U3D mesh + point cloud
Posted: Tue 28. Jan 2014, 13:47
Hi,
I am working with the U3D file format for visualizing medical data. I do not use jReality but a self-developed C++ software, but I hope someone can help me, though.
My problem is that I cannot put meshes and point clouds together in one U3D file - and I have no idea what the problem is.
If I add only a mesh - everything is fine. If I add only a point cloud - everything is fine. But if I add a mesh and a point cloud - only the point cloud is rendered when I put the U3D file into a PDF (using Acrobat XI).
I have tried to reverse engineer some U3D examples to pinpoint the error, but without success so far - probably because the examples are not the same as in my use case.
Maybe someone can send me a simple example U3D file (created with jReality) that contains a mesh model (can be a simple cube) and a point cloud model (can be only a dozen of points)? The mesh shall be defined using a Base Mesh Continuation Block, but I think jReality always uses this continuation block type... (The other examples I used to reverse engineer were defined using Progressive Mesh Continuation blocks, but I cannot use these.)
Thanks in advance and kind regards
