texture - texture handle frame (optional) - texture frame |
|
Returns the handle of a texture's drawing buffer. This can be used with dxSetBuffer to perform 2D drawing operations to the texture, although it's usually faster to draw to an image, and then copy the image buffer across to the texture buffer using dxCopyRect. You cannot render 3D to a texture buffer; 3D can only be rendered to the back buffer. To display 3D graphics on a texture, use dxCopyRect to copy the contents of the back buffer to a texture buffer. |
