Important Question befire purchase...

[wamir]

Hi guys, i' m new in the forum and TV3D... this morning i was buying the TV3d 6.2 for a my project. I read on the forum that after can download the 6.5 beta version. But i would know if i can do a particolar function. I must load a huge terrain (circa 130000x150000 pixels) using an heightmap of 1024x1024 bmp graysale (and i read that the 6.5 can do a LOD terrain, ok). On this terrain on first step (where camera stay much far)  i must load a big texture that cover all terrain, but when i go near in step, it must load in the zone of the "point of view" a detailed texture that cover a specifiched zone at specifc coordinate), then if i go more near must load another detail texture apply on the previous texture (logically on an area smaller than the previous texture), and so ahead.

Is this method supported in the 6.5, or similar technique can be applied?

I try to do this in pure code of VB6 using directx 8.1, using a my personal primitiv algorithm for lod (a little bit slow) and dynamic texture for apply the detail texture step by step with zooming camera, but the max of detail texture that i did can crate was 1024x1024, and this not is good, because I must to obtain at max zoom a resolution of 1 pixel of texture = 1 pixel of terrain!

I' m sorry for long question, and for my english.. i' m italian!
THANKS VERY LOT FOR ANSWERS.
Good Day to everyone.

PS.: can i buy online the 6.2 and endured after download the 6.5?

Yep you can do that with TV3D.  You can place textures across the whole landscape for low resolution, and when you zoom in closer you can replace the textures per chunk with higher resolution very easily.
