Abstract

Display filters, including color filters, can be enabled in collaborative environments. When a user of an end user device desires to have a color filter applied, a windowing system or other source of graphics data can render a frame via a graphics driver. Once the frame is rendered, the graphics driver can enable a collaboration tool to capture the frame and share it via a collaboration solution. Separately from the rendering of the frame, the windowing system can leverage a color filter module to directly apply a color filter to the frame. Once the color filter is applied, the windowing system can cause the frame to be displayed locally. Because the graphics driver is not used to apply the color filter, the color filter will not be applied to any frame that the collaboration tool captures and shares.

Claims (33)

1. A method for enabling display filters in collaborative environments, the method comprising:

rendering, via a graphics driver, graphics data to a framebuffer object to define a frame to thereby enable a collaboration tool to capture and share the frame via a collaboration solution;

after the frame is rendered to the framebuffer object and captured by the collaboration tool, causing a color filter to be directly applied to the frame defined in the framebuffer object rather than being applied via the graphics driver; and

after the color filter has been directly applied to the frame defined in the framebuffer object, causing the frame to be displayed locally.

2. The method of claim 1 , wherein the graphics driver is an OpenGL graphics driver.

3. The method of claim 1 , wherein the method is performed by a windowing system.

4. The method of claim 1 , wherein the method is performed by an application.

5. The method of claim 1 , wherein the graphics driver comprises a runtime.

6. The method of claim 1 , wherein causing the color filter to be directly applied to the frame defined in the framebuffer object rather than being applied via the graphics driver comprises interfacing with a color filter module to cause the color filter module to apply the color filter to the frame without using the graphics driver.

7. The method of claim 1 , wherein causing the frame to be displayed locally comprises swapping the framebuffer object.

8. The method of claim 1 , further comprising:

determining that a policy dictates that the color filter should be applied to the frame.

9. The method of claim 8 , wherein determining that the policy dictates that the color filter should be applied to the frame comprises determining that the policy is applicable to a currently logged in user.

10. The method of claim 1 , wherein the frame defines a window or a desktop.

11. The method of claim 1 , wherein each of the frames defines a window or a desktop.

12. One or more computer storage media storing computer executable instructions which when executed implement a method for enabling display filters in collaborative environments, the method comprising:

repeatedly rendering, via a graphics driver, graphics data to a framebuffer object to define frames to thereby enable a collaboration tool to capture and share the frames via a collaboration solution;

after each of the frames is rendered to the framebuffer object and captured by the collaboration tool, causing a color filter to be directly applied to the frame rather than being applied via the graphics driver; and

after the color filter has been directly applied each of the frames, causing the frame to be displayed locally.

13. The computer storage media of claim 12 , wherein the method is performed by a windowing system.

14. The computer storage media of claim 12 , wherein the method is performed by an application.

15. The computer storage media of claim 12 , wherein causing the color filter to be directly applied to each of the frames rather than being applied via the graphics driver comprises interfacing with a color filter module to cause the color filter module to apply the color filter to each of the frames without using the graphics driver.

16. The computer storage media of claim 12 , wherein causing each of the frames to be displayed locally comprises swapping the framebuffer object.

17. The computer storage media of claim 12 , wherein the method further comprises:

determining that a policy dictates that the color filter should be applied to each of the frames.

18. The computer storage media of claim 17 , wherein determining that the policy dictates that the color filter should be applied to each of the frames comprises determining that the policy is applicable to a currently logged in user.

19. An end user device comprising:

one or more processors; and

computer storage media storing computer executable instructions which when executed implement a method for enabling display filters in collaborative environments, the method comprising:

rendering, via a graphics driver, graphics data to a framebuffer object to define a frame to thereby enable a collaboration tool to capture and share the frame via a collaboration solution;

after the frame is rendered to the framebuffer object and captured by the collaboration tool, causing a color filter to be directly applied to the frame defined in the framebuffer object rather than being applied via the graphics driver; and

after the color filter has been directly applied to the frame defined in the framebuffer object, causing the frame to be displayed locally.

20. The end user device of claim 19 , wherein causing the color filter to be directly applied to the frame rather than being applied via the graphics driver comprises interfacing with a color filter module to cause the color filter module to apply the color filter the frame without using the graphics driver.
