Member Function Documentation
◆ AppendAttribute()
|
pure virtual |
Adds an attribute to a primitive. Multiple attributes can be appended to a primitive.
- Returns
- Status of AppendAttribute.
- Parameters
-
[in] attribute Attribute object.
◆ Create()
|
static |
Creates a primitive.
- Returns
- Primitive object. Do not delete this pointer.
- Parameters
-
[in] gltf GLTF object. [in] type Primitive::PrimitiveType defining type of primitive to create. [in] material Material used to render primitive. [in] indices Optional, indices used to render type. indices are index into appended attributes. If no indices are specified, vertices are grouped as appropriate for primitive type. [in] isPickable Optional, primitive can participate in probing, hit-detection, and pivot point selection. A 2D overlay is an example of something this is not pickable.
- Examples
- Test002.cpp, Test005.cpp, Test008.cpp, Test009.cpp, Test010.cpp, Test013.cpp, and Test014.cpp.
◆ Create2DTexture() [1/2]
|
static |
Creates a 2D billboard from a texture.
- Returns
- Primitive object. Do not delete this pointer.
- Parameters
-
[in] gltf GLTF object. [in] texture Texture object used to texture billboard. [in] width Width of billboard. Ranges from 0 to 1 as fraction of minimum screen dimension. [in] height Height of billboard. Ranges from 0 to 1 as fraction of minimum screen dimension. [in] x X screen location. Ranges from 0 to 1. [in] y Y screen location. Ranges from 0 to 1.
◆ Create2DTexture() [2/2]
|
static |
Creates a 2D billboard from a texture.
- Returns
- Primitive object. Do not delete this pointer.
- Parameters
-
[in] gltf GLTF object. [in] texture Texture object used to texture billboard. [in] width Width of billboard. Ranges from 0 to 1 as fraction of minimum screen dimension. [in] height Height of billboard. Ranges from 0 to 1 as fraction of minimum screen dimension. [in] xAttach X location attachment. [in] yAttach Y location attachment.
- Examples
- Test005.cpp.
