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.

This subroutine is available only in immediate mode and on RealityEngine
