NXt produces realistic results by simulating light transport in your model. Unlike many rendering products, there are very few settings to worry about or understand. You provide materials and lighting and press the Render button.
With nXt you don’t need to be a professional renderer to get realistic results quickly. This is simply a graphical tool for editing the mask.Flamingo nXt allows you to easily create stunning, life-like images in Rhino. Changing this color or the setting of the checkbox does not change the masked color. Use the Color Selector provided to select the display color of the masked pixels. Graphically displays the effects of masking as the parameters change. The underlying material could simply be transparent, but sometimes it is useful to make the surface behind the decal transparent while keeping other areas of the surface opaque. Transparent masking allows a more natural shadow and allows the background objects to show. Normally, the material of the object shows through in that area. Makes the masked area of the underlying object transparent so other objects or the background behind the object can be seen through the object. Inverts the mask-pixels that would have been masked are now included, and vice versa. This control is only available when the Color option is selected. The value determines the magnitude of partial masking around the masked color. Must be greater than 0.0 for color masking to occur. The value indicates the size of the area around the color that is also masked.
See the Color Selector topic for details. Use the Color Selector to set the main color. Click on the Color Dropper, then on the bitmap to pick the color. Color DropperĬlick to select the mask color from the bitmap. Selecting the Color option will activate the Color Dropper, Color Selector and Sensitivity controls.
There is also a sensitivity number to make the mask more or less sensitivity to a single specific color as a masked color. If alpha channel does not exist in an image, a color in the image can be specified as a mask. the image pixels will blended with transparency. If the Alpha channel is 100%, the images pixel will be complete transparent. The value of the alpha mask determines the intensity of the pixel color. The alpha channel is an 8-bit (256-level) grayscale representation of the image that masks the color of the underlying pixel. Each pixel in an image is described as channels of data that define the mixture of the red, green, and blue (RGB) colors. Alpha channels create and store masks that let you isolate and protect parts of an image while you apply color changes, filters, or other effects to the rest of the image. The alpha channel is a portion of each pixel’s data that is reserved for transparency information. On the right is the image over a water surface. The gray checkered area represents the image alpha channel. Uses the image’s alpha channel to define the masked area if one exists. Without masking (left) the image covers the surface, with masking (right), the red material shows through. The material assigned to a planar surface in this example has a red base color Masking allows the material to show through the image where the alpha channel or masking color exists. With no masking, the image obscures the underlying material. Masking information can come from three sources in the bitmap: In this example, an image with an alpha-channel background is placed as a decal on a rectangular surface. This allows textures to have complex shaped boundaries and create complex effects such as holes in a surface.
Obscures portions of the image based on either a color value or an alpha channel stored in the image.
