251 <div class="outline-text-2" id="text-2">
253 Parses scene definition language and creates 3D world based on
254 it. Result will be in a <a href="https://en.wikipedia.org/wiki/Wavefront_.obj_file">wavefront obj file</a>, witch can be then
255 visualized using external renderer.
259 Basic concept of defining scene is:
262 <li>Simple and primitive objects are created on point and polygon level.
264 <li>More complex ones can be created my combinig already existing ones,
265 while applying various transformations on them.
270 Objects with all its subobjects can be rotated, mirrored or resized
271 omong any axis. Generator has built in cache for data input and output
272 to minimize file access.
