		Real3D v2.0 OpalVision Driver.


			  INSTALLATION

Copy the file 'Opal_r3d.library' included in this archive to
your libs: directory.


			USING THE DRIVER

This driver allows access to the OpalVision display via the
'External Screen' controls in Real3D's Project menu. To activate
the driver:

1) Select 'Project/External Screen/Settings'.
   Type in 'Opal_r3d.library' in the library box.
   (NOTE: This setting can be saved along with the
    current environment).

2) Select 'Project/External Screen/Open'.
   (You will only need to do this once per session).

3) Select 'View/Render/Settings' (or Amiga-s).
   Click on the 'Output' cycle gadget (top-left) until
   the text 'External' appears.
   (NOTE: at this point the Width and Height fields will
    be changed to the OpalVision display size. If you
    change the Opal display resolutions, you may need
    to repeat this again to refresh the Width and Height
    fields).

4) To render the image in 24bit, select 'View/Render/Window'
   (or amiga-r).

   Once the render has completed, the image will remain 
   displayed until the left mouse button is pressed.

   To abort the render, hit the 'Esc' key. The display will
   also remain displayed until the left mouse button is 
   pressed.


5) After the image has been rendered, it can then be saved
   using 'Project/External Screen/Save' this will save the
   image either using Real3D's file formats or the OpalVision
   formats (see below).

6) If you wish to reclaim some memory, select
   'Project/External Screen/Close' This will remove the last
   24bit image from memory. (NOTE: if you wish to use the
   OpalVision display again you'll have to repeat step 2).

7) Selecting 'Project/External Screen/Set Modes' will bring
   up a requester which will allow the 24bit display resolution
   to be selected. It also allows the OpalVision file format,
   that can be used for saving 24bit images, to be selected.
   The file formats will include the 3 standard Opal file
   formats (IFF, Fast and JPEG) as well as any OpalVision LSI
   (loader Saver Interface) modules installed into your system.

   To save 24bit images using Real3D's file formats, select
   'Project/External Screen/Settings'. From this menu you
   can select the file formats to be used, if 'Custom' is
   selected, then the OpalVision file format as selected
   in the 'Set Modes' menu will be used.

8) To force make the 'Set Modes' menu appear on the current
   screen, select 'Project/Window/Screen'. Tick the 'Public'
   box and select the 'Default' gadget. The same text should
   appear in the 'Current' and 'Default' fields.
