Graphical core
-
Further development of the LIRA-CAD graphics module based on a programmable rendering pipeline has made our graphics even more expressive and interactive. The speed and quality of visualization have been significantly improved.
Capabilities have been expanded for both the latest hardware and “time-tested” video cards. Alongside existing visual effects such as cast shadows, surface relief, diffuse shading, and others, new features include dynamic “sliding” highlighting of structural elements following the mouse cursor movement, and delayed “lazy” highlighting of structural elements in the area of interest. These reveal hidden geometry and make user interaction with the model more efficient.
Updated graphics engine
The graphics engine in LIRA-CAD 2025 has been updated to support OpenGL 4.6 graphics. It allows for greater compatibility with graphic equipment from various manufacturers and enhances visualization of designed objects.
- The speed for model rendering is increased. Now when you change the view, rotate or perform other actions with the model, the screen refreshes 7-10 times faster compared to previous versions.
- The quality of textures, labels, texts and lines is improved.
- Visual effects of falling shadows, relief surfaces, fog and diffuse shading are implemented.
