Elite Exhibits Posted June 18, 2015 Share Posted June 18, 2015 Would like to make a custom HDRI Background of a specific venue What software is needed for this ? Photoshop or ? - Thanks Peter Quote Link to comment
rDesign Posted June 19, 2015 Share Posted June 19, 2015 By 'background' do you mean a 360 degree spherical HDRI that you can use to illuminate a 3d model? If so, unfortunately it's not the simplest of tasks. Here's a link with suggested step-by-step that I found by googling 'create spherical hdri map': Adaptive Samples :: How to Create Your Own HDR Environment Images Step #5 (assuming you get through #1-4) applies to Blender, which you can ignore since you would be using Vectorworks. The correct projection for the RW background HDRI is 'Equirectangular', which has proportions of 2:1 (eg. 3000px wide by 1500px high). Software-wise, unless you already own a recent version of Photoshop, I would recommend using PTGui Here's a link to a tutorial on creating HDRI Panoramas with PTGui Good Luck! Quote Link to comment

Kaare Baekgaard Posted September 22, 2015 Share Posted September 22, 2015 With VW 2016 you can now do a 'cheat version' of HDRI, that only requires a regular panorama image, that you can create with most smartphones. Any image can now be mapped onto the background 'sphere' regardless of its proportions. It will automatically be stretched to fit. The resulting panoramic background is similar to a hdri in the sense that it lights the scene and is reflected by objects, but as far as I can see, it does not come close to the dynamic range from highlight to shadow, that a true HDR image has. So I guess the scene would need some extra lights to get sufficient contrast. But still – it is an awesome feature. Perhaps someone has tested this feature more than I and can share additional insights. Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted September 22, 2015 Vectorworks, Inc Employee Share Posted September 22, 2015 (edited) Yes I use Photosphere on my iPhone for this now. Much easier than tracking down actual HDRI panoramas. Here's one from vacation in Savannah: https://www.dropbox.com/s/9g5lggwat580z5x/Savannah%20Photosphere.jpg?dl=0 Edited September 22, 2015 by Dave Donley Quote Link to comment
Vectorworks, Inc Employee Neil Barman Posted December 26, 2016 Vectorworks, Inc Employee Share Posted December 26, 2016 Related to this subject... I've found a collection of HDRI backgrounds, each at a variety of resolutions (256p, 512p, 1k, 2k, 4k, 8k, 16k). Which resolutions are best used in Vectorworks? Which resolutions would be beyond what Vectorworks can handle or are beyond what would be appreciable? Thanks! -Neil Quote Link to comment
Markvl Posted March 10, 2017 Share Posted March 10, 2017 By the way @NeilBwhere did you find that collection of HDRI backgrounds? Quote Link to comment
