Class BufferWriter

java.lang.Object

dev.engine.core.gpu.BufferWriter

public final class BufferWriter
extends Object

Writes typed values to a NativeMemory for GPU buffer upload. Works with any buffer: UBOs, SSBOs, mapped streaming buffers, staging buffers.

Matrices are written in column-major order (GPU convention). Booleans are written as 4-byte ints (GLSL bool layout). Texture handles are written as uint64 (bindless).
