- PURPOSE:
- --------
-
- To match the physical dimensions of advertising posters, it is common for
- a Desktop Publishing image to exceed 10,000x10,000 pixels (RGBA).
-
- IMPACT's Memory-To-Graphics high download rate enables the hardware
- acceleration of a variety of applications , which all need to tile their data.
-
- Similar to the Volume Rendering and Terrain Following techniques, the image
- is drawn - and processed - on a per-tile basis. The new tiles are loaded from
- memory as needed, and then used as textures for Rotation, interpolated Zoom,
- and real-time Convolution.
-
- This demonstration prototype was developped for BARCO, in Belgium.

-
- MANIPULATION:
-
- ---------------------------- Main Window -------------------------------
-
- MIDDLEMOUSE : k: Convolution Filter Kernel
- Convolution Parameters r: reset
- LEFTMOUSE :
- Translation ARROW keys
- RIGHTMOUSE : automatic translation
- Rotation stop with MOUSEBUTTON
- MIDDLE&LEFTMOUSE :
- Zoom
-
-
- -------------------------------- NOTA -----------------------------------
-
- For b&w images, 60HZ roaming can be achieved by pre-interleaving the
- tiles and loading them as pseudo-RGBA textures (see TX_SELECT extension).
- This technique is demonstrated by Bob Shakib's DEMO.shakib example.
