MorphTargetBuffer

A container for vertex morphing data that supports both automatic and manual morphing.

MorphTargetBuffer operates in a hybrid model depending on the attribute being morphed:

1. Automatic for Built-ins (positions/tangents): Enable via withPositions(true) or withTangents(true). The MorphTargetBuffer will allocate internal storage and hold the data for these attributes, which you upload via setPositionsAt() or setTangentsAt(). The framework automatically applies the morphing logic in the vertex shader.

2. Manual for Custom Data (e.g., UVs, colors): The MorphTargetBuffer does NOT hold data for custom targets. The user is responsible for the full data pipeline:

• Create and manage a separate Texture to hold the morph target data (offsets).

• In the material, declare a sampler2d_array parameter.

• Bind the Texture to the material instance.

• In the vertex shader, manually call morphData2, morphData3, or morphData4 with the custom sampler to apply the morphing.

A MorphTargetBuffer object must be associated with a Renderable via RenderableManager.Builder.morphing() to enable the morphing pipeline.
