Improving the floating 3D annotation and getting it on the iPad

I’ve been working lately on improving the solution for floating 3D annotations.

Currently I’ve attached to each floating annotation a small rectangle where the text will fit in. The rectangle is automatically resized based on the text size. Also currently it is possible to filter the 3D annotations based on the camera position up to 8 separate areas (and it could be easily increased if needed). For example, if we have a huge object that a simple planar projection (planar means: showing annotations for the front and the back of the model based on user’s position with respect to the model) for displaying 3D annotations is not sufficient; we can make up to octagon projection of annotations  so the user will see floating annotations on one of the 8 sides of the 3D model, depending on the user’s position with respect to the 3D model.

Furthermore, another feature is added, which is automatically resize the annotations based on model’s size. The screenshot below is from the iPad while experimenting with one of the 3D models in our library.

Improving 3D annotations

Currently I’m rewriting/improving the tool for placing the annotation on the 3D objects.
