Transfer Vertex-Attributes to Texture bad texture results #1269

Open cRuntX opened 2 years ago

cRuntX commented 2 years ago

Hello,

I use MeshLAB 2022.02 ( Windows 64 16GB RAM Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz 4.00 GHz)

First of all I just want to say how much I love your software and to thank you for all the hard work you have put into it!!! :)))

So currently I am working on creating a textured mesh from point cloud data. Firstly, I Compute the Normals for point sets; then Screened Poisson to create a mesh; then Parametrisation: Trivial Per-Triangle and lastly Transfer Vertex-Attributes to Texture.

It all seems to work flawlessly but my texture result is very bad, it doesn't appear smooth but rather triangulated. (Have attached screenshots below)

I have tried many different values for the px Dimensions but the result always seems the same.

I would really appreciate it if you can help me! Thank you!!!

It is challenging, you can refer to https://github.com/cnr-isti-vclab/meshlab/issues/1211.

I'm pretty sure your issue is Parametrisation: Trivial Per-Triangle, you'll want to use a real UV Unwrapper, like Blender's "Smart Project" or xatlas.
