Postshot Releases V0.3

It’s a busy Friday! Postshot is getting a major update with the release of V0.3. With today’s rollout, there are a litany of new features aimed at making the user experience stronger. Users will be happy to know that Postshot now supports editing of Splats in viewer, meaning that you can now delete artifacts or other floaters.

Additionally, the limit for Splat count has been increased from 4-10, allowing for even more detail in your captures to be shown! The full changelog is below.

Changes

Training

• Added Preferences/Show Training Error to show PSNR (NeRF) or SSIM (Splat) in progress pane

• Support input image masking based on alpha channel also for Splat model

• Added option to assume black input background (experimental for synthetic datasets)

• Fixed occasional failure of camera tracker that was unrelated to the images

• Fixed failure to import COLMAP poses if ‘sparse’ folder contains unexpected files

Editing

• Added splat selection and deselection tool

• Added ‘Invert Selection’ action

• Added ‘Delete Selected Splats’ action

• Added ‘Use Source Transform’ button to restore original scene scale and orientation

• Crop box did not transform correctly if radiance field had been rotated

Import

• Support HEIF image format

• Fixed hang in some cases when importing variable frame rate video

• Fixed issues with file paths containing Unicode characters beyond Extended ASCII

• Fixed import failure when importing fewer poses than images

• Matching image file names to camera pose imports was too restrictive, leading to failed imports in some cases

• Fixed degenerate camera poses after re-orientation in some cases

• Camera tracking was pronounced failed too conservatively

• Removed upper limit on image resolution

• Prevent repeated error messages when image files are missing

• Image pre-processing progress did not show when importing poses

• Fixed an image selection issue when importing poses

• Ignore .db files (like Thumbs.db) for import instead of aborting import

• Importing images from network drives resulted in errors during tracking or camera pose import

• Fixed crash when importing and resizing RGBA images

• Abort import of camera poses if none match any imported images

Rendering

• Added Max Opacity parameter (aka Olli Huttunen’s Ghost Wall parameter)

• Added option to render Z Depth

• Added Invert Depth and Max Depth parameters

• Rendered image/video files were cropped in some cases

• Fixed missing frames at the end of rendered video files in some cases

• Render to image sequence was broken

Export

• Apply scene transform and crop box to PLY exports

Camera Navigation

• Added Pan/Tilt/Roll Speed parameter in Scene/Viewport Camera

GUI

• Added Window/Reset Layout to revert changes to the UI tabs

• Update ‘Elapsed’ timer independently from progress bar

• Scale-to-fit rendered image if camera resolution is larger than viewport

• Don’t popup message dialogs outside of main window

• Training progress bar did not activate in some cases

• Scene transform was not applied to sparse points in the viewport

• Fixed a crash when selecting ImageSet as viewport camera on large images

• Radiance field transform was not adjusted for when using Image Set as viewport camera

• Max Image Count UI did not update accrd. to selected Image Selection option

• Camera focal length was incorrectly changed when changing resolution

• Sparse points were temporarily drawn in black in some cases during camera tracking

• Some errors during import were not shown as popups (only in log)

• Use higher precision for training steps counter (for step counts > 1M)

• Increased maximum for Splat Scale from 4 to 10

• FOV was not updated when changing camera resolution

• Viewport camera did not update when deleting selected camera

Postshot remains downloadable straight from the Jawset website for Windows. I’ve been seeing a lot more people using Postshot, which has made me really happy. It’s a great platform that simplifies the radiance field creation pipeline.
