https://community.intel.com/t5/Intel-Integrated-Performance/Simple-realistic-rendering-example/m-p/815533#M4252 Good morning,<DIV>I am trying to create simple rendering program with IPP. I have scene with one triangle and I am casting rays one by one through the scene. When the ray hits the triangle I want to mark the position on the image plane with white color.</DIV><DIV></DIV><DIV>I went through all the examples I could find and I still cant get it working. I cant understand why my program is producing such strange images, but I think that I am not using the camera and the image plane properly.</DIV><DIV></DIV><DIV>Could you please give me some hints or explain how should I position the camera and the image plane properly.</DIV><DIV></DIV><DIV>I have attached my code. Please help me.</DIV><DIV></DIV><DIV>Souce code:<A onclick="ndownload('http://software.intel.com/file/39059')">main.cpp</A></DIV><DIV></DIV><DIV>EDIT: I finally found my mistake. The data was OK but the representation was bad.</DIV><DIV>But I still cant understand how the camera positioning works. Is there anyone who can explain it?</DIV> Sun, 09 Oct 2011 07:56:32 GMT paul_1 2011-10-09T07:56:32Z https://community.intel.com/t5/Intel-Integrated-Performance/Simple-realistic-rendering-example/m-p/815533#M4252 Good morning,<DIV>I am trying to create simple rendering program with IPP.
