Transparency #5

Open pgerhardstein opened 12 years ago

pgerhardstein commented 12 years ago

I need to understand exactly what the program does w. the mask in order to be clear on what I need to do w. the transparency. Eliminating the transparency eliminates all of the specularity and other photo features (makes the pieces appear 'flat'), so that is not a real option. I think that there is a mask issue in which not all of the background pixels are the same color; this may be part of the smoothing issue. If possible, it may be helpful to have a conversation at a point when I can open the image files and look at the pieces (I'm not sure this is necessary, but it seems like it might be useful).

I'll look into it in more detail but I suspect that the border of the object need to be transparent.

I think so too. By the way, don't do anything re the "smoothness" issue yet - I've just finished a survey of manufacturers, and we are using the wrong technology. Capacitive touch screens are MUCH smoother - I've tried the Sony Vaio version, and a feather-touch will move an object. We will switch hardware and retest.

Okay. The program does not add any additional filtering so the issue is the transparency on the images. Adding transparency to the object boundary (in Gimp) doesn't seem to help much because it de-emphasizes the specularity. I'll try adding a light source but not sure how effective that will be since the pieces aren't 3D models.

Don't think it will help; I'm trying to simply reduce the transparency. I've ordered a new touch screen, which the sales rep says will respond very much like an iPad. It also apparently has a driver feature to allow us to tune the pressure-related sensitivity. It is capacitive, so finger-touches are its design target.
