Object viewer based on Vray PPT

[Micha]

Hello,

I'm looking for a solution to show 3D object to clients per a little viewer. I looked around at the web, but don't found a solution.

The features should be:
* showing 3D with textures
* not based on baking light textures
* support reflections per graphic card

Why did I post it here? As I have seen the 3D view of the IMviewer and I got the idea, could it be possible, that the IM is filtered and multiplied to a 3D object with textures, so that a cheap standard graphic card could show the 3D model with GI lighting?

An other question is ask me, could this technic combined with PPT? My idea is, that I open a 3D model, let PPT run, but all calculated samples are saved. If I turn the model, new samples are added, but the old one are not cleared. So, my dream, the model get the lighting information at all surface points. This light solution could be used to show the model.

Why I try to avoid baking of maps? Baking is not easy to implement at every 3D application, for example Rhino3D. Also, the calculation of the maps of a complex models isn't fast and the texture coordiantes must be set right.
In the past I have seen a Vray RT example and I was impressed, how fast the lighting was calculated, but the calculation was cleared after every little movement of the camera.

My wish is, that I could open a 3D model in a "creator modul". There I set the materials and the environment. Than the light solution is calculated. From light solution + 3D Model + textures + material informations can be saved a 3D modell, that can be shown per free "viewer modul".

Maybe it's usefull to show 3D models without mesh objects. Only color information, 3D coordinates and surface normal are used, like the IMviewer show the model - 3D space color Pixels. I'm not sure it's a good idea, maybe to much memory is needed.

My english isn't the best, but I hope, the idea is described good enough.

This tool could be an easy method for designers to show concepts. My clients ask me often, to create turntable views of objects. At the moment I create Object movies based on a few hundred images, that need much time for calculation.
I hope, there is a way, to combine the great PPT/RT technic with a viewer based on precalculated light solutions.

Hmm, sounds interesting...

When I read the title, first I thought that it's pretty much what you will get with the VRay realtime preview. But interpolating back cached irradiance on a 3d model running on the gpu is something pretty different. But not a bad idea at all imo. Still, you would need to code bumps, reflections, etc.

I think, for showing models on a turntable, the RT would be sufficient, based on the speed demos seen so far, and the fact that cpu's are getting faster and cheaper every minute. The update is continuous, so the client won't get the feeling of waiting for something to happen. Instead, it's progressive, and fun to watch.

What I would really like to see, is an accessible RT engine, where I can initialize an RT window in any custom application, and write some stuff based on the remarkable speed of this technology. For example, I've got a material editor in mind, where you've got a simple floater with an interchangeable material preview scene inside an RT window, material properties below it, simple tools to grab and put from and into the scene. Right now, this is a pretty easy task in maxscript, all it lacks is a good preview solution. And guess what an RT canvas would be spectacular for?

Best regards,
