The texture rendering quality and how to use multiple texture images

[czw0078]

Thank you for your wonderful job on building this amazing differentiable renderer. I am currently trying to reimplement experiment in your ECCV 2014 paper.

Well, I have two question

(1) How to improve the quality of texture rendering? I mean I tried several demos and also my own mesh data, the texture rendering looks blurring. For example, even in the earth demo, your own example(uses an earth map picture as the texture image) lines do not look sharp after rendering. I know that, if you simply use a png image as a texture image, it becomes blurring due to the enlarge and shrink. So can we use vector format image as a texture? Or in general, how to improve the visual effect in general? I mean your ECCV paper showed amazing indoor rendering scene, how can I have the same level of rendering result? Do you have materials so I can re-implement this experiment?(if you willing to share, that will be great. otherwise some general guides will also helps me a lot)

(2) How is your workflow/utility of editing the data you suggest me to do? I mean the OpenDR provides the render API, which is very nice, but I found so far I spend a lot of time to extract the data from a 3d model file and import data, nevertheless to editing it. For example, if I have multiple texture files, I have to manually put the texture data together as one image, then give it to the TexturedRender. Does the OpenDR provide some file reading utility, so I can edit a 3d object in another editing tool and them save it as some file format, then the OpenDR just read the file format and do the rendering? By the way, what editing tool you suggest to use for most convenience?

Thank you so much for answer my question.
