Description of a surface material attribute.
typedef struct { API_Attr_Head head; Int32 filler_1; API_MaterTypeID mtype; short ambientPc; short diffusePc; short specularPc; short transpPc; short shine; short transpAtt; short emissionAtt; short filler_2; API_RGBColor surfaceRGB; API_RGBColor specularRGB; API_RGBColor emissionRGB; API_AttributeIndex ifill; short fillCol; short filler_3; API_Texture texture; } API_MaterialType;
Members
- head
- Contains the header information, including type and database index.
- mtype
- The type of the material. Usable values are enumerated in API_MaterTypeID.
- ambientPc
- The reflection of ambient light. [0..100]
- diffusePc
- The reflection of diffuse light. [0..100]
- specularPc
- The reflection of specular light. [0..100]
- transpPc
- Transparency factor. [0..100]
- shine
- The shininess factor multiply by 100. [0..10000]
- transpAtt
- The transparency attenuation multiply by 100. [0..400]
- emissionAtt
- The emission attenuation factor multiply by 100. [0..65535]
- surfaceRGB
- The color of the surface.
- specularRGB
- The specular color.
- emissionRGB
- The emission color.
- ifill
- Internal use
- fillCol
- Color number of defined 3D hatch (0 means: use BODY color)
- texture
- The texture of the material.
Remarks
This attribute type is also used by the 3D components. The material of a 3D polygon can be accessed through the API_UmatType structure.
There is no additional data assigned to material attributes in the API_AttributeDef structure.
Pay attention to the texture
member if its fileLoc
pointer is dynamically allocadted.
Requirements
- Version: API 1.3 or later
- Header: APIdefs_Attributes.h
