Method Detail

boneCount

@NonNull
public SkinningBuffer.Builder boneCount(@IntRange(from=1L)
                                        int boneCount)

Size of the skinning buffer in bones.

Due to limitation in the GLSL, the SkinningBuffer must always by a multiple of 256, this adjustment is done automatically, but can cause some memory overhead. This memory overhead can be mitigated by using the same SkinningBuffer to store the bone information for multiple RenderPrimitives.

Parameters:

boneCount - Number of bones the skinning buffer can hold.

Returns:

this Builder object for chaining calls

initialize

@NonNull
public SkinningBuffer.Builder initialize(boolean initialize)

The new buffer is created with identity bones

Parameters:

initialize - true to initializing the buffer, false to not.

Returns:

A reference to this Builder for chaining calls.

build

@NonNull
public SkinningBuffer build(@NonNull
                            Engine engine)

Creates and returns the SkinningBuffer object.

Parameters:

engine - reference to the Engine to associate this SkinningBuffer with.

Returns:

the newly created SkinningBuffer object

Throws:

java.lang.IllegalStateException - if the SkinningBuffer could not be created
