Image Description, by
These screenshots are taken from our project called 'Alnair'. It is a 100%
pure Java 3D-engine and it is not using Sun's Java3D API. We planned to use
it as the graphical heart of a MMORPG game which we are no longer
developing, unfortunately. The basic version of the game was planned to be
playable via a standard browser without any further plugins. Therefore the
design goals were to get as many polygons out of Java as possible and to
reduce the download size of 3D data to a minimum.
The upper two pictures just show some basic features of our engine such as:
z-buffer rendering
texture mapping
gouraud shading
specular mapping
alpha channel
faked texel filtering (ala Unreal)
FSAA
Some technical details about the images:
Upper image
1934 polygons
three textures each 256x256x24
mesh size: 13939 bytes
texture size: 21120 bytes
rendering speed about 35fps at 512x384 pixels on my Athlon 900
Lower image
25676 polygons
mesh size: 135627 bytes
rendering speed about 15fps at 512x384 pixels on my Athlon 900
The textures are standard Jpeg encoded. The models were compressed without
any loss of precision using our own mesh packer. Basically they are stored
as triangle strips. Currently the size of the Java-applet is 13359 bytes.
As this is a commercial project I can not release the source code. But you
can take a look at a working demo at http://www.alnair.de
Cheers,
Thomas
