Texture splatting without shaders ?

vincent-v · Post by **vincent-v** » Mon Jan 25, 2010 8:24 pm

Is there a way to acheive texture splatting without usage of shaders ? I found some informations about Sprintz' irrlicht which would implement this but there is no link to download it.

For those who already used 3D World Studio : did you understand how texture splatting is working in this software ? I didn't see any alphamap...

Thx for answers

i used 3d world studio for a short time, and there is an alpha map. just you make it in realtime (you can even export it XD)

Is it really that hard to use one which uses Shaders?

Shaders are by the way, waaaaaay faster than Fixed function/CPU rendering.

Half of my systems do not support shaders, at least not high-level ones. And many mobile systems don't have any. Depends on your target systems probably, but it's not just that simple.

Yeah seriously. 9999 Posts!!!! That's shrieking huge.

On the other hand I did see shaderless texture splatting somewere. I have no clue were though. If u change ur mind though I have lots of code for shader crazy texture splatting.

Yeah, I really thought what I should post as my 10000th one, but I simply forgot to make it any special now

Indeed you're right. But I'm confused because I still don't have the alphamap in the folder where I have exported my map to DBO format. Would it be embedded in the file ?

My graphics won't be very good so I think it is the opportunity to make my apps running on a wide range of systems. Moreover as Hybrid said it would be nice to have that texture splatting on mobile systems.

I'm interested by your proposal ^^ It will be useful if I cannot solve my problem.

Happy 10000th post

The next opportunity to make a special post is very far away now ^^

yea probably it is in the dbo.

and here is that splatting what ace was talking about

i haven't use it, so i dont know if it works

Thank you, I'm going to try this
