trimesh.visual.texture
- class trimesh.visual.texture.TextureVisuals(uv=None, material=None, image=None, face_materials=None)
Bases:
trimesh.visual.base.Visuals- __init__(uv=None, material=None, image=None, face_materials=None)
Store a single material and per-vertex UV coordinates for a mesh.
If passed UV coordinates and a single image it will create a SimpleMaterial for the image.
- Parameters
uv ((n, 2) float) – UV coordinates for the mesh
material (Material) – Store images and properties
image (PIL.Image) – Can be passed to automatically create material
- concatenate(others)
Concatenate this TextureVisuals object with others and return the result without modifying this visual.
- Parameters
others ((n,) Visuals) – Other visual objects to concatenate
- Returns
concatenated – Concatenated visual objects
- Return type
- copy()
Return a copy of the current TextureVisuals object.
- Returns
copied – Contains the same information in a new object
- Return type
- crc()
Get a CRC of the stored data.
- Returns
crc – Hash of items in self.vertex_attributes
- Return type
int
- property defined
Check if any data is stored
- Returns
defined – Are UV coordinates and images set?
- Return type
bool
- face_subset(face_index)
Get a copy of
- property kind
Return the type of visual data stored
- Returns
kind – What type of visuals are defined
- Return type
str
- to_color()
Convert textured visuals to a ColorVisuals with vertex color calculated from texture.
- Returns
vis – Contains vertex color from texture
- Return type
trimesh.visuals.ColorVisuals
- update_faces(mask)
Apply a mask to remove or duplicate face properties, not applicable to texture visuals.
- update_vertices(mask)
Apply a mask to remove or duplicate vertex properties.
- Parameters
mask ((len(vertices),) bool or (n,) int) – Mask which can be used like: vertex_attribute[mask]
- property uv
Get the stored UV coordinates.
- Returns
uv – Pixel position per- vertex
- Return type
(n, 2) float
- trimesh.visual.texture.power_resize(image, resample=1, square=False)
Resize a PIL image so every dimension is a power of two.
- Parameters
image (PIL.Image) – Input image
resample (int) – Passed to Image.resize
square (bool) – If True, upsize to a square image
- Returns
resized – Input image resized
- Return type
PIL.Image
- trimesh.visual.texture.unmerge_faces(faces, *args, **kwargs)
Textured meshes can come with faces referencing vertex indices (v) and an array the same shape which references vertex texture indices (vt) and sometimes even normal (vn).
Vertex locations with different values of any of these can’t be considered the “same” vertex, and for our simple data model we need to not combine these vertices.
- Parameters
faces ((n, d) int) – References vertex indices
*args ((n, d) int) – Various references of corresponding values This is usually UV coordinates or normal indexes
maintain_faces (bool) – Do not alter original faces and return no-op masks.
- Returns
new_faces ((m, d) int) – New faces for masked vertices
mask_v ((p,) int) – A mask to apply to vertices
mask_* ((p,) int) – A mask to apply to vt array to get matching UV coordinates Returns as many of these as args were passed
