loadFromMemory

Loads a GaussianSplattingResource directly from in-memory data.

Use this when the resource bytes are already held in a direct ByteBuffer (for example, mapped from a file you opened yourself, downloaded over the network, or unpacked from a custom asset container) and you want to avoid copying them into a temporary file or byte[] first.

WARNING:

• This method is blocking. While it can be called on the main thread, large resources may cause jank or even ANR.

• Prefer invoking from a background thread or coroutine, e.g. withContext(Dispatchers.IO) { GaussianSplattingResource.loadFromMemory(buf, "spz") }.

Usage

val buffer: ByteBuffer = ByteBuffer.allocateDirect(bytes.size).apply {
    put(bytes)
    flip()
}
val resource = withContext(Dispatchers.IO) {
    GaussianSplattingResource.loadFromMemory(buffer, "spz")
}

Buffer Requirements

• data must be a direct ByteBuffer (e.g. obtained via ByteBuffer.allocateDirect(...) or by memory-mapping a file).

• The bytes between the buffer's current position and limit are treated as the resource content (i.e. data.remaining() bytes starting at data.position()). The buffer's position/limit/mark are not modified by this call.

• The buffer must remain valid (not unmapped/freed) until this method returns.
