Hi guys,

Is LOD in Advanced Terrain available yet? It was said in Newsletter #17 that there is going to be an addition to Advanced Terrain called PLUS will introduce LOD and other advanced things..

I need LOD for my project and I'm waiting for second year now..

Thank you,
mhack

You could code it your self by switching the texture that is used on the matrix. Having said that i havn't really used terrains much but it should be similar to LoD on 3d objects.


Thats how i would do it anyway

You certainly wont see anything like that until FPSC is complete and probably for a while afterwards...

I've no idea actually... It could, but you would need a fair few textures.

Yes, textures do take up a lot of textures...

LOD with textures?

LOD - is level of detail, meaning automatic reduction of number of polygons depending on the camera location etc.

Do 3D objects have LOD now?

Ok, if LOD is not available (surprise, surprise ) is there a help file for new vertex manipulation commands in 5.8 patch?

There are 2 types of LOD systems. One adjusts the polygon level of detail and one adjusts the complexity (size/memory) of the texture. The polygon level is what you want and I don't think there is any guess as to when advenced terrain plus will be out.

The problem is texture object is slow with any seriously sized texture. I wonder if there's a performance hit when you take stuff out of the rendering pipeline (using exclude object on?) ... You could in theory have 3 versions of the object, all ready, in position and switch between them using exclude object on/off. Then again, if I remember correctly, we're waiting for the next patch in order to correct some odd behaviour on the exclude commands...

New 'n' Improved sig details how little I accomplish
