Image Filter


Saturation This node modifies the color saturation of an image and provides the result as a new image.
Invert This node inverts the colors of an image and provides the result as a new image.
Intensity This node modifies the color intensity of an image and provides the result as a new image.
Gamma This node modifies the gamma value of an image and provides the result as a new image.
Brightness/Contrast This node adjusts the brightness and contrast of an image and provides the result as a new image.
Adjust HSV This node modifies the colors of an image in the HSV color space and provides the result as a new image.
Gaussian Blur This node applies a Gaussian blur filter to an image and provides the result as a new image.
Simple Blur This node applies a simple blur filter to an image and provides the result as a new image.

The Image Filter node provides the possibility to adjust and modify still images. These filters implement some basic and frequently used post-processing filters. As the output of such a filter node is again an image it is possible to link multiple filter nodes to create a post-processing chain. The filtering has to be done before the image is converted to a texture via the Image To Texture node.

These nodes are not real-time capable! Changing any input parameters causing the renderer to stall! Use these nodes only during the load/initialization phase of a Scene.



All filter nodes have an ImageSource and ImageResult property. The Active property makes it possible to deactivate a filter node. In that case the source image is just passed through without any manipulations.

Saturation

Using the Saturation node, you can manipulate the color saturation of images. The Property SatLevel defines the color saturation. With a value of 1 no change in the saturation takes place. A value of 0 leads to a fully desaturated image. Values greater than 1 increase the saturation. Use a value less than zero for photo-negative re-saturation.

Invert

The Invert Node creates a photo negative instance of the original image.


Intensity

The Node Intensity modifies the color intensity of an image. The property Intensity defines the increase of color intensity.

Gamma

The Gamma Node gives you the possibility to perform a gamma correction on an image. Via the property Gamma you can change the gamma value of the image.

Brightness/Contrast

Using the Brightness/Contrast Node you can change the brightness and contrast of an image. The property Brightness controls the brightness of the image. Positive values increase the brightness and negative values decrease it. The property Contrast adjusts the contrast of the image. Positive values increase the contrast and negative values decrease it.

Adjust HSV

The Adjust HSV Node enables you to manipulate the HSV (Hue, Saturation, Value) values of an image. Using the Properties Hue, Saturation and Value you can modify the corresponding color channels.

Gaussian Blur

The Gaussian Blur Node is used to blur an image. The property Sigma defines the strength of the blur process. Compared to Simple Blur this node gives better results but the calculation takes longer.

Simple Blur

The Simple Blur Node is used to blur an image. The properties Intensity and Size control the kernel of the blur filter and thus the blurriness of the resulting image.
