- RENDERING A REFLECTION OF AN OBJECT THAT HAS BOTH A COLOUR- AND
- TRANSPARENCY- MAPPED ONTO IT SO THE REFLECTED OBJECT APPEARS TO HAVE THE
- SHAPE OF THE BRUSH MAP USING IMAGINE 2.0
- ==========================================================================
-
- How's that for a title??
-
- OK.. the files you are getting in this article:
-
- Tree.iob - a plane with the two brushmaps on it. Note the plane's colour
- is actually BLUE (RGB=0|0|255)
- Mirror.iob - basically a plane with a chrome attribute
- Tree.colour - the colour brush map
- Tree.trans - the transparency brush map
-
- Detail.pic - a snapshot of the detail editor showing how the scene was set
- up. Note I added the ST phaser in later to emphasize the
- effect of the shot, and it's not represented here.
-
- Render.pic - the rendered image - trace mode.
-
-
- Notes on implementation:
-
- · Set the "Max Level" on the transparency brush map to 240, not 255. As
- per "Understanding Imagine 2.0" (page 40)
-
- · Set the "Dithering" of the object to 255. A value of 0 results in a
- slight darkening behind the "transparent" object
-
- · Note that overlapping the mirror with the transparent object renders that
- area black in Trace mode. It will render normal colour in Scanline
-
- That's it for this tutorial. TTYL.
