Orthogonal lines glitch in volume rendering #75

Open tnikodym opened 5 years ago

Version: GVDB 1.1 Commit: 1f269ced2

Current behavior: Rendering volumetric data with the built-in render kernel (SHADE_VOLUME) produces a visual artifact (1px wide white orthogonal line) that appears to be along the brick boundaries.

Research: The visual output depends on the configuration of the topology (in particular, on the last argument of GVDB::Configure method).

The glitch is only apparent when F_LINEAR interpolation is used and the resolution is sufficiently large (tested on 3840x2160).

Below is a detail of the visual glitch: detail-c33334
