p3d.in VS Shapespark

With Shapespark you can create realistic, web-based walkthroughs and video meetings from your 3D models that can be easily shared via links and opened directly on desktop and mobile.

Main features:

• Full movement freedom. Allow your clients to enter a space and freely walk around to examine every corner and detail. Make them feel as if they are there. Unlike 360 panoramas, the presentation is not limited to a few selected viewpoints and there is no distortion in the corners of the screen.
• 3D Meetings. With a couple of clicks turn any 3D model into a meeting space where people walk & talk in 3D. Participants can use interactive features like screen sharing in the 3D world! Share just as easily as a regular Shapespark walkthrough.
  
• Integrated light-map baking engine with automatic UV unwrapping that allows for realistic lighting without a need for a powerful computer during the presentation, so the result can be viewed even on mobile devices or laptops. To speed up the baking process you can use CUDA enabled graphics card or multiple CPUs.
• Virtual reality support.
• Interactive features. You can place material pickers in your scene to allow the user to change materials and clickable elements in the model to show additional information.
