With the enhanced real-time renderer in Allplan 2020, you can not only choose any resolution for the image but also define different light temperatures. You can use tone mapping to achieve a warmer, neutral or cold appearance. White balance corrects the color temperature of natural light sources such as sky and sun. And thanks to the two-point perspective, you can eliminate distortions in no time at all.
You can find these new options in the View type palette of the Rt_render rendering method.
Advanced maximum resolution
The maximum resolution for a rendered image is 16,000 x 16,000 pixels. For example, you can thus print HQ posters directly from the rendering result without problem.
Any image resolution
In earlier versions, the resolution of a rendered image of the RTRender view type was dynamically linked with the size of the viewport. In other words, to change the resolution, you had to change the size of the viewport. So, this made it difficult for users to resize images exactly to obtain a certain resolution.
Now you can define the required image resolution directly. To do this, you can enter any resolution in a range between dx = 100 and 16,000 pixels and dy = 5 and 10,000 pixels.
This is particularly important for rendering spherical panoramas, because they require an image resolution at a ratio of 2:1.
Tone mapping and white balance
Think of scenes with great differences in brightness, for example. When you rendered such scenes in earlier versions, bright areas illuminated directly were often overexposed.
To eliminate this effect, you can use two new post-process settings:
Tone mapping:
When you render scenes with great differences in brightness, you can readjust overexposed areas by reducing the dynamic range. This is particularly useful for scenes that contain both bright areas illuminated directly and shaded areas.

White balance:
You can readjust the color temperature of the rendered image to the lighting of the rendered scene. You can use values between 1,000 and 10,000 Kelvin.

Two-point perspective
You can use the new two-point perspective to eliminate distortions. Vertical edges always appear vertical.

New method for noise reduction
To enhance rendering results, Allplan comes with a new noise filter for noise reduction.
The former noise filter tended to blur the rendered image, which was particularly true when you rendered surfaces with textures:
The new noise filter produces rendering results that do not blur even when you render surfaces with textures.

Faster resizing of viewports
When you change the size of a viewport in which Allplan is rendering an image, Allplan is now faster to recalculate the image, adjusting it automatically to the new size.
When you changed the size of a viewport of the RTRender view type, earlier versions rendered the scene from scratch. This was quite time-consuming, especially when rendering large or complex scenes.
When you resize the viewport now, Allplan adapts the image it is rendering, not stopping the current calculation.
