A surface can reflect DIFFUSE, AMBIENT and SPECULAR light.\n\ 137 A surface can also emit light. The EMISSIVE parameter allows to define it.\n\ 138 The surface SHININESS can also be modified.\n\ 142 The selected shape's location and geometry can be modified in the Shapes-Geom\n\ 143 tabs by entering desired values in respective number entry controls.\n\ 147 In the Scene-Clipping tabs select a 'Clip Type': None, Plane, Box\n\ 149 For 'Plane' and 'Box' the lower pane shows the relevant parameters:\n\ 151 \tPlane: Equation coefficients of form aX + bY + cZ + d = 0\n\ 152 \tBox: Center X/Y/Z and Length X/Y/Z\n\n" 153 "For Box checking the 'Show / Edit' checkbox shows the clip box (in light blue)\n\ 154 in viewer. It also attaches the current manipulator to the box - enabling\n\ 155 direct editing in viewer.\n\ 159 A widget attached to the selected object - allowing direct manipulation\n\ 160 of the object with respect to its local axes.\n\ 162 There are three modes, toggled with keys while manipulator is active, that is,\n\ 163 mouse pointer is above it (switches color to yellow):\n\ 164 \tMode\t\tWidget Component Style\t\tKey\n\ 165 \t----\t\t----------------------\t\t---\n\ 166 \tTranslation\tLocal axes with arrows\t\tv\n\ 167 \tScale\t\tLocal axes with boxes\t\tx\n\ 168 \tRotate\t\tLocal axes rings\t\tc\n\ 170 Each widget has three axis components - red (X), green (Y) and blue (Z).\n\ 171 The component turns yellow, indicating an active state, when the mouse is moved\n\ 172 over it. Left click and drag on the active component to adjust the objects\n\ 173 translation, scale or rotation.\n\ 174 Some objects do not support all manipulations (e.g. clipping planes cannot be \n\ 175 scaled).
