Constructor & Destructor Documentation

MayaGpuAll()

MayaGpuAll::MayaGpuAll

(

const MayaGeometryAll &

mia

)

Create a set of instances on the GPU from a set of instances.

Parameters

mia	Set of instances.

References MayaGeometryAll::instances, and instances.

Member Function Documentation

Append() [1/2]

void MayaGpuAll::Append

(

const MayaGeometryAll &

scene

)

Append a set of instances with the existing one.

Parameters

scene

The set of instances.

References Append(), and MayaGeometryAll::instances.

Append() [2/2]

void MayaGpuAll::Append

(

const MayaGeometrySet &

ins

)

Add an instance set to the scene.

Checks if the object already exists in the collection of models: if so, it simply creates a new reference to it, otherwise it creates a new entry.

Parameters

ins	The instance.
