Darkness controls the opacity of the shadows.The Thickness, Line overstretch and Line distortion controls have the same effects as they do in the Sketch Line Settings panel.If the Show Vectorial Sun Shadows checkbox on the Basic Settings panel is not active, no shadow lines will be shown and the choices you make here will have no effect whatsoever. The controls on this panel set the properties of the shadow shading lines of the rendered image. These settings only take effect if you check the Apply box. Without clarifying the remote area the hatch lines would be so dense that they would form a continuous dark area. This is useful and sometimes even necessary when a hatched surface is viewed from a reduced angle. When the Clarify remote area control is set high, the hatch lines in the background will be paler and thinner. The Thickness, Line overstretch and Line distortion controls have the same effects as on the Sketch Line Settings panel. If the Show 3D Vectorial Hatching checkbox on the Basic Settings panel is not active, no hatch lines will be drawn and the choices you make here will have no effect whatsoever. The controls on this panel are to set the properties of the hatch lines of the rendered image. When the control is set low (below zero), the lines will stop short of reaching one another. Line Overstretch is set high, the lines will be longer than their counterparts in the ARCHICAD 3D window, as if you had been drawing lines that do not connect properly and will cross each other.Generally, to replicate a pencil stretch you will use a lesser distortion than for brush, but you can experiment. Line distortion: Try various values with the chosen line style to achieve the desired effect.
For best results, use higher values for Sketch Lines than for Hatch Lines and Shadow Lines. However, you can experiment with different line settings and try getting interesting results which can be varied for a given line style. Large values are appropriate for displaying the textures of brush or wax.
Try loading any of these background images from Document > Creative Imaging > Photorendering Settings > Background. This setting has no effect if no background image has been scanned with the alpha channel.įor samples, go to the ARCHICAD folder and open ARCHICAD Library 20/ Background Images 20/Alpha Paper Textures 20. The sketch engine can detect these bumps and fade or erase the sketch lines at this area depending on the settings of the Paper Roughness slider.
Normally, bumps are generated randomly by the rendering engine however, for best results, it is advisable to use a background image with predefined alpha channel for the bumps
Although this effect is not normally done with manual sketching, a light air perspective to a rough wax sketch can be an attractive enhancement, and can be made to look especially natural with brush scans. Air perspective: Similarly to the Fog effect, fades lines further to the viewpoint.brush, chalk), it is recommended to keep this value low (2 or less), as high values can slow down rendering. Antialiasing: Smoothens the lines by picking longer lines from the scans than necessary.The shade lines properties can be set on the Shadow Line Settings panel. With Show Vectorial Sun Shadows active, the rendered image will include shaded areas representing sun shadow.The properties of the hatch lines can be controlled by the settings of the Hatch Line Settings panel below. If you check the Show 3D Vectorial Hatching box, the hatch lines (for example brick or tile contours) will be drawn in the rendered image.As in Line Style: For the most natural effect, the color of the lines can be determined by the scans’ original colors (graphite pencils, black art pen ink, sepia and peine gris aquarelles, and carmine.).Color images can be generated this way however, it requires the careful adjustment of pen colors. Current element settings: In this case, line color depends on the pen colors of individual model elements.The presets suggest traditional black, blue or tan colors. Custom: Any preferred color can be chosen for monochrome images.
