Rendering #1

Closed ghost closed 9 years ago

ghost commented 9 years ago

Dear Quian-Yi, thank you very much for sharing your great work! I am having a question about how to render the voxel representation. In your paper you show beautiful images of the reconstructed scene. How did you do this? Did you apply some "heavy" rendering like Maya or was it pure in opengl?

Thank you very much!

Regards Eugen

Yeah, same question here. But this question shouldnt be openned as an 'Issue'.

Sorry for being busy and not responsive.

Most of the rendering comes from a software written by my friend Martin Bokeloh: http://graphics.stanford.edu/~bokeloh/

Povray is another software I frequently use. It has almost the best rendering quality you can expect, though it is slow. (It is open source too.) http://www.povray.org/

Hope this helps! Also, it is not an issue, I will close it, :)

Thanks, Qianyi

Thank you very much Qianyi, it's very helpful. I wonder if I can ask some questions about your work, SLAC.

The calibration function C(.) is represented by a 8^3 / 16^3 resolution volumetric grids which covers the volume of 3 meters (by default), but there are quite a large portion of voxels lying outside the frustum of a camera, right? How about culling those unused voxels off to further decrease the number of variables being optimized? Or are there some specific considerations to keep them?

BTW, I notice that you havent updated the dataset yet. Are those data coming soon? Actually, I manage to get your code compiled and am working on creating a testing sequence based on the stonewall dataset you released on your webpage. I would like to share my work here when I'm done. I'm looking forward to having more discussion with you. Thanks again!
