Real-time visualisation

The term real-time visualisation means display of a 3D-model close to reality while changing the camera. As opposed to this, the rendering generates a static image or video.
Because the camera remains changeable, a fast screen refresh rate is required. This is accomplished using the shader technology. Shaders generate material visualisation on 3D-surfaces in real-time. Surfaces with complex structures and depth effects are depicted on flat surfaces, which need less memory. This process takes place on the graphics card and therefore enables huge performance gains.

Workshop

For the efficient usage of real-time visualisation, a few steps are necessary.

  • Activate the Shader-Technology in the solid mode.
  • Use visualisation materials with shader material properties (e.g. grass, water, bump maps).
  • Activate the shader effects under Settings > Input devices.
  • Define a 360° background image for the current view in the view parameters. 360° background images can be stored in the material manager.
  • Switch to the walking mode.
  • Use a gamepad for navigation through the model.
  • An optimal experience of a virtual 3D model is achieved in a Virtual Reality environment. If available, activate VR glasses.

Shader on/off

Icon1 Image properties

This check box controls the use of shader technology in the solid model. Depending on whether the check box is selected, the shaders are activated or deactivated. Object reflections for mirroring surfaces are pre-calculated only once. Depending on the model size, this process can take several minutes. According to the configuration, reflections are automatically calculated when activating the shader technology (SETTINGS > OPTIONS > DEPICTION > 2D/3D, the walking mode (VIEW > CAMERA > CONFIGURE INPUT DEVICES > WALKING MODE or the calculation is manually launched.

Re-create object reflections

Icon1 Camera toolbar
Menu view > Camera > Re-create object reflections

This function is used to re-create the object reflections for the shader mode. An automatic calculation can be activated in the OPTIONS under DEPICTION > 2D/3D.

Delete object reflections

Icon1 Camera toolbar
Menu view > Camera > Delete object reflections

This function is used to delete the object reflections for the shader mode. An automatic calculation can be activated in the OPTIONS under DEPICTION > 2D/3D.

Update object reflections

Icon1 Camera toolbar

This function is used to update the object reflections for the shader mode. An automatic calculation can be activated in the OPTIONS under DEPICTION > 2D/3D.
