Code archives/3D Graphics - Effects/Glow Effect

Hi,

its very well! Exactly what I need!

thx

Great !

Excellent,

I will used this idea for my FPS Engine !

This will be very useful for a strategy game with glowing objects, where they are all really small and in large numbers... Thus needing a fast routine that looks good from afar.

It seems to work just as well, removing the first RenderWorld statement, which ought to give faster results in a complex scene.

Try this slightly adjusted version...

MoveEntity sp,-.25,-0.06,1.21
ScaleTexture glowtexture,GraphicsWidth()/sizex,GraphicsHeight()/sizey
EntityTexture sp,glowtexture

TextureBlend glowtexture, 5    ;Also try mode 2 ...and increase the Alpha from 0.44 to about 0.80
EntityAlpha sp, 0.44

While Not KeyDown( 1 )
	TurnEntity cube,0.5,0.5,0.5
	CameraViewport camera,0,0,sizex,sizey
;	RenderWorld
	CopyRect 0,0,sizex,sizey,0,0,BackBuffer(),TextureBuffer(glowtexture)
	CameraViewport camera,0,0,GraphicsWidth(),GraphicsHeight()
	
	RenderWorld
	Flip
Wend

End

WOOOOOOOOOOOOOOOOOOWWWWW!!!!!!!!!!!!!

Wow. Very nice.

This can be optimised further and can also be made more dynamic with regard to resizing.

I'll expect an amened version within the week.

Thank you.

Nice!

So nice! Will definitely use this sometime!
