Intel Embree real-time ray tracer
show user profile  advance-software
As promised, here's a 64 bit build :

http://advance-software.com/misc/embree_x64.zip




Intel project homepage: http://software.intel.com/en-us/videos/photo-realistic-rendering-at-researchintel-days-2011
Intel forum here : http://software.intel.com/en-us/forums/embree/
Link to our initial discussion in the spam thread : http://maxforums.org/threads/spam_alert/0138.aspx

Instructions
=======

To interactively display a scene, enter the following command:

embree -c scene_filename.ecs

A window will open and you can control the camera using the mouse and
keyboard. Pressing c in interactive mode outputs the current camera
parameters, pressing r enables or disables the progressive refinement
mode.

The navigation in the interactive display mode follows the camera
orbit model, where the camera revolves around the current center of
interest. The camera navigation assumes the y-axis to point
upwards. If your scene is modeled using the z-axis as up axis we
recommend rotating the scene.

LMB: Rotate around center of interest
MMB: Pan
RMB: Dolly (move camera closer or away from center of interest)
Strg+LMB: Pick center of interest
Strg+Shift+LMB: Pick focal distance
Alt+LMB: Roll camera around view direction
L: Decrease lens radius by one world space unit
Shift+L: Increase lens radius by one world space unit



To compile 64 bit version from source
=======================

1. install - this specific order is required when using vc express.

install windows 7 x64
install vc express 2010
install mssdk 7.1 amd64 including compilers
install vc 2010 sp1 (uninstalls x64 compiler !)
install vc-Compiler-kb2519277.exe to fixup compiler again.

Ref :http://blogs.msdn.com/b/windowssdk/archive/2011/03/08/windows-sdk-v7-1-with-visual-studio-2010-service-pack-1-potential-issue-with-x64-ia64-visual-c-compilers.aspx
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=4422

2. load project in vc2010 express, then switch runtime from v100 to Windows7.1 SDK in configuration properties->general->platform toolset for each 64 bit project in the solution.

3. build

Thanks for doing all this for us, Steve. I had a fun day experimenting with this. It can produce amazingly quick renders. It's not been that easy trying to figure how to get stuff into it the way I want to.

For anybody wanting to get their Max models into this, here's how.

1) Load your model in Max.

2) Apply standard materials to the parts. The specular controls affect the reflectivity of the rendered object.

3) Export as .OBJ, use the default settings.

4) Reference the .OBJ in a .ECS file (refer to the samples that are available on the Intel site)

5) Use the command (or better, create a .bat file) "embree -c filename.ecs"

This limits what you can do with the materials though. Better materials can be coded in .XML files. I believe I can reference objects in the .OBJ file to give them better mats, but I haven't had time to try yet. I think a maxscript exporter that works well might be possible.

Some earlier farting about with it.


Funding, AS? This is open-source. I thought you supported open source? ;)

that's about 2 min. pretty damn impressive. using about double the memory now, almost a gig.

Can anybody figure out what the heck the .bin file is? It contains all the object data for the crown object. If I could figure that out, I might be able to export in a similar way.

haven't looked but it's probably the vertex/connectivity info. no idea what format. email intel or ask on their forum.

The Intel forum doesn't seem to be that active, sadly.

The .bin file is not one I can read, as it's gibberish. Looking at the XML that references it, it must contain named lists of objects (vertex, face, etc).

I hope I can figure out how to export properly to it.

Oh, and for those interested, Max units match those that Embree seems to use. Mirrored in an odd way though, and not just the normal Y/Z fiasco.

Ha ha, I posted there today, and sent an email. I guess I'm a bit impatient.

I must get a better home computer. Mine doesn't have SSE3, so I can't use this. Boo hoo!
