Yup, it's the correct image. The curve (Upper 2/3rd of the picture is a single Quad with the curve applied as a texture (Generated using 2D picture controls BTW) The middle part (The comour bar with varying intensities) was prohibitively expensive to redraw with traditional 2D picture control. Therea re a fixed number of pixels on the detector (in this case it was 256) but the scaling and interpolation coupled with the vertical stretching of the colours was very time consuming on a 2D control. With the 3D picture control it was lightning fast. It was a simple input of 256 Colour values (which need to be modified for intensity) and OpenGL does the rest. The botton part (The numbers) is, similarly to the upper part simply a Quad with a texture (which was again generated with the traditional 2D picture controls) applied. Both the upper and lower parts were sufficiently fast to redraw with the 2D picture control (and subsequently applied to the 3D picture). The middle part (The coloured part) was not. Shane.
