3-dimensional (3-D) visualizations are a means of adding depth to otherwise 2-dimensional images. For astronomical images, depth is frequently not measured, but relative depth relationships can be inferred. We present a 3-D visualization of a portion of the Carina Nebula imaged with the Hubble Space Telescope.
The source image is a color composite of two datasets obtained with the Advanced Camera for Surveys. Images in the Hα+[N II] filter (F658N) were taken from a 2005 Carina Nebula survey mosaic by Smith et al. (2010, MNRAS, 405, 1153). Images in the [O III] filter (F502N) were obtained by our team in 2010 in parallel to WFC3 observations of the nearby HH 901 region (HST proposal 12050).
A 3-D model was constructed from the color composite image by separating it into several planes. Stars and nebular structures were extracted from the image and placed on different planes in 3-D digital modeling software using morphology of nebular features to infer relative depth. Relief texture was added to some of the nebular structures in the model to further enhance the perception of depth.
For a static image, frames rendered from the 3-D model at two different viewpoints are composited into a single image in anaglyph (red-blue) stereo that will be shown.
