Properties: aspose.threed.shading (aspose-3d-foss)

Aspose.3D FOSS nodrošina divas materiālu klases klasiskajā ēnojuma hierarhijā:

  • LambertMaterial: difūzs matēts ēnojums (bez spekulāritātes)
  • PhongMaterial: paplašina Lambertu ar spekulāriem izcelumiem un spīdīgumu

Abi tiek piešķirti Node caur node.material. Krāsas tiek iestatītas, izmantojot Vector3(r, g, b) kur komponenti ir [0.0, 1.0].

LambertMaterial 

class LambertMaterial(Material):

Properties

A3DObject → Material → LambertMaterial

Properties 

LambertMaterial(name: str = None)

Properties

NameTypeAccessDescription
namestrRead/WriteGets or sets the name.
propertiesPropertyCollectionReadGets the properties.

PhongMaterial 

class PhongMaterial(LambertMaterial):

Properties

A3DObject → Material → LambertMaterial → PhongMaterial

Manto visus LambertMaterial īpašības un pievieno:

Šīs klases manto pamata īpašības no LoadOptions / SaveOptions attiecīgi. Papildu formāta specifiskas īpašības pašreizējai FOSS versijai nav dokumentētas.

SignatureDescription
__init__(name: str)
get_texture(slot_name: str)Not implemented in the FOSS edition — throws at runtime. Retrieves the texture assigned to the specified slot name
set_texture(slot_name: str, texture)Not implemented in the FOSS edition — throws at runtime. Sets the texture value.
find_property(property_name: str)
get_property(property: str)
set_property(property: str, value)Sets the property value.
