AI Technical Summary

Problems solved by technology

However, the current real-time 3D image processing technology cannot reflect the changes in the surrounding environment of the object, cannot display the effects of environmental reflection and refraction on the object, and cannot effectively reflect the changes in lighting conditions in the scene because there is no corresponding processing method for the above-mentioned factors. , so the calculated lighting effect is less realistic

Embodiment Construction

[0030] As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the present invention includes environment input device, scene illumination input device, sky illumination input device, ground illumination input device, model input device, camera position input device, environment Calculator, Scene Lighting Calculator, Environment Lighting Calculator, Texture Memory, A Brightness Memory, B Brightness Memory, Color Vector Adder, Output Device.

[0031] The environmental input device inputs the environmental information at a certain moment, and converts it into a cube map composed of six surfaces. The cube records the color and brightness information of the entire space centered on the object, and these information are stored in the cube environment projection data.

[0032] The scene lighting input device inputs the scene lighting information at a certain moment, and the scene lighting information mainly includes the direction of the scene light source, the brightness of the backgr...

Description

technical field [0001] The invention relates to a real-time three-dimensional image processing device. Background technique [0002] The current real-time 3D image processing technology mainly works on lighting. It calculates the dot product of the model vertex normal vector and the direction of the light source. It is usually called a T&L (Transformation and Lighting) system. The operation is simple and efficient, but the effect is relatively Difference. The factors that affect the image effect are: when the environment around the object changes, the color correspondence of the model will also change; for objects with smooth surfaces, the model will show reflection effects; for transparent or translucent objects, the model will show refraction effects; In different weather (sky and atmospheric lighting) and different ground, the model will present different effects. For example, when the sky is dark or cloudy, the model will be darker, the ground is...
