NodeTextureBuffer()

MayaFlux::Buffers::NodeTextureBuffer::NodeTextureBuffer ( std::shared_ptr< Nodes::GpuSync::TextureNode >  node, std::string  binding_name = "texture"  )

explicit

Create texture staging buffer from generative node.

Parameters

node	TextureNode that generates pixels each frame
binding_name	Logical name for this texture binding (default: "texture")

Buffer size is automatically calculated from texture dimensions: width * height * 4 channels * sizeof(float) = RGBA32F format
