[Max] Tutorials & Guides / Quick and easy: Fulldome production with Corona, PTGUI basic and FFMPEG
« on: 2016-08-10, 17:48:47 »
Hi guys
if you have ever asked yourself how to produce 180° renderings images in azimuthal equidistant fisheye / domemaster / circular fisheye projection for the use in a planetarium this is the way to go:
1. Render your scene with the CoronaCamMod in spherical override mode
Render "region selected" to save time. You're only needing the middle of the render anyway.
(see attachment 1)
2. On to PTGUI (you don't need the pro version)
- import your renderings
- see attachment 2 for lens settings (should be this way on default)
- panorama settings are: circular fisheye with 180° / 180° (attachment 3)
- render your images in your desired format/resolution (attachment 4)
See attachments "corona_1k" and "mRay_1k" for comparison - it fits! mRay_1k was rendered using the domemaster3D plugin for 3dsMax / Maya which is widely used by dome producers.
3. now there's an easy command in FFMPEG to render the video if you need to
input%03d.jpg specifies the name-format of the input pictures. so in this case, it's 3 digits ( input000.jpg, input001.jpg, ...)
If you happen to have an HTC Vive (or another HMD) like me you then can model a virtual planetarium for your productions to test in VR (tell me if you're interested in a tutorial how to manage this :) )
I hope this helps someone! :)
