Lines: 47 I am a new user of SunPhigs 1.3. While trying to create a new Phigs program I encountered the following problem : When I create elements inside the Phigs structure, using my modeling coordinates space, if the modeling coordinates size is larger than ~100, then the element is not displayed on the window. When I use small coordinates as the modeling coordinates , then the display is o.k. Notice that in all the Phigs examples and tutorials, small coordinate values are used. (between -2 and ~15) It seems as if something is wrong with the translation from the modeling coordinates (MC) to the world coordinates (WC). Example : The coordinates in file pickit.c ( in phigs1.3/examples directory) are : static Ppoint3 square[] = { 0.0,0.0,0.0, 0.2,0.0,0.0, 0.2,0.2,0.0, 0.0,0.2,0.0, 0.0,0.0,0.0 }; I changed them to be : static Ppoint3 square[] = { 0.0,0.0,0.0, 200.0,0.0,0.0, 200.0,200.0,0.0, 0.0,200.0,0.0, 0.0,0.0,0.0 }; and with those new coordinates , the pickit program does not work - nothing is displayed on the window !! -- TIA, -- Amir J.
