Controlled dynamic detailing of images using limited storage
Examples of memory-efficient techniques for dynamically generating images having customizable image portions are disclosed herein. In particular embodiments, a collection of contributing images with different image information in the contributing image's channel layers is used to generate a composite result image. By combining the subimage data from each channel of the contributing image in accordance with a composite image function, a resultant composite image can be generated that has the desired customized properties selected by the user. To create the customized properties, one or more of the color channel subimages can have their values scaled (e.g., using matrix multiplication) according to the customization preferences of the user such that, when combined with the other contributing images, the desired customized result is presented to the user.
1. A system, comprising:
a memory or storage device; and
one or more processors, the one or more processors being configured to generate composite image data for a composite image by:
receiving data indicating a request for a color on a customizable portion of a composite image; and
generating composite image data for displaying the composite image from two or more contributing images, the contributing images including a first contributing image with base image information, and a second contributing image with customizable color information, the second contributing image further having one or more color channel subimages, each color channel subimage having dynamically customizable image data for one or more customizable portions of the composite image,
wherein the generating further comprises altering the dynamically customizable image data of one or more of the color channel subimages of the second contributing image responsive to the received user selection, thereby reducing memory overhead by dynamically generating the composite image data without using a pre-rendered image incorporating the received user selection.
2. The system of claim 1 , wherein the generating the composite image data is performed in part by applying a scaling factor to the image data values of one of the color channel subimages.
3. The system of claim 2 , wherein the scaling factor comprises a 1×3 or a 1×4 vector that is matrix multiplied with the image data values of the one of the color channel subimages.
4. The system of claim 3 , wherein the one or more processors are further configured to determine the scaling factor based on the received user selection.
5. The system of claim 1 , wherein each of the color channel subimages defines a different customizable portion of the composite image.
6. The system of claim 1 , wherein one or more of the color channel subimages comprise image data values that do not visually contribute to the composite image.
7. The system of claim 1 , wherein the contributing images further comprise a third contributing image with lighting information.
8. The system of claim 1 , wherein the request for a color is received from a client computer executing a web browser, and wherein the method further comprises transmitting data corresponding to the composite image data to the client computer for display via the web browser.
9. One or more memory or storage devices storing computer-executable instructions, which when executed by a compute cause the computer to perform a method, the method comprising:
receiving data indicating a request for a color on a customizable portion of a composite image; and
generating composite image data for displaying the composite image from two or more contributing images, the contributing images including a first contributing image with base image information, and a second contributing image with customizable color information, the second contributing image further having one or more color channel subimages, each color channel subimage having dynamically customizable image data for one or more customizable portions of the composite image,
wherein the generating further comprises altering the dynamically customizable image data of one or more of the color channel subimages of the second contributing image responsive to the received user selection, thereby reducing memory overhead by dynamically generating the composite image data without using a pre-rendered image incorporating the received user selection.
10. The one or more memory or storage devices of claim 9 , wherein the generating the composite image data is performed by applying a function that dictates how the two or more contributing images are to be combined and how the dynamically customizable image data of the one or more of the color channel subimages of the second contributing image is to be scaled responsive to the received user selection.
11. The one or more memory or storage devices of claim 9 , wherein the generating the composite image data is performed in part by applying a scaling factor to the image data values of one of the color channel subimages.
12. The one or more memory or storage devices of claim 9 , wherein each of the color channel subimages defines a different customizable portion of the composite image.
13. The one or more memory or storage devices of claim 9 , wherein one or more of the color channel subimages comprise image data values that do not visually contribute to the composite image.
14. The one or more memory or storage devices of claim 9 , wherein the contributing images further comprise a third contributing image with lighting information.
15. The one or more memory or storage devices of claim 9 , wherein the request for a color is received from a client computer executing a web browser, and wherein the method further comprises transmitting data corresponding to the composite image data to the client computer for display via the web browser.
16. A system, comprising:
a memory or storage device; and
one or more processors, the one or more processors being configured to generate composite image data for a composite image by:
receiving data indicating a request for a color on a customizable portion of a composite image; and
generating composite image data for displaying the composite image from two or more contributing images, the contributing images including a first contributing image with base image information, and a second contributing image with customizable color information, the second contributing image further having one or more color channel subimages, each color channel subimage having dynamically customizable image data for one or more customizable portions of the composite image,
wherein the generating the composite image data is performed by applying a function that dictates how the two or more contributing images are to be combined and how the dynamically customizable image data of the one or more of the color channel subimages of the second contributing image is to be scaled responsive to the received user selection.
17. The system of claim 16 , wherein the generating the composite image data is performed in part by applying a scaling factor to the image data values of one of the color channel subimages.
18. The system of claim 16 , wherein one or more of the color channel subimages comprise image data values that do not visually contribute to the composite image.
19. The system of claim 16 , wherein the contributing images further comprise a third contributing image with lighting information.
20. The system of claim 16 , wherein the request for a color is received from a client computer executing a web browser, and wherein the method further comprises transmitting data corresponding to the composite image data to the client computer for display via the web browser.
