X-Ray View

With NUBIGON, you can display point clouds in x-ray mode. This mode can be activated for splat surface materials.

X-ray view is compatible with all main display modes (point color, object color, intensity, and elevation) and color scales.

When using x-ray view, the entire depth of the dataset needs to be rendered to simulate transparency. Depending on the data size, this may require quality adjustments for the following use-cases. 

X-Ray View for Viewport Rendering & Screenshots

To boost viewport render quality, you can edit the performance settings by increasing GPU cache and decreasing Minimum coverage under Edit > Preferences. Beware, this may slow down the viewport rendering.

X-Ray View for Orthophotos

To effectively use x-ray view in orthophotos, you may consider increasing VRAM per tile. Keep in mind that this can prolong orthophoto generation.

If a high-resolution orthophoto appears too dark or sparse, increase the X-ray point size.

Generating an orthophoto renders more points than visible in the viewport. This can lead to over-exposure. You can counteract this by increasing the White parameter in the Object Inspector before orthophoto generation.

X-Ray View for Videos 

To render videos from point clouds in x-ray mode, maximize the VRAM usage in the Render Video dialogue. This will reduce the point-loading effect and thus produce the best results.

Generating a video with increased VRAM usage renders more points than visible in the viewport. This can lead to over-exposure. You can counteract this by increasing the White parameter before video rendering.

Tips for X-Ray View

If you display a point cloud in x-ray, do not open other meshes or point clouds as this causes visibility issues.

Avoid combining clip animations and x-ray in rendered videos since this may cause frequent exposure changes.

When generating videos, a maximum of 8 GB of the dataset is rendered in each frame. Be mindful that this may cause visible boundaries between different levels of detail (see the image below) due to the characteristics of the x-ray view.
