ildraw(3G) ildraw(3G) NAME ildraw - selects a previously allocted ilbuffer as the drawing destination C SPECIFICATION void ildraw(long buffer) PARAMETERS buffer expects a value from 1 to the number of buffers returned by ilbuffer(buffers); DESCRIPTION ildraw selects one of the buffers previously allocated by ilbuffer as the destination for drawing. Passing a value of 0 deselects the buffer. The ilbuffers are screen-sized, and the coordinate system reflects this. Viewport should be called after this routine to set the area of the screen sized buffer that is being used. Beware of programming errors in coordinate systems when copying to or from a windows front and back buffers and the ilbuffer. SEE ALSO ilbuffer NOTES This subroutine is available only in immediate mode and on RealityEngine systems running 5.0.1 or later. Page 1[top]
