Scanline render crashes

<< < (2/2)

Steve:
Yes, the scanline renderer splits all polygons into triangles and  builds a giant table of them. Then as the render advances and reaches a triangle, all of its edges' positions, slopes, texture coordinates, normals, and their derivatives, are added to the edge-table for rendering, which is advanced line-by-line during the render. There is a very large number of triangles in all those flowers in your scene, and the tables simply get too big.

The ray tracer uses less memory because it doesn't need the edge table with all of it's derivatives, etc. It just needs the triangles.

AlecJames:
This came about because I made one flower with a lot of detail and copied it. I don't need the detail because the flowers are so far from the camera you can't see it so I set about making a minimum face flower and copied that instead. I added the new flower (and many more) to my scene and the memory used during render is 500MB ish, well within now :)
