My first "scene" test using my sprite based foliage within a simple setup :) . I will get started on a simple scene that will have hanging vines in them, later ;)

Hello,

The tree does not look very beautiful.
Why don't you use a real polygonal foliage tree if you have got just one?

I like the effect. Has a fantasy look to it.

Well it was not titled "beautiful tree",( like i said, "testing sprite based foliage" ) to answer one question;) and why have un-needed polygons when you do not need to bother with geometry, and long render times...and theres only one because its a test scene...and about "just not using polygons", i simply could, but its always better know more than one solution for something;) Bye


thanks Chewey

thanks rendermonkey, i guess you also live in a world were all trees are not "beautiful trees":p ;)

hey man that tree is not beatiful, :D

Good idea going the sprite way , is it just one sprite image or multiple images?

i didnt get the blur though , it looks like its blurred randomly. was it a problem caused by the sprites or intentional?

nice job

Thanks sheepfactory,
it is one sprite surface with 2 inset layers. yeah, since the image was only a "tester" i did a really quick post procession job, thats why the blur looks a little funny, its not the sprites... this scene is just a quickTest , thrown together really quickly just to see how my sprite foliage "generally" looks when its applied differently

Thank you for the explanation Amassador. However, I still do not like the effect but it is very "creative" like and interesting for some purpose.

I think it's brilliant, great use of the tools and it has a unique look that will make viewers used to the trite overused 3D tree. A very interesting technique and it looks great!

the disadvantage of using sprite based foilage is that they dont't throw shadows...

afaik

David Lightbown , thanks:)

bytehawk,
actually they DO "cast shadows" ;) as a "solid", just not "self shadowing", but thats easily simulated ;)...but of coarse this method would not generally be used for "close up shots"

Hi,

You're right, it does work.

here's some tests with volumetric and sprite based particles and shadow mapped/raytraced shadows

tha flowers are sprites too

Whatever happened to these images?
Whatever happened with these tests??

Probably something to do with the magic of "archiving"

Not quite as malevolent as "newspeak" though. A bit like your datoids floating off the edge of the flat web universe and into a black hole.

Hey, wgreenlee1,
The pics don't show up for you, either???

Tried it on all my browsers and I get no pics.

oh well...


[Edit: Thanks Chewey! I've been wondering what the hell has been wrong with my system.]

WTF:applause: hehe Cman, dude this thread is more than a year old:wip: , im suprised its still here at all


how did you end up back here:scream: If you would like I could re-post the images for you. About the tests, I did not do much more experimentation with them after this, I think I moved onto doing single voxel experimentation right after this...I forget, but I did use it recently to make an abstract forest image, I belive I posted it here about a month ago.

Images probably got cut. :shrug:

Hey nice work and I love the cartoony style of your character. nice detail in the model as well, should be great for animation.
