scene with 100 millions polys

Post by manowar »

Hello
I am working on a data visualisation projet and would like some advice on using Ogre for this project. My main question is about the huge data size (it should be a 5000*10000 points set of data which is around 100 millions of triangles). The far clip plane will be relatively near though. I was thing of splitting the huge terrain into smaller (100*100 vertices) patches (entities) and let Ogre doing the frustum clipping.
It means that I will have around 5000 patches or entities (100x100 grid). Rendering is quite simple (color according to the height of the point). I must be able to pick vertices and retrieve data related to the pick vertex from memory. Do you thing it will work ? Any advice ?
Thanks a lot

You should look at the Paging Landscape Scene Manager in ogreaddons for a terrain as large as this.
