Material

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

Aspose.3D FOSS for Java iki malzeme sınıfı sağlar:

  • Material: tüm malzeme türleri için soyut temel sınıf. Bir ad ve sayısal ve renk parametreleri için bir özellik koleksiyonu sağlar.
  • PbrMaterial: Metalik, pürüzlülük, albedo ve ışık yayma özelliklerine sahip Fiziksel Tabanlı Render (PBR) malzemesi. glTF 2.0 ve diğer PBR‑destekli formatlar tarafından kullanılır.

Malzemeler bir Node aracılığıyla node.setMaterial(material).

Properties 

public abstract class Material extends A3DObject

Properties

A3DObject -> Material

Material tüm malzeme türleri için soyut temeldir. Ad özelliğini ve bir Properties kullanıcı tanımlı meta veri koleksiyonunu sağlar. Siz doğrudan örneklemezsiniz Material doğrudan; kullanın PbrMaterial yerine.

PbrMaterial 

public class PbrMaterial extends Material

Properties

A3DObject -> Material -> PbrMaterial

PBR (Fiziksel Tabanlı Render) malzeme. glTF 2.0 ve diğer PBR‑uyumlu formatlar tarafından kullanılır. Atanır: Node aracılığıyla node.setMaterial(material).

Properties 

PbrMaterial()
PbrMaterial(String name)
PbrMaterial(String name, Vector4 albedo)

Properties

NameTypeAccessDescription
MAP_SPECULARStringReadUsed in setTexture(java.lang.String, com.aspose.threed.TextureBase) to assign a specular texture mapping.
MAP_DIFFUSEStringReadUsed in setTexture(java.lang.String, com.aspose.threed.TextureBase) to assign a diffuse texture mapping.
MAP_EMISSIVEStringReadUsed in setTexture(java.lang.String, com.aspose.threed.TextureBase) to assign a emissive texture mapping.
MAP_AMBIENTStringReadUsed in setTexture(java.lang.String, com.aspose.threed.TextureBase) to assign a ambient texture mapping.
MAP_NORMALStringReadUsed in setTexture(java.lang.String, com.aspose.threed.TextureBase) to assign a normal texture mapping.
nameStringReadGets the name.
propertiesPropertyCollectionReadGets the properties.
SignatureDescription
getTexture(slotName: String) → TextureBaseGets the texture from the specified slot, it can be material’s property name or shader’s parameter name.
setTexture(slotName: String, texture: TextureBase)Sets the texture to specified slot.
toString() → StringFormats object to string.
iterator() → Iterator<TextureSlot>Gets the enumerator to enumerate internal texture slots.
A3DObject()Parameterized Cylinder. It can also be used to represent a cone when one of radiusTop/radiusBottom is zero.
getName() → StringThe segments of the curve.
setName(name: String)Constructs a CircleShape profile with specified radius.
getProperties() → PropertyCollectionInitializes a new instance of Cylinder class.
findProperty(name: String) → PropertyInitializes a new instance of the Bone class.
getProperty(name: String) → ObjectGets the transform matrix of the node in current pose.
setProperty(name: String, value: Object)Gets the width segments.
removeProperty(name: String) → booleanGets flip coordinate system of control points/normal during importing/exporting.
