Embodiment Construction

[0028] A light and shadow tracking method for a spatial two-dimensional image of the present invention will be described in detail below in conjunction with a specific embodiment, including:

[0029] 1. Generate the wireframe of the perspective space on the plane, as shown in Figure 1, including the first plane 1, the second plane 2, the third plane 3 and the fourth plane 4 perpendicular to the first plane, and the first plane Parallel fifth plane 5, sixth plane 6 intersecting fifth plane 5, fourth plane 4 and second plane 2;

[0030] 2. First select the wireframe range of the first plane 1 in the space, create a new layer in this area and fill it with a color. The color is consistent with the color of the wall in the actual space, and this layer is a natural color layer;

[0031] 3. Create a new square area layer and fill it with a black translucent layer with a gradient effect, the transparency is 40%--20%, and distort this layer according to the wireframe range of the first...

Abstract

A ray tracing method of two-dimensional images in space is used to simulate three-dimensional space in two-dimensional space. The three-dimensional space has five faces of a first plane, a second plane intersects with the first plane, a third plane, a fourth plane and a fifth plane which is parallel to the first plane. The method comprises selecting one area on the first plane to fill the actual color of the plane to serve as a natural color layer, superposing a grey scale layer on the natural color layer of the first plane, superposing an image tracing layer on the grey scale layer of the first plane, superposing an illumination layer on the image tracing layer of the first plane, and the second plane, the third plane, the fourth plane and the fifth plane are superposed in the order of the first plane processing, then jointing the corresponding layers of all planes. The invention can realistically display three-dimensional images in two-dimensional space.

Description

technical field [0001] The invention relates to a light and shadow tracking method for a spatial two-dimensional image. Background technique [0002] Any space is an enclosed or semi-enclosed area composed of different surfaces. The layers contained in each surface in the space include: the natural color layer used to display the color of the surface itself; the spatial hierarchy and A realistic grayscale layer; a ray tracing layer for simulating the influence of other faces on itself; a lighting layer for simulating the distortion of the object's own color caused by lighting, and the effects of other objects on the face The shadow layer formed by the projection, and if the surface has reflection properties (such as marble, metal, mirror, etc.), it needs to express the translucent reflection layer. [0003] In the space of one-point perspective and multi-point perspective expressed by two-dimensional images, the soft diffuse reflection effect formed when the light bounces r...
