Abstract
A rendering apparatus provides, with respect to a defined viewer location and a defined viewport, a desired rendering of objects defined by object data having an object data format, in a three-dimensional object space. The apparatus may have a graphics accelerator for transforming object data into image data determined with respect to the defined viewer location and the defined viewport. The apparatus also may have a rendering processor for first converting at least one parameter characterizing the desired rendering into parameter data in object data format, feeding the parameter data to the graphics accelerator, and then converting resulting image data as to the at least one parameter to a further processed result pertinent to the desired rendering.
Claims
1. A rendering apparatus for providing, with respect to a defined viewer location and a defined viewport, a desired rendering of objects defined by object data having an object data format, in a three dimensional object space, the apparatus comprising: a. a graphics accelerator for transforming object data into image data determined with respect to the defined viewer location and the defined viewport; and b. a rendering processor for converting at least one parameter characterizing the desired rendering into parameter data in object data format, feeding the parameter data to the graphics accelerator, and converting resulting image data as to the at least one parameter to a further processed result pertinent to the desired rendering.
2. A rendering apparatus according to claim 1, further comprising an intermediate memory in which is stored the image data from the graphics accelerator, wherein the rendering processor converts the image data stored within the intermediate memory into the further processed result.
3. A rendering apparatus according to claim 1 , wherein the image data is defined by values associated with a plurality of pixel locations in an image.
4. A rendering apparatus according to claim 3, wherein each of the objects has a surface represented by a plurality of primitive polygons, and the rendering processor, before feeding the object data to the graphics accelerator, utilizes a tag assigned to the primitive polygons, so as to associate by tag pixel locations with primitive polygons.
5. A rendering apparatus according to claim 3, wherein the rendering processor, before feeding the object data to the graphics accelerator, utilizes a tag assigned to each of the objects, so as to associate by tag pixel locations in the image with objects.
6. A rendering apparatus according to claim 5, wherein the rendering processor, as part of converting resulting image data, identifies by tag the portions of object surfaces present in the image, and restricts further processing associated with - 16 - the desired rendering to such portions so as to reduce processing overhead associated with the desired rendering.
7. A rendering apparatus according to claim 6, wherein the tag is a color.
8. A rendering apparatus according to claim 5, wherein the tag is a color.
9. A rendering apparatus according to claim 4, wherein the tag is a color.
10. A method for providing, with respect to a defined viewer location and a defined viewport, a desired rendering of objects defined by object data having an object data format, in a three dimensional object space, the method comprising: a. providing a graphics accelerator for transforming object data into image data determined with respect to the defined viewer location and the defined viewport; b. converting at least one parameter characterizing the desired rendering into parameter data in object data format; c. feeding the parameter data to the graphics accelerator; and d. converting resulting image data as to the at least one parameter to a further processed result pertinent to the desired rendering.
11. A method according to claim 10, further comprising providing an intermediate memory for storing the image data from the graphics accelerator, and wherein step (d) also includes converting the image data stored within the intermediate memory into the further processed result.
12. A method according to claim 10, wherein the image data is defined by values associated with a plurality of pixel locations in an image.
13. A method according to claim 12, wherein each of the objects has a surface represented by a plurality of primitive polygons, and wherein step (b) also includes the step of utilizing a tag assigned to the primitive polygons, so as to associate by tag pixel locations with primitive polygons.
14. A method according to claim 12, wherein step (b) also includes the step of utilizing a tag assigned to each of the objects, so as to associate by tag pixel locations in the image with objects.
15. A method according to claim 14, wherein converting resulting image data includes the step of identifying by tag portions of object surfaces present in the - 17 - image, and restricting further processing associated with the desired rendering to such portions so as to reduce processing overhead associated with the desired rendering.
16. A method according to claim 15, wherein the tag is a color.
17. A method according to claim 14, wherein the tag is a color.
18. A method according to claim 13, wherein the tag is a color.
19. A method for rendering graphics data describing three dimensional objects defined within an object space, the method comprising the steps of: a. selecting a graphics effect which is output resolution dependent; b. rendering the plurality of objects with a two dimensional graphics accelerator, such rendering causing a memory to contain pixel data corresponding to a predetermined output resolution; and c. applying the graphics effect to the pixel data.
20. A graphics rendering program stored on a computer readable medium for providing a desired rendering of objects defined by object data having an object data format, in a three dimensional object space, the program configured so as to be executable by a computer having a two dimensional graphics accelerator for transforming object data into image data determined with respect to a defined viewer location and a defined viewport, the program when loaded into the computer causing the establishment of a rendering apparatus comprising: a. a graphics accelerator for transforming object data into image data determined with respect to the defined viewer location and the defined viewport; and b. a rendering processor for converting at least one parameter characterizing the desired rendering into parameter data in object data foimat, feeding the parameter data to the graphics accelerator, and converting resulting image data to a further processed result pertinent to the desired rendering.
21. A graphics rendering program according to claim 12, wherein the computer further includes an intermediate memory in which the rendering program causes to be stored the image data from the graphics accelerator, and wherein the - 18 - rendering processor converts the image data stored within the intermediate memory into the further processed result.
