nw::gfx::res::ResFileHeader::GetFirstBlockHeader Member Function

const nw::ut::BinaryBlockHeader & GetFirstBlockHeader() const;

None.

Returns a reference to binary block data.

Gets binary block information.

There are two kinds of blocks that can be specified inResGraphicsFile: DATA, indicating a regular data block, and IMAG, indciating a texture or vertex image block. You can get an image blocks using the nw::ut::GetNextBinaryBlockHeader function, and keep the cost of transferring image data to VRAM down by transferring them all at once to VRAM. In this case, gather the image data on the application side, and calculate the VRAM address for each based on the transferred VRAM address and address information for image data in each resource, and then set addresses before Setup using the SetLocationAddress functions located in the ResImageTexture, ResVertexStream, and ResIndexStream classes.
