Problem texture
« on: December 06, 2017, 11:14:42 AM »
Hello everyone,

I'm having a problem with texturing a 3D mesh.
I realized an acquisition with a static Lidar + 360 ° views.
I loaded the Lidar dot cloud in .ply that I meshed.
The photographic stations are georeferenced and position themselves well in relation to the Lidar point cloud.
When I calculate the texture from the 360 ° images I get a white template (in Photoscan 1.4), see attachment.

Do you have an idea for the problem?
Thank you very much.

Hello gaetan73,

Can you please also post the screenshot of the mesh in Solid view and the texture parametrization from View Mesh UVs dialog?

Hello gaetan73,

Looks like the normals are inverted. Can you try to use Invert Normals option in the Tools menu -> Dense cloud section and then rebuild the mesh and texture?

Hello gaetan73,

I thought that you are using version 1.4.0 pre-release and have imported the dense cloud.

You can do that in the version 1.3.4 for mesh using the following Python code:
Code: [Select]
import PhotoScan
chunk = PhotoScan.app.document.chunk
for face in chunk.model.faces:
    face.vertices = (face.vertices[0], face.vertices[2], face.vertices[1])
Then you may need to switch to another view mode (sparse cloud, for example) and switch back to solid view.
