Fullest featured web 3d / AR viewer
P3d.in, although this Appsumo campaign page isn't actually called p3d.in which could be confusing, is probably the fullest featured 3d / AR editor and viewer I've experienced. The UI/UX is simple, but the product is extremely powerful.
I'm 20 years in the 3d and animation industry working with some of the largest brands, have spent time teaching 3d games design over the years and began working with AR many many years ago so have a lot of experience with 3d in general and with online viewers / technology.
Its quite amazing that this viewer has PBR (Physical Based Rendering) which means more realistic materials on the 3d models in addition to HDRI images for amazing reflections and lighting from the images as well as up to 8k texture sizes for great resolution.
P3d.in really packs a punch.
I've worked on client projects over the years to produce 3d models viewable online and p3d.in will really cut down development time, especially if you want all these features mentioned above. Essentially you can create 3d experiences for your clients (and their customers) in a fraction of the time and cost.
If you think your clients will need interactive 3d experiences for their products (the way the web is going), grab this deal now!
