Claim:
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.
