Lightfield Viewer lets you examine lightfield images taken with plenoptic cameras.
It automatically computes initial parameters (microlens offset and stride) as a starting-point for tweaking the individual image. As it utilizes the processing power of the GPU by using a highly optimized OpenCL-based rendering-path, results of parameter-changes can be seen in real-time. Final images can be saved in the PNG-format.
The parameters have the following meaning:
|View-Plane Z||The z-position of the virtual sensor plane. Controls the focus-point.|
|Aperture-Size/Z||The ratio of the virtual aperture-size and the distance of the virtual aperture from the virtual sensor plane.|
|Aperture-Z||The logarithmic distance of the aperture from the sensor plane.|
|The x/y-offset of the virtual aperture.|
|The x/y-offset of the first microlens-tessera in pixels relative to the upper left corner of the input-image.|
|The x/y-period-length of the microlens-tesserae in pixels.|
|The relative x/y-crop-factor of the microlens-tesserae. 1 means no crop at all. 0.5 means maximum crop.|
