Supplementary Data: QtVolView

The QtVolViewLITE program is designed to run on any PC with a 64 Mbyte graphic card. It is suitable for viewing the data shown in Figures 1A and 2A as colour OPT volume and section views of the Antirrhinum flower. Internal floral structures such as anther lobes and the ovary at the base of the carpel are revealed. Three OPT scan channels are visible.  Transmission (shown in blue), endogenous fluorescence, Leica TXR filter (shown in red) and GFP fluorescence, GFP1 filter (shown in green).

The data can be viewed interactively as a volume from different angles and as virtual sections. The volume can be clipped to reveal internal structures. See the Quick Start pdf. The full QtVolView program uses more specialised graphic card features and is available on request.

Top row; volume view of mature ATHB8:GUS Arabidopsis leaf with stained veins (m2, 9 dfs) displayed using QtVolView lighting and tone-shader effects. Middle row; combined transmission and fluorescent (GFP1) OPT channels. Visible channel is red, fluorescent channel is green. Bottom row; stained veins extracted using semi-automatic segmentation tools. In the application the leaf can be viewed from any angle, re-coloured, etc.
