Abstract
The invention discloses an image rendering method applied to a computer screen, comprising the following steps: (1) a window for supporting a transparent channel is created; (2) display coordinates of each pixel in the image are computed, a three-dimensional accelerated graphics port is used for amplifying the image and rendering the image to a local video memory mapping, and background color is set into black ARGB; (3) chromatic values of a plurality of adjacent points in the image are averaged, and the rendered mapping is zoomed into output size; (4) the mapping in the local video memory is exchanged to an internal memory mapping by the operation of the three-dimensional accelerated graphics port:; (5) a two-dimensional Alpha mixed function is used for leading the internal memory mapping to be drawn on a desktop, so as to lead the image to be displayed on the desktop. The method can realize that three-dimensional cartoon images can be rendered out clearly and smoothly in a real-time manner on any desktop background, thereby achieving good expressive form, eliminating sawtooth form at the edge part of the three-dimensional image, leading the image display to be real and achieving smooth transition effect.
Description
Technical field
The present invention relates to the computer image processing technology field, particularly a kind of image rendering method that is applied to computer desktop.
Background technology
The desktop of computing machine is different and present the color of numerous and complicated along with background or the window opened, and a three-dimensional cartoon image is wanted to be independent of window and shown, just must can adapt to different background colors.Traditional 3D rendering model rendering method is to use three-dimensional picture accelerating interface (as Direct3D), directly image is rendered on the screen.Because this method only supports rectangle to play up, and be directly video memory to be operated, do not play up flow process, so be not suitable for playing up polygonal desktop picture through two dimension.
General method, for example create the method for supporting the transparent channel window: (1) is set as a window of supporting transparent channel to window when creating the use window, this window is by being provided with the transparent channel value of different pixels point, the Alpha that this pixel and the same position pixel color of bottom background are done in various degree mixes, thereby supports translucent playing up; (2) use the three-dimensional picture accelerating interface by the conventional method rending model, the background color of playing up is set to black; (3) paint on the window with the two-dimensional graphics interface, again the background color of window is arranged to transparent black, at this moment, all black parts will hollow out, reaches the purpose of drawing polygonal window.
The defective of said method is, because in the time of three-dimensional rendering, the three-dimensional picture accelerating interface is not supported translucent, even and the whole figure that causes exporting is having under the situation of supporting the transparent channel window, still can not just mix with background colour, particularly the part at edge has tangible sawtooth sense.Simultaneously, because sawtooth can appear in the person model that utilizes the three-dimensional picture accelerating interface directly to play up out, visual effect is not ideal, and relatively poor with the fusion of background on the table, makes sawtooth show more obviously.
Summary of the invention
Based on the defective that exists in the prior art, the object of the present invention is to provide a kind of 3-D view rendering intent that can effectively merge display image and desktop background, to eliminate the crenellated phenomena of display image marginal portion.
The technical solution adopted in the present invention: a kind of image rendering method that is applied to computer desktop may further comprise the steps:
(1) creates a window of supporting transparent channel;
(2) calculate the displaing coordinate of each pixel in the image, this image is amplified and play up to the video memory pinup picture with the three-dimensional picture accelerating interface, background colour be made as into black ARGB (Alpha, Red, Green, Blue);
(3) to the color-values calculating mean value of plurality of adjacent points in the image (adjacent selection of counting is associated with enlargement factor in the above-mentioned steps (2)), and the pinup picture after will playing up zooms to the output size;
(4) by the operation of three-dimensional picture accelerating interface the pinup picture in the video memory is exchanged on the internal memory pinup picture;
(5) use two-dimentional Alpha mixed function that the internal memory pinup picture is painted on the desktop, image is shown on the desktop.
Image magnification ratio in the above-mentioned steps (2) is 2 times, the length of the image after promptly amplifying and the length that width is original image and the twice of width.
Background colour in the above-mentioned steps (2) is black ARGB (255,255,255,255).
The mean value of the color-values of image is to come calculating mean value with adjacent color-values at 4 in the above-mentioned steps (3), and its account form is:
Pv＝ARGB(p
a，p
r，p
g，p
b)
p
a＝(s1

g+s3
g+s4
g)/4
p
b＝(s1
b+s2
b+s3
b+s4
b)/4
Wherein: s represents the source color, and p represents color of object.
Two-dimentional Alpha mixed function in the above-mentioned steps (5) is:

Wherein: d represents screen color, and k represents background color, and color is played up in the i representative.
The present invention can realize with the three-dimensional cartoon image no matter can be clear under any desktop background, mellow and full ground real-time rendering comes out, reach a good form of expression, eliminated the zigzag fashion of 3-D view marginal portion, it is truer to make that image shows, reaches the effect that seamlessly transits.

Fig. 3 is the convergent-divergent pinup picture synoptic diagram in the image rendering method step of the present invention (3).
Embodiment
Below in conjunction with accompanying drawing concrete structure of the present invention is further described.
As shown in Figure 1, 2, the method played up of image of the present invention realizes by following steps:
(1) creates window: create a window of supporting transparent channel, can be Alpha with desktop and mix.
(2) rendering image: calculate the displaing coordinate of each pixel in the image, this image is amplified and play up to the video memory pinup picture with the three-dimensional picture accelerating interface, background colour is made as into black ARGB (255,255,255,255); The length of the image after the amplification and width are the length of original image and the twice of width, that is:
H＝2h
W＝2w
Wherein: H, W are length (highly) and the width of playing up pinup picture; H, w are original length (highly) and width.
(3) convergent-divergent pinup picture: the pinup picture after will playing up zooms to the output size, reach anti-sawtooth effect, in this process by with the effect that transparent channel is arranged, by to color-values calculating mean value adjacent 4 in the image, the every bit that convergent-divergent comes out all can correspondingly have a transparent value, as shown in Figure 3.
