Marko Koljancic

Marko Koljancic is an independent software publisher distributing open-source development tools through a GitHub repository, with a catalog currently consisting of one product, Solarxy, a 3D model viewer, visual debugger, and validator. Solarxy addresses the needs of developers, technical artists, and engineers who work with three-dimensional assets and require a dedicated environment for inspecting geometry, materials, scene structure, and related data before those assets are integrated into games, simulations, visualizations, or other rendering pipelines. As a viewer, the software allows users to load and examine 3D models interactively, orbiting, zooming, and navigating scenes to assess them from any angle. Its visual debugging functionality extends beyond passive inspection, helping users diagnose common problems in 3D content such as broken normals, missing textures, incorrect transforms, malformed meshes, or shading artifacts, by exposing underlying data in an accessible, visual form. The validation capabilities complement this by checking models against expected conventions or constraints, surfacing errors and inconsistencies early in a production workflow rather than after deployment. Tools in this category are typically used in game development, computer graphics research, CAD-related workflows, and any pipeline where 3D assets pass between authoring applications and runtime engines, making inspection and verification a recurring necessity. Because the product is published on GitHub, it aligns with the open-source distribution model, where source code is publicly available, contributions and issue reports from the community are welcomed, and users can adapt the software to their own requirements. As a single-developer publisher, Marko Koljancic represents the independent segment of the software ecosystem, where focused, specialized utilities are built to solve concrete technical problems and shared openly with peers facing similar challenges in interactive 3D development.
