shadow system : GOM

Hauvent & Philippe C.

You find enclosed a link to a free source code for a shadow system library for less than 20 3Dobjects in the same time and small terrain.

This library is done in blitZ3d.

It is not perfect , but it is a good starting point. If you want improve it , do it.

For more information download the demos and source code : http://perso.wanadoo.fr/philippe.c/#GOM

This project is based on the code developped by this 2 people :

- jfk EO-11110 http://www.blitzbasic.com/codearcs/codearcs.php?code=434

- Mikkel Fredborg http://www.blitzbasic.com/codearcs/codearcs.php?code=1010

Without the code published by this 2 people this library will never exist.

Thanks to them.

To do this libray we have mixed the 2 approachs :

JFK => create a quad to project the shadow.
Fredbord => compute the texture uv in order to display the shadow texture.

The documentation is provided in the zip file with the source code

looks really nice Phillipe... thx...

Looks good .... I noticed that sometimes the shadows disappeared and jump to their new location a few frames later. Not sure if this was meant as an optimisation?

Stevie

good job!

Can I use this for static object?

Looks a little bit like sswifts system but not quite.

Boiled Sweets : yes you can use for static object => see demos

@Stevie G
i noticed this too it happens maily on demo04 and demo99. Also the shadows look out of place sometimes. Apart from that good job.
