Stereoscopic conversion for shader based graphics content

摘要

The example techniques of this disclosure are directed to generating a stereoscopic view from an application designed to generate a mono view. For example, the techniques may modify source code of a vertex shader to cause the modified vertex shader, when executed, to generate graphics content for the images of the stereoscopic view. As another example, the techniques may modify a command that defines a viewport for the mono view to commands that define the viewports for the images of the stereoscopic view.

主权项

1. A method comprising:
receiving, with a processor, instructions for a vertex shader that is configured to generate an image of a mono view and that is to be executed on a shader processor of a graphics processing unit (GPU); modifying, with the processor, the instructions of the vertex shader to include one or more instructions that cause the vertex shader, when executed on the shader processor of the GPU, to generate graphics content for a first image of a stereoscopic view after a first execution of the vertex shader, and graphics content for a second image of the stereoscopic view after a second execution of the vertex shader; issuing, with the processor, a command that defines a viewport for the image of the mono view; and subsequent to issuing the command, modifying, with the processor, the issued command that defines the viewport for the image of the mono view to a first command, for a fixed-function unit of the GPU that is different from the shader processor, that defines a viewport for the first image, and a second command, for the fixed-function unit of the GPU, that defines a viewport for the second image.
