viewpoint, and by modifying the camera position, the original camera position is moved to the left or right by a position or angle; then the model is transformed, and the objects in the scene The vertices of the model move to the desired position after model conversion, and then perform operations such as viewpoint positioning on the scene. The model conversion and viewpoint conversion together constitute the model view matrix; then perform projection transformation to reduce the dimensionality (projection transformation is similar to selecting a camera lens) to ge...

Problems solved by technology

This method cannot linearly modify the moving distance of the object, resulting in poor three-dimensional effect, and there is no contrast between the effect of going out of the screen and entering the screen. Generally, there is no way out of the screen.

[0003] Another method is the 3D method of wearing glasses, using a curve formula to describe the offset of the object moving to the left or right. The limitation of this method is that it is not applicable on the naked-eye 3D screen, and the parallax in the distance is too large. Part of it will produce ghosting on the naked-eye 3D screen (generally, the naked-eye 3D screen has a tolerance for parallax)

In addition, the screen close to the observer will have a large parallax, making the menu or options unclear
