writers.gltf
GLTF is a file format specification for 3D graphics data. If a mesh has been generated for a PDAL point view, the GLTF Writer will produce simple output in the GLTF format. PDAL does not currently support many of the attributes that can be found in a GLTF file. This writer creates a binary GLTF.
Example
[
"infile.las",
{
"type": "filters.poisson",
"depth": 12
},
{
"type":"writers.gltf",
"filename":"output.glb",
"red": 0.8,
"metallic": 0.5
}
]
Options
- filename
Name of the GLTF (.glb) file to be written. [Required]
- metallic
The metallic factor of the faces. [Default: 0]
- roughness
The roughness factor of the faces. [Default: 0]
- red
The red component of the color applied to the faces. [Default: 0]
- green
The green component of the color applied to the faces. [Default: 0]
- blue
The blue component of the color applied to the faces. [Default: 0]
- alpha
The alpha component to be applied to the faces. [Default: 1.0]
- double_sided
Whether the faces are colored on both sides, or just the side visible from the initial observation point (positive normal vector). [Default: false]
- where
An expression that limits points passed to a writer. Points that don’t pass the expression skip the stage but are available to subsequent stages in a pipeline. [Default: no filtering]
- where_merge
A strategy for merging points skipped by a ‘where’ option when running in standard mode. If
true
, the skipped points are added to the first point view returned by the skipped filter. Iffalse
, skipped points are placed in their own point view. Ifauto
, skipped points are merged into the returned point view provided that only one point view is returned and it has the same point count as it did when the writer was run. [Default:auto
