Rendering method palette (for RT render method)

Rendering method palette
View Type tool (View menu)
View Type list box (viewport toolbar)

You can use the RT render rendering method to render the current view. If you change the scene or model, the program starts rendering the image again. The longer you do not change anything, the better the resulting image.

The predefined RTRender view type is based on this rendering method.

Note: The settings you make here apply only to the image on screen. If you want to calculate a bitmap, the program uses the settings in the Render tool.

Parameters

Name

You can change the name of the view type.

Rendering method

RT render (cannot be changed for the predefined RTRender view type)

Settings

CPU power

By entering a percentage, you can define how much CPU power you want to use for RT rendering at most.

The higher the percentage, the faster the CPU or the faster it can render the image. However, this may slow down other applications.

In order to prevent this, reduce the CPU power reserved for RT rendering.

Rendering progress

When you select this option, you can see information on the rendering progress directly in the viewport. For example, you can see the time the program has used so far to calculate the current view and the time it will require to calculate the next frame.

Stop criterion

If you want to set a time limit for RT rendering, you can define a stop criterion:

• Off:
  There is no stop criterion. RT rendering is infinite. In other words, Allplan calculates the image until you change the view.
• Frames:
  Specify the number of frames. You can enter a value between 5 and 10,000. Allplan stops as soon as it has reached this number.
• Time:
  Specify the total time of the calculation. You can enter a value between 5 sec and 23 h 59 min 59 sec. Allplan stops as soon as the time specified has elapsed.
• Quality:
  Define the quality. You can choose between four levels: low, medium, high and very high.

  Automatic exposure

  You can choose to correct the exposure of the image:

• Off:
  Automatic exposure is off, but you can control the brightness using the Exposure setting on the viewport toolbar.
• Mean and Median:
  With normal lighting, the two settings produce similar results.
  But the situation is different with extreme lighting: Median is well suited for scenes with strong light in the background, such as views of rooms by daylight with a view to the window. Mean, on the other hand, is better suited for overexposed scenes where you want to neutralize overexposure, such as scenes at night with street lights.
  Summing it up, Median brings out dark areas, whereas Mean balances out areas that are too bright.

  Examples of rendered images with different settings for automatic exposure:

  

  Comparison of rendered images with different settings for Automatic exposure: you can see the effects of Median (left) and Mean (right) on an interior scene (top) and an exterior scene (bottom).

  Noise reduction

  Filter

  You can choose to reduce noise.

  Intensity

  You can define the intensity of noise reduction.

  Smoothing

  You choose to smooth edges.

  Examples of rendered images with different settings for nose reduction:
