With the method for generating a slide show in harmony with music, the user is able to compose an attractive and interesting slide show by a convenient and simple method. The steps of the method comprises: analyzing audio data to obtain reference points, wherein the reference points include at least one beat point of said audio data; obtaining image effects for images; selecting at least one first level point and at least one second level point from the reference points; and composing a slide show of the images with the image effects in association with the audio data, wherein the image effects are controlled according to the first level point and the displaying of the images is controlled according to the second level point.

Method for generating a slide show with audio analysis

A method is for producing the bump mapping effect for a 3D object in a computer graphic. First, a shading vector is produced at one point of the surface of the 3D object. A shift coordinate with respect to this point is determined, according to the shading vector. According to the shift coordinate, a rotational calculation matrix is set up. Then, a diffuse color value with respect to this point is computed, which is equal to the difference between an adjacent rotation color value to this point and an averaged color value, wherein the averaged color value is defined as the sum and average of the color channels for R, G, and B with respect to this point, and the adjacent rotation color value is defined as a sum of the averaged color value with respect to a number of the adjacent points and the coefficient product with respect to the adjacent points in the rotational calculation matrix. Then, the emboss image value at this point is computed. The color channels of R, G, and B of the emboss image value are respectively equal to the product of the color channels of R, G, and B at this point being subtracted by the diffuse color value and the coefficient of the emboss effect. By repeating the foregoing steps, the emboss image value at each point of the surface of the 3D object is computed.

Method for producing bump mapping effect for a three dimensional object of a computer graphic

A method for an image-based rendering of light in a virtual volume is disclosed, which can provide various lighting effects in the two-dimensional image of a three-dimensional object. Furthermore, the virtual light source can be located at any position corresponding to the three-dimensional object. The light sources in the image are divided into two groups, i.e., the light sources in the rear of the three-dimensional object and the light sources in the front of the three-dimensional object. Then, each image for the illuminating effects of the light sources in the rear of the three-dimensional object is merged in sequence. The merged image of all of the light sources in the rear of the three-dimensional object is merged with the image of the three-dimensional object. Thereafter, each image for the illuminating effects of the light sources in the front of the three-dimensional object is merged in sequence. The merged image of all of the light sources in the front of the three-dimensional object is provided with various effects by calculation with special functions. The merged image having various effects is finally merged into the merged image of the image for the illuminating effects of the light sources in the rear of the three-dimensional object and the image of the three-dimensional object to accomplish the image-based rendering of light for the three-dimensional object.
