Thank you very much Paulo !
It works but only if I keep the source_model attribute...

Python and Java API / Problem with buildTexture

« on: January 03, 2025, 02:25:21 PM »

Hello

I try to build a tiled model from a colored point cloud. I use this process :
   - import point cloud
   - build mesh
   - build texture from mesh
   - build tiled model from mesh with transfer model texture

The process works when I use the app but crashes when I use the python module (even in the app).

Here is my script :

Code: [Select]

chunk.importPointCloud(
    path="point_cloud.ply",
    format=Metashape.PointCloudFormatPLY,
    crs=Metashape.CoordinateSystem("EPSG:4978"),
    shift=Metashape.Vector(shift)
)

chunk.importShapes(
    path="outline.geojson",
    replace=False,
    boundary_type=Metashape.Shape.OuterBoundary,
    format=Metashape.ShapesFormatGeoJSON,
)

chunk.buildModel(
    source_data=Metashape.PointCloudData,
    vertex_colors=True,
    vertex_confidence=False,
    clip_to_boundary=True,
    build_texture=True
)

chunk.buildTexture(
   source_model=0,
   transfer_texture=False
)

...

It crashes on the buildTexture instruction.

I noticed than the parameters are different when I launch the buildTexture from the app :

Code: [Select]

BuildTexture: mapping_mode = GenericMapping, page_count = 1, texture_size = 8192, pixel_size = 0.20326334238052399, texture_size = 8192, fill_holes = off, texture_type = Diffuse map, source_model = 0, transfer_texture = off, anti_aliasing = 1These parameters are a blend of buildUV and buildTexture api instructions.

How can I manage to build the texture to build the tiled model only with python module ?

Thank you

Python and Java API / Pixel size in tiled model

« on: December 09, 2024, 10:29:00 AM »

Hello

I build a tiled model with pixel_size=0, so a default_value is set. Is there a way to recover this default value to use it in another tiled model building. The purpose is to merge both tiled models in a consistent unique tiled model.

Thank you
