User manual DIGITAL ANARCHY PSUNAMI

[. . . ] PSUNAMI WHAT IS PSUNAMI? Digital Anarchy Psunami is a plug-in for Adobe After Effects 4. 0 or later, which simulates photorealistic oceans and skies. Psunami creates the illusion of real water and air by modeling the true physics of large-body water and atmospheric systems. This is accomplished by creating a genuine 3D environment within After Effects, with polygonal modeling, geometric displacement mapping, a 3D animatable camera, animatable light sources, and raytracing with reflections and texture mapping. Within this environment, you can fully animate the camera in three dimensions, precisely control waves and swells in the ocean surface, simulate haze and rainbows in the atmosphere, and animate two "suns" at once, for fine lighting control. [. . . ] HLS, or the Hue/Lightness/Saturation color system, defines color as a position on a color wheel. Hue is the angle of the position of the color point on the wheel relative to 0 degrees. HLS defines saturation as the linear distance of a point on the color wheel from the center of the wheel. As you can see, Hue and Saturation generally do not produce satisfactory displacement mapping, and Red, Green, and Blue rarely produce positive displacement. In most cases, you'll get the best results from the Alpha, Luminance, or Lightness DISPLACE ON options. You can view the Luminance, Lightness, Hue, and Saturation color components in Grayscale (Icons) RENDER MODE, by the way. 38 PSUNAMI IMAGE MAPS Displace Intensity DISPLACE INTENSITY sets the amount of displacement your map will produce. A value of 0 causes no displacement; higher displacement values will produce a higher average displacement. The image on the left shows a Displace + Texture On image map, displacing on the alpha channel with a DISPLACE INTENSITY value of 2. The image on the right shows a DISPLACE INTENSITY value of 10. Negative displacement values invert the normal displacement order, so that light pixels push the mesh down and dark pixels push the mesh up. The image below shows the same displacement map with a value of ­5. You can animate this value to have a logo rise out the sea, for example. 39 IMAGE MAPS PSUNAMI Center X (M), Center Y (M) CENTER X and CENTER Y let you set the position of your image map, in meters, on the ocean surface, relative to the center of the ocean grayscale map seen in the Grayscale RENDER MODES. When you're looking at the ocean surface in Grayscale (Icons) RENDER MODE, the image map's x position is along the left/right axis, and the y position is along the up/down axis. The image below left shows an image map with a CENTER X value of 50 meters and a CENTER Y value of 0. CENTER X and Y values are relative to the center of the grayscale image. Positive X values will position your image map to the right or east of the center of the grayscale image; negative X values will position your image map to the left or west of the center of the grayscale image. Positive Y values will position your image map above or to the north of the center of the grayscale layer; negative Y values will position your image map below or to the south of the center of the grayscale layer. To get an idea of how these CENTER values correspond to position in Psunami's world, you should understand that one pixel equals one meter in the Grayscale RENDER MODES, so a 320 by 240 composition has a visible grayscale area of 320 by 240 meters. So, setting the CENTER X value to 160 will position the center of your image map right on the edge of the grayscale frame (above right). 40 PSUNAMI IMAGE MAPS Angle ANGLE lets you set the rotation, in degrees, of your image map relative to the grayscale plane. Rotation occurs around the center of the image map. An angle of 0° will align the image map with the left/right orientation of the ocean surface as seen in the Grayscale RENDER MODES (below left). With the default CAMERA settings, an ANGLE of 0° aligns the image along the camera's view axis (below right). Positive angle values rotate the image map clockwise; negative values rotate the image counterclockwise. Scale X, Scale Y The SCALE X and SCALE Y properties scale your image map relative to the grayscale ocean plane. SCALE X and Y values of 1 will leave your image map at its original size relative to the grayscale map ­ that is, an image map of 320 by 240 pixels in a 320 by 240 comp will be at the same size as the comp with SCALE X and Y both set to 1 (lower left).
