Summary | 0008315: select points on and select cells on select points outside the frustrum | ||||||||
Description | load the associated state file The camera is far away from the dataset try to select the cells on the top half of the wavelet --> some cells are selected on the other half of the wavelet. (see screen shots) | ||||||||

The select cells on function works by doing a "pick" render and reading cell ids out of the frame buffer. Thus, what is selected is whatever the renderer says is in the front. It looks like your graphics card is having some z-buffer fighting that is allowing cells in the back poke through to the front. I cannot replicate this on my system. Why type of graphics card do you have? |

I understand that the "select points on" and "select cells on" use that graphic card and read back values written on the buffer. This is why some cells are not seleteced and it is ok. The problem here is that the selection finds cells that are *not* in the frustrum. In the zoomed image, I only zoomed in, I did not modify the camera orientation and selected only the top of the wavelet source. My graphics card is a Quadro FX 1600M (laptop) |

That can happen if anti-aliasing/multisampling is turned on, (in which case colors rendered get slightly distorted resulting in incorrect interpretation. |
