2.5D Impostor Tree

2.5D Impostor Tree

This demo is made for "Hardware Accelerated Rendering of Foliage for Real-time Applications" SCCG 2003 paper by Gabor Szijarto and Jozsef Koloszar. (Best Paper Award)

Demo shows a detailed tree:

• 19834 polygons branches

• 46 polygons leaf

• 70*512 = 35 840 leaves

• equal to 1 668 474 polygons tree

It's a very beta version, thus maybe it has some bug. Moreover it is not optimized. All shaders are compiled by nVidia's Cg.

Moving in the program:

• "z"-"x" : rotation

• "r"-"f" : view point up - down

• "1"-"2" : fov

• "w"-"s" : forward - backward

• "a"-"d" : left - right

• "`" : save screenshot.

Requirement:

• DirectX 9

• Windows 98/ME/NT/2000/XP

• Pixel shade 2.0 and Vertex shader 2.0 or above for hardware running. (e.g. ATI R3xx and nVidia NV3x )

• It is working with reference driver (you must turn on at DirectX control panel).
