The image should have a resolution specified by the user. I was thinking about using bounded 2D cut planes through my geometry and and generate a certain pixel value at the position of the pixel, where a triangle from my 3d surface cuts this plane. After generating a lot of these 2d images along a certain axis (the distance of the planes is the diameter in z-direction of the geomtry devided by the resolution of the image in z-direction), I want to combine these images to a 3d image volume. Is there any easier way to handle this?</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Yours sincerly,</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Andreas Lintermann</DIV><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">-----------------------</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Aerodynamisches Institut und Lehrstuhl für Strömungslehre der RWTH Aachen</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Institute of Aerodynamics and the Chair of Fluid Mechanics of RWTH Aachen University</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Andreas Lintermann</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Webdesign and Network Administration</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Tel:<SPAN class="Apple-converted-space"> </SPAN><SPAN class="Apple-tab-span" style="white-space:pre"><SPAN class="Apple-style-span" style="white-space: pre; "> </SPAN></SPAN><SPAN class="Apple-tab-span" style="white-space:pre"><SPAN class="Apple-style-span" style="white-space: pre; "> </SPAN></SPAN>(+49)-241-80-95415</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Fax: <SPAN class="Apple-tab-span" style="white-space:pre"><SPAN class="Apple-style-span" style="white-space: pre; "> </SPAN></SPAN>(+49)-241-80-92257</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="mailto:A.Lintermann@aia.rwth-aachen.de"><SPAN class="Apple-style-span" style="color: rgb(0, 0, 238); -khtml-text-decorations-in-effect: underline; ">A.Lintermann@aia.rwth-aachen.de</SPAN></A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><BR class="khtml-block-placeholder"></DIV><BR class="Apple-interchange-newline"></SPAN> </DIV><BR></BODY></HTML>
