Bug Reports / Issues importing mask from PNG transparancy
« on: July 11, 2013, 11:44:38 PM »
I have successfully made a few models by importing masks from PNG files with transparencies, however  I have encountered a problem. I have a project where some of the masks import and some of them do not. Coincidentally, the masks that import correctly are landscape, and the ones that do not are portrait. all the PNG files were created the same way using photoshop. The portrait images do not create a mask when trying to import the PNG as a mask, however the photoscan masking tools do still work. I can send sample files if needed.

Feature Requests / Multiple Masks Per Photo
« on: June 14, 2013, 01:00:59 AM »
When using a turntable setup I have found some objects need to be clamped or turned multiple different ways so you can see the whole object. I have sometimes found it useful to use first do a "rough" mask out clamps and tables during the alignment, and then after alignment I will refine the mask out everything I do not want later in the geometry or the texture.

I think it would be helpful to have an option to hide/unhide masks or to duplicate a mask. Then you could select which mask was to be used for processing in that chunk. I imagine you could treat each mask as an image as place it as a sub-image within each "camera". I think this would fit well within the Workspace hierarchy. Then you could just right click on which mask you wanted visible. This would also help for just experimenting with different ways to mask your object without just resetting the whole mask.

It may be cumbersome switching which mask you want but maybe someone else has some other ideas on how to make this better.

Bug Reports / Minor Bug when changing masking tools

When using the intelligent scissors tool, but not completing the polygon, the selection will remain active if you switch to a different a different tool such as the rectangle selection tool. After doing this, the rectangle tool will still work fine, but there is a ghost image of the intelligent scissor tool while it is still trying to close its polygon. If you switch back to the intelligent scissor tool it will allow you to complete the polygon you started.

I find myself using the orthographic view for over 90% of my workflow, however photoscan is always defaulting to perspective view. I find this annoying because it is much more difficult to create an accurate bounding box while using the perspective view and that is one of the first steps.

This seems like a simple fix by adding setting for default of perspective / orthographic in the photoscan preferences

General / Maximum points per photo

What do I need to consider for optimizing this setting in the preferences? Is this mostly dependent on how many MP my camera is? and if so, what would the ideal value be for a 12mp or a 18mp camera?

General / Export chunk to separate .psv file?
« on: February 09, 2013, 11:09:49 AM »
Is there a way to export a single chunk to separate .psv file? This would be useful for me because I create photos for multiple objects and then process them at the same time using the batch tool. So when I finish I want to reorganize the project files into their respective folders. I could copy the same .csv file into each folder and then open each one up and delete the extra chunks, however this seems time consuming so I am looking for a better way.

Feature Requests / Add "Section View" tool for temporary cutaway view
« on: February 08, 2013, 12:29:57 AM »
Since most of the objects I am creating are not planar, I am finding that when I use the selection tools to delete faces I do not want, I often end up selecting the front faces as well as the back faces of my model. Other software I have used avoid this by using a section view tool that will allow you to make a temporary cutaway. This can be done by moving or rotating a plane to the position you want and everything on one side of the plane is hidden from view. Something like this would allow the current selection tool to work more effectively and would also allow you to more control to look at certain "hard to get to" faces on the model.

Feature Requests / User friendly view rotation & zoom
« on: February 06, 2013, 08:42:12 PM »
I have a suggestion to improve the view rotation and zoom in PhotoScan, since I find it to be a little clumsy compared to other software I have used.

The default view rotation in Photoscan appears to rotate around the center of the model, which is great unless you are zoomed in on a specific area and want to rotate around it. This is where Photoscan gets clumsy.

My favorite style of view rotation is in a mechanical modeling software I use called Solidworks. Solidworks will similarly rotate the view around the center of the object, but it also has an additional way to rotate the view using the cursor depending on if the cursor is hovered over the model or over free space. If the cursor is hovered over free space, then the view will rotate around the center of the object, but if the cursor is hovered over the model, then the software will rotate around the "selected" surface the cursor was hoovered over. This allows you rotate around a specific area while zoomed in. This eliminates the need to be constantly panning around to get to what you wanted to look at and is much more user friendly.

Another feature Solidworks utilizes is when zooming with the mouse wheel. The viewport will zoom towards when the cursor is located on the screen. This can be useful because it also eliminates the need for panning completely if you just move the wheel in and out towards the selected area you want to look at.

I am not suggesting you eliminate the pan feature, it is a good tool, however these additional techniques seem to be a lot faster than the way Photoscan currently works.

I found an older youtube video that describes what I am talking about.

Feature Requests / Multiple shapes for region selection
« on: February 05, 2013, 03:18:52 AM »
The current region selection tool is a rectangle, can you add an option for different shapes such as a cylinder, sphere, or cone? This could eliminate unnecessary calculations for round objects.
