Abstract:
A computerized method for stereoscopically and seamlessly imaging on a generally cylindrical screen, the method comprising:configuring imaging data for a plurality of selectable sub-screens encompassing the cylindrical screen each sub-screen comprising a plurality of selectable strips axially extending relative to a corresponding sub-screen in the cylindrical screen; rendering two channels of imaging data increments for each strip based on a parallax model with a reference line selectively rotatable to be in parallel alignment relative to each respective plane defined by each strip; rectifying the imaging data for each corresponding sub-screen by re-rendering said imaging data relative to a computer-synthesized cylinder configured as the cylindrical screen, and texture-mapping the originally rendered sub-screen imaging data on the computer-synthesized cylinder to generate new sub-screen imaging data substantially free of distortion; combining each imaging data increment corresponding to each strip in a respective sub-screen to generate stereoscopic imaging data for that respective sub-screen; and combining each sub-screen imaging data to generate stereoscopic imaging data substantially encompassing the annular span of the cylindrical screen.
